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.
The information presented on this page is based on research that we have conducted about this plant in our library and from reliable online sources. We also consider observations we have made of it growing in the nursery's garden and in other gardens we have visited, as well how it performs in our nursery crops out in the field. We will incorporate comments that we receive from others as well and welcome getting feedback from anyone who may have additional information, particularly if they have knowledge of cultural information that would aid others in growing Eichhornia crassipes. |
