As part of my lily bulb buying spree from Buggycrazy, I also bought some seeds that sounded interesting:

Campanula lactiflora, Milky bellflower
and
Verbascum, YELLOW MOTH MULLEN

Apparently Verbascum is a 'weed' in the sense that it isn't hard to find, but it looks pretty and should stay in bloom thru summer.
Milky bellflower, I hope, will bring some blue into my gardening pallette since I can't count on any of my daylilies to do that !
