Eichhornia crassipes (Aquatic) (Water Hyacinth) - The petioles on this aquatic plant are swollen which allow it to float on the water. The lengths of the petiole can vary from 6 inches to 2 feet, as they get longer the swollen portion becomes elongated. The leaves have distinct parallel veins that run the entire 3 to 4 inch length. Clusters of beautiful orchid-like lilac flowers rise from the center of the leaves in the spring to fall. If planted in an outdoor pond it may die back in the winter. Does not flourish floating about aimlessly. Needs a permanent spot to prosper. This plant is a major weed in central California waterways and while useful in the pond to remove nutrients from the water it also robs waterways or oxygen and blocks light from reaching all other plants.
This information about Eichhornia crassipes displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
