Summary

Swamp sunflower is a tall, striking plant for the perennial border or naturalistic meadow garden. Bright yellow, 2½” daisy-like flowers grow on 6’ stems clothed in rich green needle-like leathery foliage. The clusters of flowers standout when viewed at a distance or close up. Helianthus angustifolius lives in a wide range of soil moisture conditions.  Swamp sunflower is special because it is among the last plants to bloom in late autumn. This sun loving perennial grows well among Schizachyrium scoparium, Andropogon virginicus, Symphyotrichum georgianum, Symphyotrichum oblongifolium, and Euthamia caroliniana.
