Streptocarpus caulescens

A stemmed, shrubby African violet relative from the Eastern Arc mountains of Kenya and Tanzania, especially the Taita Hills and the Usambaras, at roughly 550 to 1,900 m. It grows in shaded forest on rocks and banks, so it wants mild temperatures, moderate shade and humid air rather than heat or sun.
