I think many of them can take full sun. I have 'Ballerina' in full sun, it blooms really well and the plant looks nice. Some varieties like more shade than others. Which ones were you thinking of trying?

Thanks for your input - Johnson's Blue was on my list as well, so I am feeling better about my choices now. I like the look of 'Biokova' but I think someone mentioned it taking over? I wanted something that would stay relatively tidy and not spread super-fast. Need something short-ish (and long-blooming hopefully) for the front of the bed to hide tulips and daffs when they get yucky. Colorwise, anything pale pink, white, or light/medium blue would work. Was also thinking about Dianthus or Scabiosa...any thoughts on those? I am open to any other suggestions in these colors since I am new to perennials. Thanks!
