DND I've tried it with lots of different cultivars but none have taken. Probably at least a dozen. They look like they are growing well then shrivel up and die. But since the pollen is fine I have plenty of crosses with it. I'm just hoping to keep it alive long enough for it to get established. I have to redo the bed its in this Fall so that may spell it's doom.
Update: 12/30/19-I redid the bed and GS survived. I has even bloomed but I still wouldn't say it is thriving in my garden. I have since added several other near white daylilies that are much happier in my garden. I may give GS away to make room.
