This beautifully marked Marcgravia is from Ecuador, and is easy to grow on horizontal or vertical surfaces.  It will grow tightly to a background.  The reddish purple stem and white leaf venation makes it a stunning plant for the vivarium. In a terrarium the leaves stay under an inch.

The plants available are well rooted and growing in 2″ pots.  They will be shipped potted.  The last photo is representative of the size plant available.
