Quick Overview:

Pontederia cordata, commonly called pickerel weed, is a vigorous, deciduous, emergent marginal aquatic perennial that typically grows 2-4’ tall. It is native to quiet waters at stream and pond margins from Nova Scotia south to Florida and Texas.  Plants flower freely from June to October. Flowers give way to starchy seeds with distinctive toothed ridges. Flower spikes droop after bloom, releasing the distinctive seeds into the water. Seeds are edible off the plant or can be dried and added to granola cereals. Very young leaves can be used as salad greens. Dragonflies and damselflies commonly lay their eggs on plant stems near the water surface. Fish (albeit more than just pickerel) may seek shelter in clumps of these plants, hence the common name of pickerel weed.


Winter hardy to USDA Zones 3-10. Needs full sun for best flowering. Set plant roots in spring into mud at the margins of a pond or in containers (rich organic loams) in a water garden under 3-5” of water. Outside of containers, rhizomes can spread rapidly to form colonies under optimum growing conditions. If spread is a concern, grow plants in containers.
