Summary

Pontederia cordata, commonly known as pickerelweed, is a perennial herbaceous aquatic plant native to shallow waters of ponds, lakes, and streams in the American continents, including wetland areas and marshes. It typically grows to a height of 2-4 feet and a width of 2 feet, with a clumping habit. The plant is notable for its lance-shaped leaves and spikes of purple flowers with yellow markings, which bloom in late summer and are highly attractive to bees for pollination. The flowers are showy and make a striking display when planted en masse. After flowering, the stem bends to submerge the fruits and seeds, which require stratification to break dormancy. Pickerelweed reproduces both sexually through seeds and asexually via branching rhizomes, allowing it to form extensive colonies.

Pickerelweed is valued for its ornamental qualities and wildlife support in water gardens and naturalized pond settings. It prefers full sun to part shade and thrives in wet, fertile soils with fluctuating water levels. It is relatively low maintenance but may require management to prevent excessive spread in smaller ponds. In cultivation, it is recognized for its ecological benefits, such as providing habitat and food for aquatic wildlife. The Royal Horticultural Society has awarded it the Award of Garden Merit. However, it can be potentially invasive outside its native range, so gardeners should check local regulations before planting.CC BY-SA 4.0
