Neal, I planted 6 of them in the spring. I found them cheap in a grocery store and they were supposed to be E. stenophyllus, but turned out to be a mix also including Ruiter hybrids. In this case I didn't mind at all
I also tried one planted in the fall, bought from a "proper" source, but that one was much smaller and took two years to bloom! To be fair it was a good price on that one as well, so couldn't really ask for more.
Edit - of course not all 6 were Ruiter hybrids. Some were E. stenophyllus as they were supposed to be.
