Hyla cinerea (Green Tree Frog) hanging out with Pontederia cordata (Pickerel Weed) in Historic Blakely State Park. 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 Alabama. In the wild, it is frequently seen growing in dense colonies. Glossy, narrow, arrowhead-shaped green leaves (to 10” long) have rounded cordate bases and rise well above the water surface. Tiny, tubular soft blue flowers are densely packed into erect, 3-6” long spikes atop flower stalks typically rising 1-2’ above the water surface. Plants flower freely from late May 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. Dragonflies and damselflies commonly lay their eggs on plant stems near the water surface.
