Sometimes when I order irises, or see vendors photos, it is during the warm days of summer and sweet yellow or lovely purple little blooms look so enticing. I now have about 30 different SDB's in a shade of purple and maybe as many in yellow. I like them but they do compete, and look quite ordinary, with all the daffodils and crocus that emerge during their bloom time. Each summer i tell myself not to get another purple iris.... that being said they are introducing a couple of purple SDB's this year that i really want.
While on a quest to find a blue TB iris i acquired quite a few lovely pale purple irises and seeking a black TB i have added quite a few dark purple ones. I need to choose which needs to go. Once you look at an iris and think (ho hum) that its lovely but much like another then it is time to make some decisions. Most of my irises make me want to dance in the garden and those are the ones i love.
(edited to add) Also.... if it falls over in the least wind, turns to soggy lumps in a rain shower, does not bloom no matter what you do.....
