REASON FOR INTRODUCTION
Ornament
 
INVADES
Drainage ditches, irrigation channels, dams, ponds, swamps, wetlands, lakes and slow-moving rivers or streams.
 
IMPACTS
Dense infestations exclude native plants and have multiple negative impacts on water transport, fisheries and recreation, and can increase the abundance of mosquitoes. The high tannin content also means that fish do not eat the plant. In California, control costs of this weed over a two-year period were US$ 215,000 (Anderson, 1993). Additional impacts would be similar to those of water hyacinth.
