I cannot tell you what the name or color is---I do know it is a miniature! It got confused when I did some massive divisions---I would happily trade this for a:

tropical lily

nuphar

lobelia cardinalis

cyperus(except alternifolius---this is the umbrella palm)--there are several others--some are very spiky instead if large leaves--etc!

Frog's bit

water poppy

water snowflake

or maybe another water plant--ask me---I do have a lot already so I want to be sure I don't have it!

Let me know--
