I have grown the most common cultivar of this species in my se PA yard of 'Fireworks', which is really nice. I finally saw the straight species close to the "Meadow" of Longwood Gardens in se Pennsylvania in early October of 2014. It looks good, just less pendulous than the cultivar. It is also an easy perennial, needing little care.

A very common wildflowers along the roadsides and waste places of Newfoundland. A bit weedy for a formal garden but ideal for a wildflower garden. The flowers are very attractive to butterflies. There are several named, more-tamed selections derived from this wild species.
