This fast growing Gesneriad produces butter yellow blooms and is easy to grow. It does great in terrariums and seems tolerant of a wide variety of conditions so long as temperatures are moderate (60-80) and humidity is high. The leaves are rather thin, and have a large swath of silver down the center, with silver leaf venation.
This Episcia is native to French Guiana and does wonderfully in terrarium conditions. It will grow partially up a wood surface or over substrate. The leaves are under 4″ when full grown, and flowers are fringed white with purple in the center.
