I don't have 50 different varieties; I ordered 3-5 each of a few different ones. Silk Road has been my favorite, with Robina as a close second, because it has such strong, sturdy stems and such intense coloring! It is as tall as Silk Road, but doesn't need to be staked!
I need to add some others, though. I have some "color gaps" that lilies would fill nicely.
