Earlier this year, I did get a potted daylily from Wilds. It was a very tiny pot, about the size of a seed tray section.
I have no idea if Wilds sells tissue cultured daylily or not. I doubt they would tell you.
Daylily prices can be all over the board. Some sellers can be asking $150.00 on a plant and you'll find it elsewhere for $50.00.
I'd say it all depends on what you want to do and who the sellers are.
There have been positive and negative reports on Wilds.
I can say the plants I got from them this year have all bloomed and many set pods.
