Q.What To Do If Larkspur Sprouts In Late Fall
I grew larkspur this year for the first time in my garden. When the seed pods began to turn brown end of this summer, I tried to collect them for next spring, but understandably the plants had already dropped some as has become plane to me now, unfortunately. We live in Jeju SK and though it has grown pretty chilly lately, sunny days can still get into the upper 50s to lower 60s and then there has been some rain lately. I have been informed that larkspur requires a period of cold stratification for ideal percentage of germination, but this morning I went out to the garden and found the spit image of larkspur seedlings, and quite a few of them. This seems rather long-winded but I wished to give some context and if you could kindly inform me of any way to save these seedlings over the winter, I would be much obliged, though there doesn’t seem much hope as far as I can see.

Unfortunately, they are probably at a loss for this season. They will not tolerate being moved, and will not survive too long into colder weather. I would say that you will have seedlings come up in the spring, however.

Thanks for answering so quickly. It's an awful pity nothing is to be done but all the same, I'm glad to know for sure and I suppose I'll just re-sow come spring. Thanks again
