This is not a good picture of the diploid Hakuna Matata, it is a beautiful lavender color (not sure why my pics in the database look like they do), but it is one of the sturdiest in my garden and gets about 4 feet tall. Plus it has very good branching, as you can see in the picture, and it blooms mid to late-July when other daylilies have waned.
I fell in love with it a few years ago in a sellers garden, had already overspent that day, but just knew I had to have this one! So glad that I got it
Cindy said Indian Giver and Diana mentioned Raspberry Wine. I have both and they are good ones. The scapes are not too thick, but they definitely stand up. And Raspberry Wine is a bud builder in my garden. Other dips that I have that I think hold themselves up well are: Lavender Blue Baby (parent of Hakuna Matata), James River Rose, Savannah Debutante, and Jean Swann, to name a few.
Definitely would not include Noel Weston in this group. I don't think it has ever had a scape stand up in my garden. Why in the world I have had it for going on 9 years, I do not know!
