Some of my seeds are sprouting after only one day. This method with the moist paper towels is awesome! Especially when combined with a hot pad — things can happen quickly. The white coneflowers are definitely sprouting — several had little “tails” poking out. And they’re supposed to take 10-21 days to germinate.
The cosmos are starting, but I only saw one actual sprout in my quick look. I also think the Salvia transylvanica are just getting started, but the seeds are so tiny, it’s hard to tell. The Salvia nemorosa seeds all have secreted a little clear sticky stuff around them, which is a precursor to germination.
The California poppies and the Coreopsis are not on the hot pad, and I don’t see anything happening yet with them. I might put them on the pad in a few days, but they don’t need as much heat as the others.
