This spring will be a true test for some things lily. It's a good thing I don't show lilies or I might be crying.
My Red Velvet and Tiger Babies proved so far, to be stellar. Neither of them had bad signs from late frost after to much warmth in March. I will say that Karen North seems to look shorter than normal. And as far as the true L. lankongense, it has never lasted more than one season here. Why? Who knows. But the L. lankongense relatives from Judith's collection, all seem to have done well. And my Peach Lace bulbs twice now, have appeared far (1-1/2 feet) from where I have placed their signage, which means they have "wondered" for me too. Ariadne looks good too, as do my other North Hybrids.
On the other hand, I have some OTs that have really taken a hit with this weather. These are supposed to be more weather tolerant. I never know what exactly the problem is, how far into growth they are when the freeze hits, hardly any snow cover( I don't think that's it, as they all looked good at first coming up). It could be anything, it could be everything.
