We have been stunned by the performance of this little-known Chinese African violet relative. The 1' long, glossy, dark green leaves of Hemiboea subcapitata are borne on opposite sides of a 1' tall, fleshy green stem. The plant spreads rapidly via rhizomes growing just below the soil surface, forming a 5' wide patch in just 2 years. Although the incredibly bold foliage is enough reason to grow it, the clumps are topped in late September with clusters of up to 25, 2" tubular white flowers, spotted purple inside. Although we have only grown this in Zone 7b, we are already hearing reports of hardiness in Zone 6...amazing!
