Hemerocallis lilioasphodelus the so-called Lemon Lily this daylily species is also quite early although consistently blooming after Hemerocallis dumortieri and Hemerocallis middendorfii. The color is a clear lemon yellow and has a distinct fragrance. This daylily has a somewhat spreading habit but is a slow grower here in Vermont. One of the first daylilies introduced into the U. S., it is sometimes found near old abandoned cellar holes, a testament to daylily's longevity. Hem.lilioasphodelus was originally called Hem flava referring to it's lemony scent. The spreading habit is not particularly vigorous and so creates loose clumps. Hem lilioasphodelus seems to prefer a damper location as well.
