Fresh seeds of Isopyrum thalictroides

[Karaba]

Hi,

I have some fresh wild collected seeds (~200) of the lovely  Isopyrum (=Thallictrella) thalictroides. I don't know how long they stay alive and if they can be stored, that's why I don't expect the publication of the autumn exchange lists to offer.
If anybody is interested before I sow them all, send me a PM

Isopyrum have orthodox seed so yes they can be stored "normally"

Thanks 
Should they be kept dry or moist, in the fridge or at cool temperature ? I keep my other seeds dry in the fridge.

Dry in a fridge is perfect.

In general Thalictrum and other Ranunculus seeds are said not not store well. I have had very poor or no germination from a number of Thalictrum species sown from exchange seed over several years. I have grown Isopyrum from fresh seeds. I would distribute the seeds now, or sow them and distribute the plants

Ranuculaceace seed are generally orthodox so dried and stored cold/frozen keep well for prolonged periods of time. If there are issues with viability it is to do with storage unfortunately before you've received them

I have kept some seed moist in the fridge since mid-may and 4-5 months later, all have germinated. I repot them today and will see if they are growing well next spring.
I will sow seeds kept dry this autumn and let them outside during the winter and put some other moist in the fridge so that I can have a comparison.

wonderful!

And now, the seedlings repoted last autumn are showing their first leave

How well did the dry seeds germinate, Karaba?

Hi Peter,
I have very different experience with dry seeds : it worked one time and unsucced the other one... I didn't take time to experience more and didn't harvest any seeds this year but I have some seedlings and plants from previous tries.

as I suggested at the start of this thread......
