This silvery-green Floscopa has bright red roots! It loves water and does well in a seasonally flooded space, a high humidity terrarium, or grown hydroponically.  It might be suitable as a houseplant as well, if given ample water.  It is from Ecuador, but may occur elsewhere in South America.

Available plants are well rooted in 2″ pots.  They will be shipped potted.  The last photo is representative of the size plant you will receive.
