Tag Archive for: Helleborus purpurascens

This is yet another subject that I have written about here and there; time to have all info in one place for the Germination page.

First, to emphasize again that all Helleborus are great additions to the garden: cold-hardy, reliable flowering, most are drought resistant, a variety of flower colors, evergreen foliage, plus long lived. Quite an impressive list, isn’t it?! Ah, forgot to say that they are rabbit proof, which is very important for many of us.

Considering perennial plants in general, the most ‘perennial’ among them are the Helleborus and garden peonies.  It happens that they are also the most ‘worry free’ plants when planted in the right location; coincidence?!

Back to the seeds: they mature around mid-June and belong to the category ‘catch them if you can’. Even if you walk around the garden every day, they can still take you by surprise, reason why it is best to use organza bags for capture.

Some will still ‘escape’, fall on the ground and by next spring you will be presented with many ‘baby’ Hellebore seedlings. I missed to collect the seeds from the large, purple Helleborus last year and this spring there was a carpet of seedlings underneath it! Luckily, that I found an adopting parent for them :) otherwise they would have been wasted.

This is just to emphasize that Helleborus seeds germinate easily and in high percentage – when sown at the right time!  i.e. in the summer (or fall depending on the region/country you live in).

Reason for this is that Helleborus is a member of the Ranunculaceae family (like Hepatica, Aconitum…).
All these species share the same seed characteristic: when the seeds are ripe, the embryos are immature. Germination can happen only after the embryos reach a mature stage, requiring specific temperature cycles, usually a sequence of warm/cold moist periods.

Direct sowing
We imitate nature with this well- known sowing method:  work in a fresh layer of good soil mix in the area where you want to sow (close to other plants or you can have a special garden bed for sowings), press the seeds in the soil, add a bit more soil on top and water well. That’s it.

Considering that during the summer we cannot count on rain too often, you will have to water the sowing area, otherwise do not expect any germination!

Somewhere in the spring the seedlings appear. Grow them in place for one season or more (depending on space), then move them to the desired location. They can also be transplanted at a very early stage (cotyledon stage) if needed; I did it many times and it works well.

Sowing in pots

If you have just a few seeds it is best to maximize your chances and sow in pots.
Sow the seeds like for any other species (I only recommend using a bit taller pots), and keep the pots in part-shaded or shaded location; water as needed and protect from critters. For the winter, either place the pots in a cold frame, or ‘plant’ them in the ground – an easy method for ‘winter storage’ about which we discussed many times.

Over the years I sowed various Helleborus seeds until September and they have germinated well in the spring. It means that the warm/moist period from September-late fall was long enough for the seeds requirement (embryo growth); followed afterwards by the cold/moist period (winter). Of course that this will vary depending on your location/region and where you keep the pots. In some cases sowing the seeds even later in the fall may be OK. In most parts of Canada by early November winter can arrive, reason why sowing later than September may not be a good decision.

Buying/Receiving seeds from seeds exchanges in ‘out of sowing optimal time’.
Choices are:
– Sow in pots and be patient, allowing them to naturally undergo the warm/cold periods required for germination; it may take 2+ years and certainly the germination won’t be 100%.
– Begin controlled stratification in moist vermiculite/bags: first a warm period of about  2 months (room temperature is OK) then place the bags in the fridge and keep an eye for the germination.

Yes, when grown from seeds most Helleborus cultivars or species will not all come true to the mother-plants, but the fast flowering allows selecting the best specimens, not to mention the very nice surprises that often wait for us!
They do delight us with their flowers in the spring and seem to remain in flower forever, but I really appreciate the most their foliage, so I will end the post with a picture of Helleborus purpurascens ex. Carpathian Mts. taken this month and the pot of seeds starting to germinate in 2015 (
a bit of topsoil was removed to ‘see’ the seeds germinating). They turned out really nice!

With most of the Hepatica seeds ‘out of the way’ (thank you!), we are preparing for the next wave of seeds that are best sown during the summer to ensure proper germination.

These are the Helleborus, maybe a new species this year -Pachyphragma macrophyllum, plus various native species like Sanguinaria canadensis, Asarum canadense, Erythronium grandiflorum and Jeffersonia diphylla.
All these species mature their seeds in mid to late June, and will be offered right away. I should also add to this group Pulsatilla styriaca, which in my experience also germinates best when sown fresh.

A short garden survey revealed seed pods on Helleborus ‘Cherry Blossoms’, Helleborus caucasicus, Helleborus purpurascens, Helleborus foetidus and few others H. x hybridus. Helleborus are easy to grow from seeds and start flowering in 3-4 years, your only worry will be having too many seedlings (not to mention the price of a potted plant at the garden centers nowadays!).

Stay tuned…

From the flowering front, two nice surprises: Castilleja coccinea (Indian paintbrush) is flowering for first time in the garden (seeds were sown ‘in situ’), in sync with those in the wild. Sisyrinchium mucronatum (Needle tip blue eyed grass) is no surprise, but it has a nice flowering this year, and makes a nice pair with Castilleja just like in nature.

The second flowering surprise is Delphinium nudicaule, the orange or canyon larkspur, hailing from the foothills and canyons of Sierra Nevada! Yes, it is possible. The seeds were offered in 2019, I probably sowed them in 2020/21, and here it is, flowering to the delight of the resident hummingbird and not only.
We only need to dare to grow plants from seeds!

Delphinium nudicaule flowering in June, 2023, SW Ontario

 

Just a few pictures for today. The collection of Corydalis seeds is on-going ;) and with the current heat wave it will be finished fast.
For the same reason, Paeonia japonica and Paeonia mascula are suddenly in flower and I’ll hand pollinate them to ensure the best outcome from seeds.

Various species are in flower now and it would be hard to name or show them all. Native and non-native, in harmonious combinations: Lathryus vernus in pink and violet which were shown many times, various Primula and Viola, Dicentra, Epimediums, Glaucidium…Trillium grandiflorum and Uvularia grandiflora.

A few, like Callianthemum coriandrifolium, Fritillaria collina and some Primula x polyantha of Violet Victorians strain are in flower for the first time; others are well known garden inhabitants. Helleborus purpurascens foliage has developed overnight (a very companion for ephemeral Corydalis) and Pulsatilla ex. styriaca pink is reflowering (only the seeds from the first wave will be collected).

Enjoy the spring colors!

 

Greetings to all and welcome to the busiest and most beautiful time of the year: SPRING!
We have waited, waited some more, we have prepared and now we don’t know what to start doing first.

For us seeds growers the priorities are: transplanting and acclimating the indoor seedlings AND  – yes, sowing more seeds!

Phacelia sericea, Ipomopsis rubra, Dianthus deltoides and other seedlings acclimating outdoors

Plus, keep an eye on the fall/winter sowings because many species will start to germinate at this time (newly germinated: Eremogone capillaris, Delphinium andersonii, Hepatica, Corydalis, Erythronium….)

Someone wrote to me once that he couldn’t buy certain warm germinating species because he doesn’t have indoor lights :-)

People have been growing plants from seeds long before the indoor lighting systems came into being!
Maybe there is this wrong perception because most plant addicts use them to pleasantly pass the winter time and get a jump on growing.

Otherwise, the time to normally sow the fast, easy germinating species in Northern Hemisphere is right now! Sow the seeds in pots outdoors and they will germinate with the raise in temperatures; or sow indoors and put the pots outside after the seeds have germinated (keep them protected from heavy rains, usually the space underneath the house’s eaves is a good place).

Also, various species, especially annuals and those resenting transplanting can be ‘direct’ sown in the ground. I have just sowed the other day a few more Papaver species (which are short lived) and sprinkled some Sedum atratum seeds in the rockery.

The Seeds Shop is open offering plenty of species that do not need a cold period for germination: Acinos, Draba, Dianthus, Gypsophila, Edraianthus, Silene, Papaver….to mention just a few. Watch for few new species in the Seeds List, like Rhodiola rhodantha, Silene turgida and Phacelia sericea. Just sow and watch them grow!

Also, the Lilium and Paeonia sections have been updated with the remaining seeds in stock (best to be sown in July/August when the Shop may be closed for fall Seeds List preparation).

In truth, the sowing never ends…in between, we stop to admire the result of our work :) with an emphasis on Helleborus, all seeds-growns!

 * Fresh Helleborus seeds are provided every year, when possible. When sown during the summer (in August-Sept. at the latest), they will promptly germinate in the next spring. Your only worry will be what to do with so many seedlings!

 

A favorite winter past-time for most gardeners is to review the pictures of their plants & garden while dreaming about the new season.

It is not only about dreaming though. Keeping pictures-records of your garden can serve many other purposes: use them to compare the emergence of species over the years (so you don’t have to start scratching the ground too early looking for them ;)

Also, they help to decide planting/transplanting locations for various specie: for example, too much sun exposure in early spring will hasten some species into growth, which often is not desirable in our climate. For this reason, when you have 2-3 seedlings of the same species plant them in different locations and assess afterwards which one was best (advantage for growing from seeds!).

 

Paeonia japonica specimen with shoots growing in early April, 2022; notice the flower buds! Due to the sun angle, this garden bed receives too much sun in early spring and the snow melts faster. Another specimen growing in a different location, emerges up to 2 weeks days later.


Paeonia japonica and Paeonia mascula in particular, have the tendency to emerge in late March/early April in absence of snow cover and they can grow very fast. For this reason, they are best planted in a location that remains shaded in very early spring, if possible.

Also, the pictures will show which of the early species are most resilient and useful for an early spring show; make a list and gradually add more of them to your garden.

For ephemeral species like Corydalis, Eranthis, Galanthus… it is good to take as many pictures as possible; they can later help with identification if problems arise and keeping track of interesting variants.

 

Castilleja applegatei – good germination in very early spring, after cold/moist stratification (outdoors). Later the seedlings vanished (slugs, too much or too little watering or absence of a host…).

 

When it comes to seeds germination, the pictures will serve as proof that germination occurred. It often happens that the seedlings will perish afterwards, from various reasons, and we’ll forget about them only to wonder later if they had germinated.

For gardeners in a cold, temperate climate the first timid signs of spring could appear somewhere in late March. Species with the flower buds already formed are only awaiting for a bit of warm up and the snowmelt to burst into flower: Galanthus (snowdrops), Crocus, Adonis, Iris reticulata, various Helleborus, Scilla…

The true spring only starts in April though. Even in April (and also May!), snowfalls and sudden drops in temperatures are common and unfortunately will catch various flowering species by surprise.

A few garden mementos from late March until April 20 of 2022 (on 19th it got colder and a heavy blanket of snow covered the garden).  Corydalis packzoskii, Corydalis malkensis and Corydalis solida, which also flower early, were shown with many other occasions, including in Corydalis Easter Edition 2022

 

 

The unusual warm weather experienced in SW Ontario for a while has determined many spring beauties to explode into fast growth and flowering. Then, the torrential rains arrived, and now we are heading backwards to the winter…(snow showers outside at the moment).

This is, most years, the early spring time in Ontario!

The earliest spring beauties are in flower: Lindera benzoin, Lonicera canadensis, Claytonia virginica, Caulophyllum, Hepatica americana and H. acutiloba.  Sanguinaria canadensis has almost finished flowering (depending on the region) and yesterday I noticed the first trout lilies blooming, plus Trillium erectum and T. grandiflorum with buds just about to open! The wild ginger is well on its way of carpeting the woodland floor/garden.

In the garden, few Primulas and Helleborus have been flowering for a couple of weeks now alongside Corydalis.  Other spring beauties are appearing almost on a daily basis. *Our native Primula mistassinica is in flower as well but I didn’t take a picture yet.

Young shoots of Caulophyllum thalictroides/giganteum

*Young seedlings have also appeared and some new sowings are starting to germinate.
Especially for those who have sown Caulophyllum in the ground two years ago (and the few lucky ones who received one year-old stratified seeds) –  be careful because the young shoots are dark colored (almost black) for a while and they can be easily stepped upon. Same goes for other directly sown native species in the ground, even if green colored/or sown in pots: Asarum  and Stylophorum diphyllum, Hepatica, should be germinating around this time, or soon.

 

It is always a joyful moment to see various species grown from seeds flowering for the first time. No matter if they are common or ‘rare’ species, natives or not, they bring a different feeling than those acquired from a garden center.

Flowering first time from the shaded side of the garden:

Podophyllum hexandrum (syn. Sinopodophyllum)

Podophyllum hexandrum, Himalayan mayapple

Triosteum pinnatifidum, a species grown for its beautiful foliage and fruits; the flowers are not showy but without them we wouldn’t have fruits ;)

Triosteum pinnatifidum

Lathyrus vernus, grown from own wild collected seeds, which adds to the satisfaction!

Lathyrus vernus

Other species that flowered for the first time in early spring in the shade were: Helleborus purpurascens and Pachyphragma macrophyllum.

More to come. And let’s not forget the sunny side!

The first Helleborus plants grown from seeds are set to flower this spring; knowing the ‘parents’ I cannot help having great expectations.

Helleborus x hybridus, grown from seeds of double red parents

I started to grow Helleborus from seeds just by accident really – read about the beginning in Helleborus journeying. Considering their high price on the market, it is something worth to grow yourself, especially when more than one plant is desired. And who can stop at one Helleborus?

Helleborus purpurascens grown from wild collected seeds (photo last fall) – it doesn’t seem it will flower this year but starting to look very much like its parents (see photos in the wild in Helleborus journeying)

Just like with the Epimediums, when growing Helleborus from seeds of open pollinated plants you should expect endless flower variations and many nice surprises along the way.
Not so nice surprises are also possible of course – that’s when the compost pile comes in handy ;)

There are more young plants in the pipeline: seedlings of anemone center parents (my favourites) including from H. Cherry Blossoms, various picotee forms, H. argutifolius, and the youngest of all – H. caucasicus (emerging seedlings in the featured image).

A most satisfying journey, indeed.

A short break from the deep freeze allowed me to unwrap and check the plant trays stored in the garage today. Anxiety was running high because I had noticed that a few species had started to germinate more than a week ago. Luckily, from under two sheets of fleece and plastic, the Helleborus seedlings showed their happy faces :)

While I had never thought of growing Helleborus from seeds until last year, this has proven to be a very fruitful and satisfying journey so far. The seeds have germinated promptly after being sown fresh during late summer; also the storage in moist vermiculite turned out to be a very good option for extending the fresh seeds offering period.

These Helleborus seedlings are descendants of mountaineer mother-plants:

Helleborus purpurascens

Helleborus purpurascens – a native of alpine meadows and forests in the Carpathian Mts. (Romania to Hungary)

The hybrid double Helleborus seedlings have ‘blood’ of Helleborus torquatus – a species confined to mountain regions of the former Yugoslavia (Bosnia, Croatia, Hertegovina and Serbia – where natural double forms can be found). The most desirable forms have deep violet purple flowers (H. torquatus is one of the parents of the first dark flowered Helleborus hybrids).

Double flower Helleborus torquatus

Double Helleborus torquatus

Just starting to germinate is also Helleborus foetidus, a native of mountain regions from Central and S. Europe. In many cases, Helleborus seedlings will start to flower in the second year, which is another reason to happily continue the journey. Even if not all of them will be garden worthy, there are endless chances to obtain new forms with different flower colours or traits. It will be a long time until the melting snow will allow us to enjoy the Helleborus flowering on this frozen land; until then we can rejoice in growing seedlings!

And to keep them company under the lights there is another mountain plant, this time a peony – Paeonia mlokosewitschii (a native of the Caucasus Mts.)

Update: since I wrote this post in 2014! we now have the plants grown from wild collected seeds in the Carpathian Mts. (2 different accessions) flowering well and rewarding us with seeds. Nothing is more satisfying than to see plants grown from few seeds found by chance  growing well in the garden. This species is increasingly rare in the wild; growing it in the garden it is also a matter of conservation at this point. The greenish-slate gray with back dusted purple flowers are exquisite! not to mention the foliage.

 

I am not young enough to know everything” – Oscar Wilde

A quick post because I just ‘discovered’ that Helleborus purpurascens seeds are best sown fresh in the summer. They need to go through a warm-moist period followed by cold-moist in order to germinate best. Older seeds will still germinate but in a lower percentage. Helleborus is one thing I have never done from seed (members of Ranunculaceae are notoriously difficult germinators). This is a rare Helleborus species distributed only along the Carpathian Mountains range, up to central and northern Hungary. Interestingly, it can be found growing in full sun, in open alpine meadows and also under dappled shade in beech woods.

Graham Rice, the authority in all Helleborus matters, has an extensive article on H. purpurascens on his website, you can read it HERE. In a bit of a hurry, I will quote him so no one can say I am biased because of its origins:

It is “one of the most captivating species for its engaging habit of flowering so enthusiastically, for its subtle metallic tints… The foliage too is unlike that of other hellebores, in that it radiates from the tip of the petiole in a neat circle.”

As for the flowers, a few forms that are known from Botanical Gardens: are purple in colour with dark veins, slightly pinkish towards the base and netted towards the edge; some flowers have an overall green haze…In a second form which reaches 15 in in height the flowers are smoky blue-purple in colour, darker outside than in, with slightly reddish veins inside and green nectaries. Other forms may be slate purple or deep purple outside, shining pinkish shades….”

Helleborus purpurascensHelleborus purpurascens – from what’s left it seems matching the description!

A truly collector’s plant, so this is a call for a seeds trade – if someone wishes a few fresh Helleborus purpurascens seeds to sow them right away, please get in touch with me here, on my email or at infoATbotanicallyinclined.org (of course replace AT with @

It would be a pity not to have them all germinating well – still enough summertime left!
