Yes, they're all pretty when they're blooming and at the same time, each is beautiful in their own unique way. I don't really have a favorite---I like them all. But I do have a higher appreciation for some than I do for others. That is, from the standpoint that it takes more than a pretty flower to make a beautiful plant. To me, everything about a plant must come together in perfect harmony, it's height, it's foliage, it's inflorescence, pedicel length, angle and spacing, reasonable bud count and flower size all must be in proportion to compliment each other---and it must be carefree and garden hardy. With that in mind, my choice is 'Seafarer'. They say beauty is always in the eyes of the beholder in different ways, but the way I see it, Seafarer represents a very high level of hybridizing achievement. So, I guess, if we could somehow translate appreciation into favorite as being the same, then Seafarer would be my favorite.
