Meanie, the seeds don't have to be really fresh. They germinate like cress - warm germinators and need light
Interesting. I've tried several times before and failed. This time the pod was given to me last summer but I forgot about it till December'ish. So they were sown and placed in a sheltered spot outdoors.

Gabriella, when did you sow the J. diphylla? I sowed some fresh seeds last summer but they have not germinated yet. We did not have a very cold winter - just a few frosty nights, not much below 0C, I wonder of that is why the seeds failed to germinate? Unfortunately the parent plant - which I only bought last year, also failed to come up. It was planted in a woodland area with trilliums, erythroniums etc, so the right sort of habitat, I imagine. Looks as if I am destined not to be able to enjoy these beautiful flowers.

Carolyn – I sowed Jeffersonia on 28 Nov.; after collecting, the seeds were kept in slightly moist vermiculite +/- outdoor temp., like I do with most early summer collections. I never have time to sow them right away and there are still overflow pots from spring to deal with.
With many NA spring flowering species, which have immature embryos when the seeds are ready, the problem is not the cold period that they receive, as the common belief goes. They require a certain pattern of warm/cold, and if it’s not appropriate, the embryos remain under-developed and will need another warm/cold period to grow and then germinate (keep your pot).

For  Jeffersonia diphylla it has been found that the embryos need a period at about 28˚C in order to elongate and only afterwards a cold period (4˚C , fridge- like is enough). If they enter the cold period though before reaching a certain size, they will stop growing and need one more cycle warm/cold.

So, in some years the problem is a cold summer actually, which may be your case? And this applies not only to Jeffersonia.
On the contrary, for other species like Hepatica, summer temperatures over 25˚C, can induce the embryos to stagnate in growth.

Fascinating, isn’t it? Sorry I made the answer a bit too long. I hope I’ll have more seeds this year, and it seems warmth won’t be a problem here ;)

Thanks Gabriella, I think you have found the answer. Last "summer" the temperature was about 14 - 16C on most days, and on only a very few days reached 20C. I think I'll put the seed pots in the greenhouse over the summer. Come to think of it, there were some pots of fresh trillium seed which I expected to germinate this spring, but they didn't - probably the cold summer too. I usually keep pots for several years anyway - have just had a nice germination of sanguinaria, sown 2010! And iris hookeriana, sown 2012.
Anyway, we have lovely warm sunshine here this weekend, which is lucky, as we have the garden open for charity. We had lots of visitors yesterday, just in time for the sumptuous meconopsis. There are some advantages to living in a cool damp place!

A nice surprise yesterday when looking over my a bit neglected seedlings at this time - Trientalis borealis with what it seems like 100% germination.
From a batch of older seeds (2013) - my label says that I gave them a GA3 treatment at the end of January, and put them outside over the winter.

Ophiopogon umbraticola
I only had nine fresh seeds to work with, so I remove the pericarp of four berries before planting (right pot), and left five intact (left pot).  Since I am not sure if the species is winter hardy here, they went into the fridge Nov 17, and came out April 10, almost 4 months.  The separated ones emerged in 15 days, the others are just now emerging, 46 days later.

Here are some seeds that have started to germinate, first is Lillium Formosanum Pricei, can't remember where I got the seed from. The next one is narcissus Bulbocodium, these are rhs wisley seed, I was at wisley last spring for the cyclamen society show and they had a grassy bank full of these, a really beautiful site.

I posted the above item in March last year, the other day I was checking over the L. formosanum pricei and I was surprised to see flower buds on all three plants that had germinated, is this species normally this fast to reach flowering size?

Hi John, yes I think this lily is well known for being very quick from seed. Unfortunately I think it is rather virus prone so it is best to resow regularly so you always have fresh stock.

Best, Tristan

Cheers Tristan for the information, I'll make sure I collect some seed. Good luck for Wales tomorrow.

Here are some seedlings I'm pretty excited about - Thermopsis barbata, from Bjornar's seed (trillium.no).



An update on this one. I was convinced they had all rotted off over winter, but all have emerged now - very late, one is still only just above ground. They are still very small, but still alive at least. I've now planted them all out where they will hopefully establish. Not expecting flowers anytime soon though!
