Invasive Plant
Leafy elodea
Egeria densa*

A perennial freshwater aquatic plant that grown completely submerged. The stems grow to 2 metres or more and are floating with roots at the lower nodes and narrow, undivided leaves in whorls of 3 to 8 at each node. White flowers are attached to long thread-like stems and float on surface of water but do not form seed in Australia.



Leafy elodea spreads by stem fragments that are carried downstream by water, and it it can choke waterways at some seasons, excluding other aquatic life and stopping the movement of boats.
