I almost couldn't vote also because I love all lilies so much, but the argument for hardies being easier to overwinter enabled me to vote for hardies. Of course if I lived in the tropics I probably would vote for tropicals, or just couldn't decide.
I love the characteristics of both groups and that's why I work so hard at combining them. I have at least 2 hardy x tropical cross seedlings about to put up surface leaves and more tiny plants that are VERY slow to grow from 08 seed that I've been nursing along all winter, and a couple hundred seed that haven't sprouted yet from 08.
That, along with this years seed, which are uncounted at this point, and my increased knowledge on how to get they're teeny tiny slow growing buts into gear and growing, I hopefully can mix the two groups so that we can have plants with tropical characteristics that are hardy soon. And vice versa.
