It's been four years since I started to make a raingarden out of a wet corner of the backyard. The first plants stuck into that mucky mess were blue flag irises (Iris versicolor). Winter, summer, spring, fall: there has always been plenty of green spiky iris foliage but never, ever, any flowers. This spring, I was becoming so exasperated with the lack of bloom performance that I was wondering exactly how bad it would be if I replaced these blue flags with yellow iris (Iris pseudacorus). Yes, my line of thinking/rationalization went, yellow iris is listed as an invasive by the USDA and prohibited as a noxious weed in Massachusetts, but they look so lovely blooming in May and June along the margin of our town pond. So, if yellow irises are flourishing on town property, how bad could they really be?
Thankfully, I was saved from sliding down that slippery slope by a single blossom. At last, the blue flag sent up a flower. And it is beautiful. So, no doubt, this iris wins a reprieve.
