Starting Gentian Acaulis

Hi, has anyone started this from seed? I bought a seed packet when I traveled for work to Europe, but I don't understand the language(s) used in the instruction. If you could ID the language that would be greatly appreciated.

I posted the question in the perennial forum. To avoid duplication, here is the link:

If not moist packed, these are generally best sown very fresh. "sow seed from the species as soon as it is ripe - waiting too long causes slow, erratic germination" If your seeds are packaged dry, by all means still try but you might cover the seeds with a bit of grit instead of more of the sowing medium, will discourage moss and algae on those pots that may be with you for a while.

Warm, cold, cool germinator. Sow at 64-71F for 2-4 wks, move to 39F for 4-6 wks, move to 41-53F for germination. Cover thinly, some light may be beneficial to germination.

Thanks, morz! It sounds a little complicated, but I am going to give it a try. Nothing to lose anyway.

Not really complicated, think about the conditions the seed would be exposed to if it had fallen from the plant when ripe....warmish Fall, cold winter, cool late winter/early Spring. You're trying to mimic that which mother nature would have done but artificially and with shorter temperature periods.

Morz8, right now I put the seeds in the refrigerator to mimic fall. Do you think after a while I need to freeze them to mimic winter?

No, I think you need to take them out of the refrigerator and leave them at room temp for 2 - 4 weeks to mimic Fall...still warmish and rains have started. (First: 64-71F for 2-4 wks)

Then put them into the refer. Approx 40F is cold enough, very few seeds need to actually freeze, most will not be going through the conditioning process until they are not quite so cold so don't use your freezer.

The third stage is the one that is difficult for me indoors...I don't have a good place to achieve that 50ishF range and have to try to time it for late winter-earliest Spring here when I can put the pots outside.
