Collecting Hosta Seeds: Update (2 years later)

As the summer heat continues, I have been diligently looking after some of my strategically placed baby Hostas - which I grew from seed (link to previous post here).

Two years ago, the above seedlings were just setting root in mid summer and I transplanted them into tiny pots. Come autumn, I tucked them in sheltered spots of our garden where I would find them again.

Having planted them all over the garden, I've been making sure in this heat to keep them moist.

Still super small, they are putting on some lovely growth. The above is my best sample. 7 leaves and still more emerging.

This one above is situated in our herb garden. I was testing to see if more organic matter and compost tea make a difference.

The leaves are surprisingly tough. Quite slug resistant. The original parent had leathery leaves too, but with deep yellow variegated margins.

None are showing any venation or variegation. But that's ok. For now they are doing great, considering I haven't done much.

In all honesty, if I really wanted these Hostas to thrive and grow quickly, I would of left them to grow in pots and nurture them more. But reality dictates little time and so finding spots where I know I can keep a close eye on them seems to have been the best bet.

I am anxious to see their eventual mature size. I've noticed the above photo has more rounded leaves. Who knows, I may have a "Heidi Horticulture" hybrid developing! Ha!

Collecting Hosta Seeds: The Experiment

I have several hostas in my little garden. I love them. This one is 'June'.

Endless divisions have made my garden fuller and other folks happy. Yet, I have never attempted to germinate them from seed. Knowing their seed won't be like the parent plant, I still aim to try the attempt. I realize this may be a waste of time, yet - I'm itching to see if it works out. My garden is small enough to contain about 6 various hostas that flower at the same time. I want to see if cross-pollination has been successful. Late last summer, I witnessed wasps and bees go from one flower to another. Now let's see if I can grow some from seed.

Throughout September and October, I began to harvest the seed.

I waited to collect, until the seeds had matured on the stem.

This Hosta plantagenia has rather long seed pods, full of seeds.

Be sure to harvest the seed when the pods are beginning to dry out and turn like straw - just before the pods begin to spring open. Lay them out on a piece of paper for a few days to completely dry. Then mark an envelope for each variety.

Several pods have duds - these pale white seeds that have no embroinic component. Discard. Like maple keys, they have a winged portion and a seed tucked in the tip.

They look sort of like tadpoles. The trick to germination, is stratification when it comes to hostas. I learned this the hard way. My first attempt had zero results. The second attempt after stratifying the seeds, worked. This means, they must be cooled in storage before sowing. I left them in their little envelopes, in a sealed dry container in my little potting shed - outside all winter. The stratification initiates the seed to germinate. The potting shed gets freezing temps which help the seed to become ready for germination. The key is to keep them dry. I just placed them in paper envelopes and in a tin box.

In May, I gathered some toilet loo-rolls for this:

Cutting toilet rolls in half, I filled them with potting mix. Compacting the soil tightly in the rolls. Once the rolls are watered they can swell and fall apart, so I use string to keep them grouped. Here I just used stuff around the house. I only had enough viable seeds to fill 16 half rolls. This old baking tray will do the trick.

I examined each seed. Making sure they had a wing and a solid seed side. Taking the seed I placed them on the surface of the potting mix.

I put about 3 seeds per roll.

With the blunt end of a skewer, I tucked them in just beneath the soil's surface.

I marked each roll with a dot, differentiating between the varieties of hosta seeds I collected.

I tied them together, so they don't collapse as easily.

To add greater humidity, I made a tiny greenhouse tent. Sticking skewers into the rolls, I have made posts for the cover.

Until germination, I just want to hold in moisture and humidity. You can buy seeding trays with domes for this purpose, I just decided to use household items for the job.

I placed it in a warm window sill, in late May until the threat of frost was over.  Bringing it outside to help the process.

Within 4 weeks, this is the result:

Small little hostas emerged.

I thinned out the germinated plants, leaving the stronger, healthier baby hostas - 1 per each roll.

Within 4 weeks, they are now starting to look like mini hostas. Once they begin to show a second or third leaf, I lightly fertilized them with a 7-7-7 water soluble. No streaking or colouring, yet. Plain green as I suspected. Who knows...it may still happen.

Once they fill out these rolls, I will transplant into larger pots and see what nature reveals. Will update later in the summer. It certainly is a fun process. But if you want to guarantee true cultivar characteristics, then divide from the parent plant you like.
