The native Pickerel Weed is an aquatic perennial that likes full to partial sun and shallow water or wet mucky soil. It is about 1-3' tall, consisting of a loose clump of basal leaves and occasional flowering stalks. The long-stemmed basal leaves are smooth, lance- or oval-shaped, toothless and up to 7" long and 5" across across. The stout unbranched flowering stalks are 1-3' long, hairless, hollow, and terminate in a floral spike up to 5" long. The brilliant blue-violet 3-petal flowers (up to ½" across) are densely arranged around the spike.
