Pickerel Weed, or Pickerelweed, Pontederia cordata Lanceolata, is a native Maine wildflower that grows in wetlands where there is still water. The clusters of spiked flowers and arrow shaped leaves provide habitat for fish and frogs which are then eaten by raccoons, herons and egrets. For a list of protected and endangered wildflowers in Maine see http://plants.usda.gov/java/threat Wildflowers should be left undisturbed where they are found. To uproot and attempt to transplant them puts the species at risk. Wildflowers are dependent on very specific soil, water and light requirements which a home gardener can rarely reproduce. - Robin Robinson Maine
