Pontederia cordata

Pickerel Weed

Perennials, Aquatic, Flowers

Native to eastern North America. Grows to 3–4 ft. tall and 2–2 1/2 ft. wide. Long-stalked, glossy green leaves stand well above surface of water; these are heart-shaped, to 10 in. long and 6 in. wide. Blooms from late spring to fall, bearing short spikes of blue flowers at stem ends. P. c. albiflora has white blooms; pink-flowered forms are also available. Pink- and white-flowered forms are available. Often grown as a companion to water lilies (Nymphaea); plant in pots of rich soil placed in 1 ft. of water. Gives an informal garden pool the look of a wild pond. To use in natural ponds, set plants at shoreline—underwater, directly in the soil. Goes dormant in winter.
