Sorry about your losses DND. I get years like that when I lose quite a few daylilies. This year I've only lost Tropical Cooler and Lizzie's Legacy for sure. I'm waiting on several others to show themselves but I have no faith that they will. Most were struggling or new so no real surprises there.
I'm more upset about losing seedlings now than named cultivars. I lost 8 seedlings this past winter/spring. Doesn't sound like much but I don't grow out many seedlings (typically 20-30/year) so it's a significant number. Most should have bloomed this year and I was really looking forward to seeing what they looked like.
The only positive is that I'm now figuring out which parents have really good genes for my area. Gold Helmet produces very few seeds either as a pod or pollen parent. But all three seedlings from a cross with South Seas are still alive. They definitely take their plant habit from GH. My Butterscotch Ruffles crosses died but BR can have issues in the spring. Fiji is also a good parent for me so I'm hoping it will bloom this year so I can make more crosses. I have a bunch of Tropical Cooler and Lizzie's Legacy seedlings that I started this year. Time will tell how many survive until blooming!
