This gesneriad is hardy and quite sturdy once established, and offers broader leaves for larger Dendrobatid species.  It benefits from pruning every so often, so as not to crowd out slower growing plants, but it also looks quite nice grown in a very large colony.  It has reached about 8″ in my conditions but could probably get slightly larger. The flowers are creamy white, and plants bloom often. It grows in South America.

The plants available are rooted and growing in 2″ pots.
