This is a ‘staple’ Marcgravia in the terrarium, due to its fast growth habit and ease of keeping.  The leaves on this species stay between .5-1 inch in the immature state (rare to get mature foliage in a terrarium).  It is bright green with slightly yellow new growth.

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.
