Wanted to give a little brief "How To" for a certain species. It has been said that Datura quercifolia is one of the hardest Datura seeds to germinate. I have read it repeatedly stated on the internet. So I thought I'd share a few pointers...This species will not and I mean will not germinate before 30 days. It requires high moisture and warmth for germination. Therefore a medium that can be keep very moist without molding is best. Here are 2 methods I use and get almost 95% germination rate. Use
moist vermiculite (seal them in a ziplock bag) and place in a sunny windowsill. Or use damp Bounty paper towel fold the seeds inside and place them in a ziplock bag, and wait 30 days. They are also errattic. But this will give you a 95% rate. Hope this helps and Happy Gardening!
