Flowers & seeds of June

,

Sanguinaria canadensis (bloodroot), first seeds of 2023

It is already mid-June, wow! This is the time when various spring flowering species start to mature their seeds; soon there will be a wave of native species seeds one after another starting with Sanguinaria canadensis, Asarum canadense, Stylophorum diphyllum, and Jeffersonia diphylla…to mention just a few.

Various other species mature their fruits gradually, and also the collecting is done in the same way. For most Viola species, Silene pusilla, Saxifraga cuneifolia, Capnoides sempervirens…this involves seeds collecting every day now. Plus, Helleborus caucasicus seeds are being captured by organza bags, and others will follow shortly.

As soon as there is a larger batch of species collected, there will be another call for seeds, probably in late June – stay tuned.

The regulars of June garden are in flower now: Dictamnus albus, Baptisia australis, Clematis integrifolia, various Dianthus, Salvia, Aconitum moldavicum, with Asphodeline lutea in top bloom. While we all rejoiced in few rainy days, it was not very inducing for taking many new pictures. There are also new garden friends this year, like Glaucium aurantiacum and Gladiolus tenuis.

Incarvillea delavayi

This is also a good time for planting 2 years-old seedlings of various bulbous species in the ground, as they enter their summer rest period.

Erythronium sibiricum 2 years-old tubers before planting in the ground

Species like Corydalis solida and allies, Erythronium, Fritillaria, Adonis, Crocus species, Galanthus…you can plant them in the ground after the second year of growth. They can also be grown further in pots, but honestly, I have obtained better results for  such species with this method then by growing them longer in pots. The Canadian plant trade is lacking diversity for these species, so what can we do?

We grow from seeds!

Jeffersonia and Trillium anyone?

,

With many thanks to the owner of the well known by now Aspen Grove Garden (Guelph, ON), who collected and successfully tried a new method for storing hydrophilic seeds, we can continue to indulge in Jeffersonia diphylla seeds.

This lovely (and rather rare in Canada) North American native species doesn’t fit the profile for mass propagation. So, here is the chance to grow it for yourself from moist kept seeds, and give it a home in your garden. True that it takes 3-4 years until reaching flowering age but what a joy to see it starting to grow and flowering every spring afterwards.  I will make it a big event when my first seedlings will flower (next year I hope :)

Not too many seeds available this season; for many spring flowering species the pollination has been affected in our region by the very cold weather. Do not wait too long!

Also, we can relax a bit about Trillium grandiflorum. I managed to collect not too many seeds and luckily now there are more.
Do not relax for too long though because, as I showed every year, most of these seeds will start to germinate (little tuber/root) somewhere in September and after that shipping is not possible anymore.

Trillium grandiflorum fresh seeds 2019; most of these seeds will start to germinate (tuber/root only) somewhere in September/early October! like shown in the picture below

Trillium grandiflorum germinated seeds after a first warm cycle; the first leaves will grow after a cold cycle (ie. winter); part of the seeds will only germinate in the second year after sowing

There is plenty to read on this website about growing Jeffersonia and Trillium from seeds, I’ll leave you to the readings :)

We’ll talk later about how to easily keep hydrophilic seeds in good condition for a few months without bothering with Ziploc bags and moist vermiculite.

PS. Caulophyllum thalictroides mix seeds also in stock!

Friday’s Seed – Jeffersonia diphylla

, ,

During a visit to the Aspen Groves Gardens to leave a few of my ‘precious’ seedlings for babysitting, I have also been ‘presented’ with nice, fresh and fat seeds of Jeffersonia diphylla :)

The seeds don’t keep very well in moist storage and I will be trying a new method this year, but you may never know how it goes…I recommend to those who have been waiting for it, to get hold of the seeds right now (orders are accepted until July 12th, then the Shop will be closed till August 10th).

And btw, those living in driving distance from Guelph, Ontario – this Saturday, July 8, Aspen Grove Gardens of Robert and Judy Pavlis are open for visiting from 10 am- 4 pm.  Don’t miss the opportunity!

Note: Besides sowing fresh or moist kept seeds, I emphasize again the requirement for good germination.

Baskin & Baskin have shown that ripe seeds of Jeffersonia diphylla have an underdeveloped embryo. Seeds need high summer temperatures (30˚C) in order for the embryo to develop optimally and reach at least one mm in length before dormancy can be broken by cold stratification. If this requirement is not met, another warm/cold cycle is required by the seeds to germinate.
