Bloomsz Bog Plant Pontederia Cordata Pontederia Cordata, also known as Blue Pickerel, are native to North America and add interest to the margins of ponds and water gardens. An ornamental plant, the clumps of leaves at the waters edge provide shelter for all types of fish, not just pickerel, giving the plant one of its common names. The green leaves are glossy, narrow, and arrowhead-shaped. Flower stems rise above the leaves except for one leaf that provides a background for the tubular soft blue flowers with yellow markings. Flowers begin to appear in June, and flowering often continues into October. Pre-planted in a weighted net bag to protect the tuber from being eaten by fish, simply drop the plant in the desired place in the pond. There is no need to purchase anything else to enjoy this plant. Pontederia Cordata can be grown in rain barrels and containers as well as ponds and water gardens. Winter hardy  You dont have to remove the plants from the pond or water garden during the winter. Grows and blends in well with other plants along the margins of ponds and water gardens.
