The ones for the Dutch industry are mainly for cut flowers, it seems. And for that, they have a certain uniform shape to them. I was so enthralled when I first saw some of the ones I bought from The Lily Garden. It looked like butterflies were floating around in the garden, so delicate looking. I like the Dutch ones too. All lilies have a place.
Sounds like you're going to have some work to do. Astilbes can surprise you with how much sun they can take if they are really well mulched.
I remember seeing the pictures of your garden beds, Sally. They are lovely. I started mine all about the same time, and I just noticed this year they are getting really crowded. So in the next couple of years I'm going to be doing some major overhauls.
