Sneezeweed is a native plant in the aster family found growing throughout North America in areas with damp meadows or rich woodlands. Growing 3' to 5' tall, it makes a formidable statement in the back of a garden border. Pretty yellow ray flowers that are about two inches in diameter and have yellow to brown centers bloom from late summer into the fall. Each petal has three notches at the tip and droops downward from the bottom of the globular disc. All told, they last about two months. It can also be identified by the deeply ridged or winged stems and narrow, alternate leaves. In spite of its common name, this species is not known to cause sneezing or allergies. Sneezeweed is a wonderful sun-loving native plant.
