I always thought it was common knowledge that you could grow a daylily from one of the small tubers attached to the crown but apparently its not. This is something I have been doing over a LONG time now. I mean literally over a decade. If I see a daylily I will ask if I can take a single tuber from the plant. I plant that tuber and it always grows into a new daylily plant. Its never failed me. I have actually had people arguing about this lately insisting that tubers won't grow by themselves. I've got 7 of them out by the shed that I got from a vacant house while we were visiting Ohio last year. Half of them even bloomed this year.Yet lately I have had big arguments with people insisting this won't work. Apparently I'm going to have to document it.
