Common name: Pickerel weed, pickerel rush
Pontederia cordata is native to North and South American wetlands. The common name 'pickerel' may come from the fish with the same name, as the plant likes to live at the edges of lakes where the pickerel fish shelter. It is found at the edge of the pond in the Canadian Heritage Garden. The genus is named after Giullio Pontedera, and the species name refers to the rounded bases of the narrow oval leaves (cordata means heart-shaped).
