The US is so screwed up.
I recognized the name of this plant because a client has it as the main plant in his aquarium at work.
You can buy Egeria Densa online and have it delivered anywhere in the country for about $20.
Then it escapes when little Ricky dumps the aquarium with the dead fish in the local stream for a funeral, and the plant propagates like mad.

Lakes, ponds, and swamps throughout the deep south are being coked by another former aquarium plant that has gotten into local waters, Duckweed. It even showed up 2 years ago in a small decorative pond in my backyard.
