Pontederia cordata L.
Pickerelweed, Pickerel rush
Pontederiaceae (Pickerelweed Family)
Synonym(s): Pontederia cordata var. angustifolia, Pontederia cordata var. lanceolata, Pontederia cordata var. lancifolia, Pontederia lanceolata
USDA Symbol: poco14
The large pickerelweed plant produces 1 spike of small flowers. The plant is often 3 feet tall, with long, heart-shaped leaves. The flower stem rises above the leaves except 1 leaf that grows behind the flowers. The deep blue flowers are on a spike about 6 inches long and bloom in succession from the bottom up, prolonging the flowering period for several days.
This emergent aquatic, with its leaves and flowers above water and portions of the stem under water, is found typically in shallow, quiet water. The seeds can be eaten like nuts and the young leaf-stalks cooked as greens. Deer also feed on these plants. The common name suggests that this plant, as well as the fish known as pickerel, occupy the same habitat.
