Flora North America notes that pink-suffused D. cucullaria are common, but noticeably pink forms are rare in these parts. This spring in the nearby woods I found (and marked for later reference) a clump with quite definitely pale-pink flowers. The same woods also has a colony of D. cucullaria which have pink-blotched white flowers. You can find a lot of other variants of this species in such characteristics as flower size; the length and angle of the basal spurs; the number of flowers per scape; the amount of yellow at the flowers' apex, etc. I've never heard of the cultivar 'Pittsburgh'. Leaf color also shows quite a bit of variation in the two native dicentras. Some populations -- particularly of D. canadensis -- have extremely glaucous foliage. So far this spring the star of the local wildflower show has been Erythronium americanum. For some reason, at least twice as many are in flower this year as in any other spring in my memory.
