Eichhornia crassipes (Common Water Hyacinth)

Eichhornia crassipes, commonly known as the common water hyacinth, is a type of aquatic flowering plant found in freshwater habitats throughout numerous states and territories across North America.

This species belongs to the Pontederiaceae family, a group of perennial flowering plants often located near shallow bodies of water with medium-high nutrient levels.

The common water hyacinth is native to the Amazon basin, though it has been introduced throughout many states and provinces in North America. In Texas specifically, Eichhornia crassipes can be found in aquatic habitats along much of the Gulf Coast region. Its vibrant purple blossoms often attract attention from wildflower lovers looking to add a bit of color to their landscape.

Though visually appealing, the common water hyacinth can be quite bothersome in natural habitats due to its rapid growth and ability to choke out smaller plants.

When not manually controlled, this species can quickly overtake bodies of water by forming dense mats which prevent light from passing through. This can make it difficult for native species to thrive, which is why it’s important for landowners to be mindful of where they introduce this plant.

The common water hyacinth can provide a unique element to any landscape when used responsibly. Its delicate blossoms and lush foliage are sure to draw the eye, so long as it is kept from taking over its environment.
