Julia, it has been interesting. But now I'm in danger of becoming a Sedum junkie. But when I see photos people post of what's available in their local nurseries and even big box stores, it makes me wonder. The Ogon, Sea Urchin, and Florida Friendly Gold are all I've seen available here, so a lot of the really exciting clones might not survive our hot, wet summers. Too slow-growing to be useful as cool-season annuals!
Greg, I've had a lot of experience over the years, but I'm surely no expert. It has been quite a mixed bag, and I've certainly killed more seed than I've "hatched"! Just look at all the Sedum seedlings I've killed. Here's a photo of last year's seedlings:
So disappointing that with all that to start with, I ended up after damp-off, etc., with only eight plants. My bad! Lots fewer seedlings this year, but with a bit of experience behind me, I hope to end up with more than eight new plants.
So, all I can say is... Go for it!
