I came here because I saw 'Blue Eyed Butterfly' listed as Plant of the Day. I was contemplating whether to file a performance report or just post in the thread.
I think 'Blue Eyed Butterfly' is the only Lambertson I grew (so my input is very little), but I don't catalog my daylilies that way, and the manner I would have to search would be too tiresome to see if I have other Lambertson daylilies.
As for 'Blue Eyed Butterfly', it did fine for me upon planting, and that was probably in 2003 based on one photo. The plant increased and bloomed nicely every year. But then, I think it was the winter 2014-2015, that I lost the entire mature clump. I did a waah waah because I really liked it. I lost 2 other plants at that same time, but they were evergreen foliage type daylilies. This loss was because in March or April, actually spring, we had a great warm-up period. This sent a lot of perennials into new growth. Then, in April, we had a *hard* freeze.
