Growing Syneilesis aconitifolia from seeds

,

Growing Syneilesis from seeds is a straightforward process if the fruits are OK.
The problem of empty fruits it is most likely due to repeated clonal propagation. Syneilesis it is mostly propagated by division which is a much faster method of propagation; however, we end up with large populations having the same genotype.
Syneilesis has bisexual tubular florets (featured image), fertile (according with Flora of China) but like most Compositae it needs cross pollination in order to set seeds. So, in order to obtain a good seed set it is necessary to have in the garden a few plants that were grown from seeds.

For now we will have to contend with the few seeds packets I manage to select from the fruits kindly provided by my friends.
It is really not worth the time selecting those few packets, but I like to do it when I can because not all people have access to buy plants. Their only chance of having this species (and others) in their garden is to grow it from seeds.

Syneilesis is a warm germinator (room temperature) and it can be started indoors under lights or outdoors as soon as the frost danger is gone; the ‘seeds’ germinate in about 10-15 days.

Syneilesis aconitifolia seedlings; they have only one cotyledon and may remain at this stage during their first season.

 

They seem like not growing much in this phase but in fact they grow up good size roots – for this reason it is best not to use very small/short pots for sowing.

After transplanting the seedlings usually go dormant for a while and sometimes put up a true leaf in late summer/fall. Some remain dormant and will grow the true leaves only in the next season.
It is possible that some seedlings will form true leaves right away just like Podophyllums do. This behaviour can be seen in other rhizome forming species as well.
The temperatures and water regime may also have a role in the growth pattern.

I will end with a few pictures from one of the donors’ wonderful garden. The pictures were also kindly donated, so please respect the copyright.

Syneilesis is by definition a foliage plant and you can observe how well it looks in this rich, textural composition with other shade/part shade species.

Compositae (Asteraceae): seeds, achenes and cypselae

, ,

Call them as you wish

Initially I wrote a short post for Growing Syneilesis from seeds for the germination page, and then I thought, wait a minute, it is not the only Compositae with fruits/seeds related problems.
So, I wrote a longer post on the subject and then thought, who’s going to read all this? Finally, I wrote another shorter post, and there will be more flower pictures later.

I think everyone knows that in Compositae (Asteraceae) what seems to be a single flower is actually a cluster – a composite of smaller flowers (florets), usually called a head which contains disk and/or ray flowers; both types can be bisexual or unisexual.
And, many species require cross-pollination in order to set seeds; the pollen has a special presentation mechanism which prevents self-pollination (I will talk more about this for Syneilesis).

Probably many are also aware that what we call ‘seeds’ in Asteraceae are actually fruits. In simple botanical terms they are single-seeded nuts. Scientifically, they have been called achenes by some and cypselae by others (see note).

So, we don’t see, collect and sow the actual seeds, but the whole fruits.
It is often a deceptive situation because copious amount of fruits are formed but most of them are seedless (cypsela is a very good name to illustrate that) – like it often happens in the case of Syneilesis aconitifolia. Another example, from my garden this time, is Achillea ageratifolia ssp. serbica.

Syneilesis aconitifolia – lots of empty fruits

Achillea ageratifolia ssp. serbica, flowering very well last summer, alas just lots of empty cypsalae were formed

Conclusion:

If we call them fruits or seeds is not that important; I myself call them ‘seeds’. The important thing is to understand the distinction and be able to assess the situation when it comes to sowing, namely if you are really sowing ‘seeds’ or just ‘fluff’ (e.g., empty fruits).

This is why it is always a good idea to carefully check the fruits for many species of this family; take a note on Aster spp. and Solidago, Anaphalis, but not only.
Often is easy to select the good ones (which are plump) when observed with the naked eye; sometimes with the use of a magnifier – and a lot of time…The smaller they are, the harder is to distinguish the good ones.
For large quantities of fruits the cut method can be used by selecting samples.

Anthemis carpatica ssp. pyrethriformis – selected good and empty cypselae using a magnifiyng glass

Sowing seedless fruits, no matter what we call them, and no matter the plant family, will never result in germination.
Read about Linnaea borealis and Acer triflorum.

Note: “Fruits of composites have been called “achenes” because they resemble true achenes. Achenes are dry, hard, single-seeded fruits derived from unicarpellate, superior ovaries. Ovaries of composites are bicarpellate and inferior. Fruits derived from ovaries of composites are called cypselae “ – Flora of North America

cypsela – from the Greek kypselé, a box, hollow vessel


 

 

Seedless Friday – Compositae

Well, not quite seedless – here’s one image. I didn’t have time to finish what I wanted to do for the Compositae family and, taking into consideration the weather here, maybe it is for the best. We can really use some colours at this time!

I only have a small collection of genera/species from the  Boraginaceae family. I must work better at this family, that’s for sure.
Here they are for now: Onosma, Omphalodes, Pulmonaria and something a bit more rare, Craniospermum.
And because species placed formerly in Hydrophyllaceae are now included in Boraginaceae, there is also Hydrophyllum.

Growing Podophyllum from seeds, including Dysosma and Sinopodophyllum

,

While in the Berberidaceae realm, here’s a post where I outlined as best as possible, the process of growing Podophyllums from seeds from A to Z.

The Chinese Podophyllums (syn. Dysosma), share similar seeds and germination requirements as our native Podophyllum peltatum (mayapple). In all cases, the seeds are enclosed inside fleshy fruits. After the fruits are collected, it is important to extract and clean the seeds right away. This can be a bit unpleasant because the inside containing the seeds is gelatinous (use a sieve and lightly rub the seeds out and rinse, rinse and rinse again).

The sowing must be done right away (Sept./October) or the seeds must be placed in moist vermiculite in Ziploc bags until sowing. The seeds are easy to keep in moist vermiculite as long as were well cleaned; you only have to check the moisture level once in a while (one exception noted for Dysosma aurantiocaule, when the seeds got soft fast, but I had a small lot of seeds and cannot really generalize).

I must emphasize that these seeds are hydrophilic, and using dry seeds to sow, in my opinion, is a complete waste of time.

Dysosma seeds in moist storage

The required cycles for germination are: Light WARM (late fall temperatures)/COLD.

  1. Sowing outside: the time would be early to late fall. Sow as usual in pots/large containers, water and keep them over the winter in a cold frame. Easy done, no worries!

Podophyllum peltatum, Mayapple, seedlings germinated outdoors showing the cotyledon leaves; they will remain at this stage in the first year and do not need pricking out. Later in the season, they become dormant (do not throw away the pots!)

  1. Sowing indoors: usually done in the winter/early spring with seeds that have been kept moist and allowed a light warm/cold period. The cold period can be provided in a cold garage/fridge. It is not advisable to use this method unless enough light can be provided for the growing seedlings (light stand, conservatory).

If someone wants to speed up the process, the Ziploc bags with seeds can be taken out of the fridge around late January/February and kept at room temperature; gradually the seeds will start to germinate and can be potted up one by one and placed under the lights.

Dysosma hybrids (pleiantha x versipellis, syn. Podophyllum pleianthum x versipelle) seedlings

Or, leave the Ziploc in the fridge until all seeds start to germinate towards spring (approx. March/April) – as well, pot them up and provide adequate conditions until they can go outside.

Dysosma hybrid, seeds germinated in the fridge, April 21

In most cases, only cotyledon leaves will be formed, in other cases the true leaves will appear as well. Usually, Podophyllum peltatum will form only cotyledon leaves in the first season, grow for a while and then go dormant; the Chinese ones are variable, most will form a true leaf. When growing from seeds there is always great variability.
Keep the seedlings in a part shaded place, water and feed lightly. At some point in the summer they may go dormant, especially if very hot weather.

All the seedlings which didn’t form a true leaf in the first year, will do it in the second year. Be patient, like with all other species that form a rhizome. In general, 3-4 years are necessary to obtain a good young plant; they will grow really fast after the root system has bulked up.

Podophyllum hexandrum (syn. Synopodophyllum hexandrum)

The difference in this case is that the seeds are not hydrophilic, so they can be kept dry in the fridge for quite a few years. Of course, when sown fresh (fall), they will germinate in the spring.

For dry seeds, a GA3 treatment followed by sowing at room temperature usually will result in rapid germination, and sometimes most seedlings will present the true leaf. 

Podophyllum hexandrum seedling with true leaf

Important for all species: in the first 1-2 years they put lots of energy into forming their radicular system; this translates in the fact that the seedlings need enough space to develop. So, either sow fewer seeds per pot or transplant them in the early stage in individual pots.
I think my pictures show very well what I mean; learn from my mistakes ;) If you sowed to dense and didn’t prick them early, don’t panic; when still dormant (very early spring), shake the soil, untangle the roots gently and repot in a fresh mix in large size pots.

Podophyllum hexandrum crowded seedlings after one season growth  in the same pot

Podophyllum hexandrum one-year seedlings prepared for repotting, notice the variation in size

Again, there is always variation when growing from seeds; we cannot expect all the seeds, even from the same batch, to grow the same: the collection site, mother-plant, ambient factors, all have an influence in germination & growth of the seedlings. This picture with one year old Dysosma plants shows it very well:

Dysosma hybrid one year old plants, prepared to be repotted

I hope this will be helpful for all wanting to grow any Podophyllum/Dysosma species from seeds – Happy Podos growing!

Friday’s seeds – Berberidaceae

,

This Friday I indulge in one of my favourite plant families; say it out loud – Berberidaceae!

It is a large family and here I emphasize of course, the ornamental side of it. Many known and beloved garden perennials (usually for the woodland gardens) belong to this family: Epimediums, Vancouveria, Achlys, Podophyllums, Jeffersonia, Ranzania, Diphylleia and so on. From the woody species, Berberis and Mahonia are widely cultivated.

What else they have in common, seeds speaking and referring to the perennials, is the fact that in most cases, these are hydrophilic (i.e. do not tolerate desiccation) and so for optimum results they need to be sown fresh or kept in moist storage.
The pattern required for germination in most cases is WARM/COLD, sometimes with multiple cycles (see Caulophyllum).
Hover over pictures for names

Two genera, Caulophyllum and Gymnospermium, present another rarely seen feature in Angiosperms, namely that the ovary walls burst open and the seeds develop and ripen in a ‘naked’ state (they look like fruits, but nonetheless are just seeds). Fascinating.

Gymnospermium altaicum (Pall.)Spach

Caulophyllum thalictroides (L.) Michx.

For more please see the newly published Berberidaceae page, the 10th in line!

I know seeds are boring (but how else can we obtain plants?), so here are few plant pictures, mostly to show species I don’t have seeds yet: Vancouveria hexandra, Achlys triphylla,   a nice, fat Dysosma and a hybrid Epimedium raised from ‘Amber Queen’ seeds (hybrid). For others like Caulophyllum, Jeffersonia, Podophyllum…I already showed pictures many times and they are also featured in the Seeds shop.

Epimedium ex. ‘Amber Queen’, a 3-years old plant flowering in my garden (for Epimedium only hybrids will be obtained when growing from seeds)

Only one more picture, more for the purpose to emphasize the name that should be used for Jeffersonia dubia – guilty of charge myself; I’ll try to go the right way from now on.

Plagiorhegma dubium (syn. Jeffersonia dubia)

Additional pictures will be posted later on FB in order to save space here on the website.

 

 

Fridays Seeds in lieu of flowers – Pulsatilla

,

I don’t remember if I’ve already done a Friday’s seeds about Pulsatilla; in any case this is more to draw attention to the Pulsatilla species from the shop.

There are not many, but all are fresh of this year and this is the best time to sow!
See them here in the Pulsatilla category.

I don’t have many pictures of these gorgeous species, reason why I have to show the seeds. I know they are not as attractive as the flowers but what can I do, and in any case, they can be used for ID purpose.

Pulsatilla albana ssp. armena – the Pulsatilla ‘seeds’ are actually fruits – achenes with “fluffy tails”.

Pulsatilla vernalis


 A good idea is to admire pictures while also reading advice on their germination at the same time – all on the Scottish Rock Garden forum! This is the link to Pulsatilla 2013 thread, but there are more topics on Pulsatilla: http://www.srgc.net/forum/index.php?topic=9988.0

Note: I’ve already sown my batch (I have to practice on this genus) and there are few leftover seeds of Pulsatilla alpina var. alpina, which will come attached as a gift to the first order containing other Pulsatillas.

Pulsatilla alpina ssp. alpina (large, white flowers)

 While talking Ranunculaceae seeds that need to be sown asap, I recommend to also have a look at  Adonis vernalis.

Winter getaway – Dobrogea II

, ,

Continuing the Dobrogea I with other species which call this particular and beautiful region home.
I hope you already got a taste of it; this should make it easier when growing some of these species from seeds and also help selecting the garden location.

First a mention for two endemic species:

Campanula romanica:

Campanula romanica growing on a lichen covered rock outcrop, North Dobrogea, Romania

Centaurea jankae: a species with few populations known only to exist in Romania and Bulgaria. Good luck (and broken stems by wind/animals) made it to find a few late flowers to photograph.

Centaurea jankae

Remembering the sunny days of past summer, the flowers, the rocks and wildlife:

Stachys atherocalyx, very similar with Stachys recta that I offered seeds from Carpathian Mts.

Hedysarum grandiflorum, as well just one late flowering stem was waiting to be immortalized :)

There were many other species of course; maybe more to follow when the next wave of arctic air hits us!

 

Winter getaway – Dobrogea I

, ,

Well, the trip interruption was a bit longer that I would have wished, but here we are on the road again (see first part of the trip here). In order to beat the polar vortex that descended upon us we need sun & flowers!

As I said, the drive from Southeastern Carpathians to Dobrogea region is not very long, depending on the destination it can take 4-5 hours. The Dobrogea region (with Dobrogea Plateau) in Romania is surrounded to the north and west by the Danube River and to the east by the Danube Delta and the Black Sea. Most visitors are aiming for the Black Sea sand beaches, bird watching and/or fishing in the Danube Delta, and very few aim to enjoy the particular flora of the region.

Given its position, the climate is slightly warmer and more arid than in the rest of Romania, winters are cold but with less snow and the flora is very specific with a combination of endemic plants and various species at their geographical limits. It is a special ‘meeting’ place for species of Mediterranean, Eurasian and even Caucasian origin!

Even if in late July it is very hot and dry and many species are at the end of flowering, there is still a lot to explore. I will start with a few Caryophyllaceae to keep the continuity and then show various other species.

Dianthus nardiformis is an endemic of this region and luckily being a late flowering species it was still very showy; photographed on the dry, exposed, rocky hills of Enisala fortress and everywhere else. Striking especially when dispayed against the lichens laden rocks.
Cultivated for a long time, this Dianthus makes for a good garden plant, although not as tidy (foliage speaking) as other species, but extremely floriferous, hardy and long lived. There is an impressive specimen at Montreal Botanical Garden to testify it.

Dianthus nardiformis

On the same dry, rocky hills surrounding Enisala fortress, it was a nice surprise to find Paronychia cephalotes. I have a young plant grown from seeds of Crimean accession in the rockery, and I look forward to see it flowering. However, seeing a species ‘perform’ in the wild is always much better!
It is a mat forming species with white, papery bracts posing as ‘flowers’. It is hard to think it belongs to Caryophyllaceae at a superficial look.

Paronychia cephalotes and Thymus zygioides, Dobrogea July 2017

From the neglected genus Minuartia, I will note Minuartia adenotricha, a species that you will also found on the other side of the Black Sea, on the Crimean mountains.

Minuartia adenotricha, Dobrogea 2017

Gypsophila pallasii is a similar species with G. glomerata offered in the seeds shop (as well of Crimean origin); doing very well on the dry, rocky substrate in the company of Echinops, Artemisia, Xeranthemum, Astragalus, Allium ssp. and many others.

Gypsophila pallasii at Capul Dolosman, Dobrogea 2017

A must have stop for plant lovers in Dobrogea are the Macin Mountains located in Tulcea County. These are among the oldest mountains in Europe, formed during the Hercynian orogeny with the predominant rock – granite, but also sandstone limestone. Their specific look is given by the eroded granite formations.
Although a very, very long time ago these mountains were taller than the Carpathians; today the highest point is Ţuţuiatu/Greci Peak with an elevation of 467 m above sea level.

Macin Mts., Dobrogea, Romania

In the quite dry-looking landscape of late July, Silene compacta stood apart with its rich magenta inflorescences. It is not difficult to assume that full sun locations and super good drainage would be mandatory for its successful cultivation.

Many other interesting species grow in the particular habitats of the Dobrogean plateau.

All Violas in one place

,

To finalize the query about the new Viola I was talking last week, pictures of seeds were taken (more detailed than usual): size, surface, colour, aril size and aspect are all useful characters for identification.

Viola cf. declinata seeds

Unfortunately, not having a term of comparison the identity is still uncertain. So, until I grow a few plants it will be offered as Viola cf. declinata.

While at it, why not see about other Viola spp. seeds? And, of course, why not have a Violaceae page in the Seeds Library? Have a look and notice the subtle differences between Viola renifolia and Viola macloskeyi seeds (these two native species are a bit hard to differentiate).

And how about a Viola category in the seeds shop? :)) On this occasion, I ‘discovered’ I forgot to add the Viola pubescens, as well as Viola jooi seeds to the inventory.

It’s so good to have everything in one place!

Back to normal and a Viola

,

The Seeds Shop activity is back to normal; special thanks to those who placed orders and waited patiently!

About the Viola

Last day in the Carpathian Mts. this summer was dedicated to revisiting a special place, no seeds collecting in mind, just pure enjoyment of the scenery.
Going up a narrow rock ravine to join a narrow terrace grass trail (known as “brâna”) I snapped a few pictures, which included a Viola and then kept going. On the return, I stopped to collect Aquilegia nigricans seeds and also took on the fly some from the mentioned Viola thinking it would be nice to grow it in the garden together with Polygala vulgaris, like in nature.

Viola cf. declinata, and Polygala vulgaris – Bucegi Massif, August 2017

I didn’t know on the spot which species it was, so I should have taken proper pictures for ID. But we know about ‘should and would’….
Taking into consideration the site, flowering period and flora of the region, it is very probably to be Viola declinata.
Another option is Viola tricolor subsp. saxatilis (syn. subsp. subalpina).

Close up pictures of the seeds may have a final say on this; or not…To follow…

*Allium thunbergii ‘Ozawa’ and Gentiana cruciata seeds were added to the inventory.

Winter getaway – Caryophyllaceae part I

, ,

Follow-up to Friday’s seeds – let’s go up the mountains and then travel to the Dobrogea region (close to the Black Sea, Romania) to see a few Caryophyllaceae.

I’ll start with Arenaria; yes, usually not overly ornamental plants but easy to please and cheerful when in flower. Arenaria ciliata shown below; another Arenaria found at high altitude is A. biflora.

Arenaria ciliata at about 1100 m alt.

Cerastium alpinum ssp. lanatum, the alpine mouse-ear, can be found at alpine level in quite a few mountain ranges, not only in the Carpathians; it grows on rock crevices, nooks formed between boulders, also on stabilized rock screes and alpine meadows. It is quite adaptable and the woolly foliage makes a nice addition to the large, white flowers; something good to try for any ‘not that advanced’ rock gardener (myself included).

Depending on the traveling time, there are always various Dianthus species to admire from the alpine level to the foothills of the mountain, like D. petraeus, D. tenuifolius, D. carthusianorum and D. glacialis, to mention just a few. Over the years I’ve presented and offered seeds of some of them, except D. glacialis.

Dianthus glacialis

Gypsophila petraea, a cushion forming alpine baby-breath, endemic for Carpathian Mts. usually grows on conglomerate boulders and crevices on the rock walls; often in localized areas. Excellent species for rock gardens and not difficult to grow based on from my previous experience; unfortunately, most of the capsules were immature and I found very few seeds.

Gypsophila petraea; in the image below with Asperula

Moehringia is an overlooked genus in my opinion. I like Moehringia muscosa for its fine texture and although I didn’t have a shaded rock crevice to offer, it did quite well this summer in my garden in a less than favourable position (‘protected’ by Primula sieboldii). The picture in the wild was taken in Barsei Massif (also part of Carpathian Mts.).

Moehringia muscosa

Moehringia muscosa – garden

Quite a few Minuartia species grow at alpine level and lower; among them, Minuartia verna, the spring sandwort is a rewarding, easy to grow species so don’t be shy to give it a try.

Two cushion forming species of Minuartia from the Bucegi Mts. would be worth having in a rockery: Minuartia recurva and Minuartia sedoides. Especially M. sedoides looks similar to Silene acaulis, but of course that the flowers, when present, signal the different genus. Sometimes they grow interlaced with one another and it is even harder to distinguish them.
One year I must make a special effort and collect seeds of these species.

Minuartia sedoides with yellowish flowers, Silene acaulis and rosettes of Primula minima

Minuartia recurva

I previously showed and probably everyone knows Silene acaulis (first image in the gallery). I’ve also shown with other occasion the cute Silene pusilla (now growing in my garden as well :), so please browse through the gallery to get an idea of the habitats these species are growing in (click to open full size images).

Most pictures are from the Bucegi plateau (alpine level). The ‘green’ boulders’ composed of Silene acaulis, Minuartia and other cushion species, which punctuate the barren rocky areas, are in fact small plant communities.  The cushion-type plants are colonizers of these harsh habitats on rapidly draining rocky/sandy soils, and thus very important as pioneers for the installation of other alpine species.

Here’s one more good example with Minuartia sedoides and Primula minima taking good roots in the partly decomposed cushion.

Minuartia sedoides with Primula minima

I didn’t mention Sagina, Scleranthus and probably few others but it’s time to come down the mountain. From the South-Eastern Carpathian Mts. to Dobrogea region there is about a 4 hour drive; it won’t take long to get there – stay tuned…

Friday’s Seeds – more Caryophyllaceae

,

A few images recently added to the Caryophyllaceae page on the Seeds Library – all species collected this summer in the Carpathian Mts. and Dobrogea region, Romania.
In general, species from Caryophyllaceae family are easy to grow from seeds and some (for example,  think Dianthus, Silene) may even flower in the first year.

Pictures with various Caryophyllaceae showing the habitats they grow in, will follow this weekend. Stay tuned, I’ve prepared many pictures – the time for winter getaways has come!

Easy species to grow from seeds – Edraianthus graminifolius

,

I’ve started to put together a list with species easy to grow from seeds as a way to provide info and encouragement to those who are at the beginning of their seeds adventures. The list will see additions as we go.

Let’s begin with Edraianthus graminifolius; yeah, I am not starting with A, just because I don’t feel like it :)

Edraianthus graminifolius – grassy bells belongs to the Campanula family and like its name suggests, has linear, grassy-looking leaves and large,

Edraianthus graminifolius

blue flowers, in terminal clusters in May-June. The foliage remains tight and low at about 15 cm but the flowering stems are spreading/trailing so it needs its space ;)
An absolutely delightful and easy going plant, as long as grown in full sun/well drained locations. You don’t really need a rock garden for it; just keep in mind its growth habit and place it in a suitable spot.

Growing for the first time from seeds, or just want something fast and easy? Try something from the list below. ‘Easy to grow from seeds’ means:
– easy to germinate & in large percentage
– seedlings that aren’t fussy to grow
– also, easy going plants in the garden, as long as provided with the required conditions.

I will avoid the so called two-stage germinators (although all you have to do is wait) or others that I never germinate/grow myself, species with naturally low germination rates, cases where the seedlings need special care or the ones I’m not quite sure about.

I secretly watched this globe thistle evolve from a small seedling into a beautiful clump this year; too bad I was away just when at its most glorious time. The underside of leaves and the stems are covered with a thick pubescence (shown in the featured image), a perfect adaptation for the drought; grown from seeds collected in the southern Ural Mts. (Chelyabinsk region).

Echinops crispus, July 2017

 Like in many other species from Fam. Asteraceae, some of the fruits (achenes) are empty, thus careful selecting of the seeds is necessary.

Echinops crispus fruits and seeds

Echinops name from the Greek words ‘ekhinos’ = hedgehog, sea urchin and
‘ops’ = face, head (referring to the appearance of the inflorescences)

Thursday Seedex with Asteraceae

I’m late with preparing the seedex donations; just sent a small one to the SCRG and since the local mail doesn’t take long, I’ll pack a few more for ORG & HP Society this weekend.

It’s not easy to decide what to give; I always start to think what would be more attractive from what I have surplus, then some need more cleaning than others, and so on…Speaking of cleaning, nothing is more disappointing than receiving the wonderful little packets only to find inside ‘not so good seeds’, or just parts of them (it happened a few times).

Special attention is needed to all species in Fam. Asteraceae because by as a rule some of the seeds are always empty and it is not always easy to see which ones with the naked eye; a strong hand lens is necessary.

For example, let’s look at Anthemis carpatica ssp. pyrethriformis I just prepared for ORGS & HP. This subspecies, endemic to Eastern Carpathian Mts., while bearing the same large flowers is smaller in size than the regular A. carpatica.
It is super easy to grow from seeds (warm germinator) and is a good plant for any rockery (attention when planting the grown seedlings in the garden – they need very good drainage). The seedlings shown are from a previous seed collection I did few years ago.

and the non viable ‘seeds’

Anthemis carpatica ssp. pyrethriformis – non-viable seeds; when shown already separated, it seems easy to distinguish them but actually I had to use a x 40 hand lens to do it!

Another Asteraceae donated to both SRGC and ORG & HP – Jurinea mollis seeds are shown in the featured image.

Two years in a row, instead of seeds I found in the seedex packets just the pappus of a dwarf Jurinea species (from AGS Seedex).
This is how Jurinea seeds look like, with variations depending on the species and the moment when the seeds were collected (the pappus can be reduced in size or it may have fallen out).
