Maurice - I have actually done what you suggested. And it does work fairly well. I live in a neighborhood on a quarter acre lot which includes the house in the middle of the lot. I don't have a lot of room for very many decent sized pots within a pot. Space, heat zone, and nematodes are my challenges to growing daylilies. I grow so many other plants that I really thought that daylilies would be just as successful when I first started growing them. After about 3 years, I started to realize how challenging it was to grow them long term. And with none of the local plant nurseries selling any kind of daylily, I started to catch on that daylilies struggle here. But I continue to grow them (mainly seedlings now from seeds) because I do enjoy them, even if for a year or two until they perish. I consider most of them annuals and am happy if I get blooms before they die. They are truly beautiful blooming plants!
I do have another question .... which ploidy typically produces the most seeds from a pod? A dip or a tet?
And does anyone have any diploid parents they recommend to use in crosses?
