Definition

Noun: 1. A specific aquatic plant: "Water orchid" is the common name for Eichhornia crassipes, a free-floating, perennial, tropical aquatic plant. It is characterized by its thick, glossy, rounded leaves that form rosettes on the water's surface, and it produces spikes of showy, lavender to blue flowers. It is notorious for its extremely rapid growth and ability to form dense mats that clog waterways.

Usage

Advanced Usage

  • The invasion of the water orchid has led to a decline in fish populations.
