Pink sunglasses

Winter is a black & white season in this part of the Northern Hemisphere. I patiently await for the invention of suitable glasses that would project on my retina sunny, flowery images all day long.

Meanwhile, I use my indoor light stand as an indoor garden. It is bright and I get to wear sunglasses that adjust to my desired colour*. Today I have chosen pink for Incarvillea (various species, all commonly called Incarvillea or hardy gloxinia).

Hardy gloxinia species belong to the so called ‘warm germinators’ (will germinate at room temp.). They are also easy to grow indoors and, like many other tuberous species, will benefit from an early start, having more time to develop a good size tuber by late spring when they can be planted outside. Some may even flower in the first year, like it happened with I. delavayi. I have already grown from seeds I. delavayi and I. zhongdianensis.

Incarvillea zhongdianensis, a mature plant, not in my garden but I expect my first flowers this year :)

This year I am happy to start two other species: I. mairei and I. younghusbandii. These are smaller species height-wise, the second a real dwarf, but with larger deep pink/magenta flowers; this combination gives them an even more exotic look for our Northern Hemisphere gardens.

Looking at the world through pink sunglasses in late January is pretty amazing!
Then, there will be days for yellows, blues in many shades, purple, orange…

*Such sunglasses of course, do not exist; except in my imagination.

Here’s a very, very short list of others ‘warm germinators’ that can be started early and will grow well under lights indoors.
Anthemis, Arisaema,
Astragalus, Anthyllis
Anthirrhinum, Iris*
Biscutella, Calycanthus
Oxytropis, Sanguisorba, Roscoea
Scabiosa, Hypericum, Physochlaina
Draba, Allysum
Campanula*, Dianthus*, Lilium*
Agastache, Primula*,
* not all

also, see update from Feb.8

How the moist stored seeds of C. nobilis are looking at the moment. This is the first time I have ‘excess’ seeds and it is interesting to see how they ‘behave’.

The growth of the embryos has resulted in the expansion of the endosperm and splitting of the seed coat. This is not happening in many species and has been reported as well in Corydalis ambigua; I also noted it in Hydrastis canadensis last year (see below).

Corydalis nobilis seeds with enlarged endosperms (January – seeds in moist storage)

Hydrastis

Hydrastis canadensis seeds with split seed coats by early January (germination in April)

These type of seeds, which have an undeveloped embryo when ripen, require warm stratification before embryo growth can occur in late autumn. The root emergence, followed shortly by the cotyledons, will happen then in early spring (somewhere in mid-March-April).

If I’m not wrong, that’s when I expect to see the ‘little lords’ showing up!

UPDATE – Feb.8

I was wrong! – by second week of February I spotted the first radicles!

Corydalis nobilis – germination start

It continues to be very gloomy here, so a bright and sunny picture will do us all good :) And, I repeat again because not many are mentioning; besides being very hardy and beautiful, the lord of the Corydalis is also fragrant!

Corydalis nobilis

Warning!
Germination of Corydalis nobilis from dry seeds is so poor (not to call it non-existent), that’s not even worth trying it.

Friday’s Seeds – Asparagaceae

Keep up the pace!

Another benefit of organizing the seeds images after their respective family is that I get to update my files regarding changes that have been made. And there have been quite a few lately.
For example, Fam. Asparagaceae includes now many of the formerly Liliaceae genera such as Maianthemum and Polygonatum. Also Scilla, Hyacinthella, Muscari, Ornithogalum, together with Yucca, Agave and many others are now part of the largely expanded ‘Asparagus’ family ;)

Change can be hard but got to keep up the pace. Just a couple of Scilla and Ornithogalum species which are new for me.

Talking seeds, this is a good occasion to point out at my new website feature –

Surprise, surprise! – Iris pumila

Growing from seeds is always full of surprises, especially for first time sowings, like in this case for Iris pumila.

Iris pumila – a dwarf, early spring flowering, bearded Iris with a wild distribution from Central Europe to the Caucasus. The large flowers can be violet, blue, purple, yellow, or in various combinations like it naturally happens in wild populations; it is super hardy and excellent for the rockery, or a sunny border.

For best germination, most sources suggest soaking the seeds and providing about 4 weeks warm and then a longer (few months) cold period. So, my plan was to keep the sowings the furnace room for 3-4 weeks (+/- 23C day/ 17C night) and then place the pots outside under snow for the remaining of the winter. I sowed on Dec. 19th – and a couple of days ago (Jan. 5)…surprise! I found some pots with the first shoots were out. The plan has changed of course, and my light stand will be up very soon :)

Iris pumila – seeds soaked, sown on Dec.19th at warm – first signs of germination Jan. 5th (few even sooner)

The pots contain seeds of differently coloured specimens, although this little Iris can provide even more surprises colour-wise!

I don’t know if the seeds will germinate in the same way after going into a deeper dormancy, but this is still a good time to sow – and few fresh seeds are still available in the shop!

A walk through the Finnerty Gardens

In the idea of opening the New Year with a colourful post, I will show a few images from a small but charming garden seen in Victoria (Vancouver Island).

The Finnerty Gardens, located on the grounds of Univ. of Victoria, came into being as a result of the Buchanan family estate donation to the university. At their property in Lake Cowichan, Mrs. J. Buchanan Simpson and her husband developed over the years a large collection of Rhododendrons, mostly grown from seeds; when it became impossible to manage the collection, Mrs. Buchanan made the right decision.

Although it is not a botanical garden, many species have signs with the names, and besides the large number of rhododendrons and azaleas, there are many other interesting plants displayed in an enchanting woodland atmosphere. Among most notable: a large Davidia involucrata tree, Magnolia species, Styrax japonicus, Michelia, Camellia, a stumpery with lots of ferns, and also native species of the region like Vancouveria hexandra and Dicentra formosa.

An absolutely delightful place, I hope the colors will make it up for the lack of sun – click to enter the gallery and enjoy the short walk!

 

Entrance is free, parking also free on the weekends.
