The Snow Crystals also have those same large flowers; possibly the same critter under a different name? They are extremely fragrant, which the purple shades of Clear Crystal most definitely are not, although someone else (Joanne maybe?) mentioned that the purple ones aren't as fragrant. But I can't detect any scent at all on the purple ones I grew, so that's why I was wondering about the white. Anyone else have experience with the Clear Crystals alyssum? The price on those pelleted ones looks pretty good to me.
