Good question Barb, maybe Foxtail Lilies are just too tall when they bloom to keep in pots? Some of mine get 7-8' tall. They go dormant pretty quickly after the blooms go to seed. They do like to be on the dry side, in well drained soil. I can see any of these attributes keeping nurseries from growing them in pots.
I have been kinda getting into species Glads, and I have been playing with starting various bulb plants from seed the last few years. As a matter of fact, a friend in England sent me some species glads seeds that I started a couple of years ago. I realized after I'd started them that they are winter bloomers, which I don't really want to get into- I prefer those I can grow outside. Each winter the pot starts growing and I put them under lights. Well, to my surprise, I saw buds emerging from one this morning! I've never ordered from Silver Hills, but I believe these Glads were from leftover seed she had bought from them. They were easy to start and haven't given me any trouble.
Gosh, it would be hard to narrow down the most outstanding flowers in the yard- depends on what's blooming at the time, LOL. Foxtail Lilies do get a lot of comments and attention- most people have never seen them before. Lilies, of course, are probably the most outstanding, but that could be because there are 100s of them, LOL.
