Swamp Sunflower or Narrow leaf Sunflower, Helianthus angustifolius, can be found growing in moist, sunny areas from southern New York to Florida and west to the Ohio River valley and south to southern Texas. It can grow in the boggy piney woods of East Texas and in the roadside ditches all the way to the harsh salt environment of the Coastal Salt marshes on the Texas Coast. If planted this spring it will bloom Sept. - Nov. about the same time that the perennial Maximilian Sunflower is blooming. It is easy to tell the two apart. Swamp Sunflower has a dark purplish center and reddish purple stems and skinny willowy leaves while Maximilian Sunflower will have yellow centered flowers and larger leaves. The flowers of Swamp Sunflower are 2 to 3 inches across and are smaller than the other species in the sunflower family. Germination rate about 70% or better.
