This is a highly variable species with a number of showy cultivars, though wild forms of this plant do not seem to be all that spectacular. All images taken in southern NJ. The plants in the first two images are likely var. elodes with narrow lanceolate leaves that scarcely clasp the stem. The plants in the last three images, taken at a nearby location, appear to be typical S. novi-belgii with wider, more oblong leaves that clasp the stem at the base.
