Blue Pickerelweed, Pickerelweed
The pretty and prolific pickerelweed is a very common aquatic perennial that withstands fresh or brackish water. It is an emergent, or marginal, aquatic plant and prefers to be immersed in water a foot deep or less and naturally grows in wetlands and lake shallows in eastern North America from Canada to Florida.
Its large leaves are oval, linear or triangular. They are fully deciduous in northern areas and evergreen down south. The flowers are small and borne on upright spikes held above the foliage. They are lavender-blue and appear all summer.
Pickerelweed is a very easy to grow if given full sun and rooted in mucky soil covered with a shallow layer of water. It tends to spread rapidly by rhizomes, or creeping underground stems, so plant it where it can naturalize. If you wish to control its spread, submerse it in pots.
