This has started growing at the edge of one of our ponds. I would like to know if it is invasive, or otherwise difficult to manage, or if it would be a good plant to divide and start in other areas. As far as size, you can see it in comparison to Alligator weed, some large Pennywort leaves, and some Duckweed.
Thanks!
Ken,
this is one of the bur-heads, also called creeping water-plantain, Echinodorus cordifolius, native to a large part of North America. I do not consider it to be invasive, but some might. It is in the same family as the Arrowhead, Alismataceae. It is often found in the aquarium trade and is quite popular.
It is certainly not as invasive as the non-native alligator weed also in this image!
