Ludwigia Arcuata that currently reside in a community tank that includes bladder snails so quarantine if you do not want hitchhikers! 

You will be getting a mix of tops cut from the plants pictured.

Ludwigia hybrid, it grows rapidly as a floating plant it can also be planted. This plant has grown free floating and developed thin roots that stretch towards the bottom of the tank, my shrimp love the floating maze it creates
