Streptocarpus grandis ssp grandis has, as the name indicates, a massive single, monocarpic leaf (500 x 350 mm). Despite its foliar size it has relatively small flowers in abundance, and these are pale violet to white, relatively small, tube shaped flower with a long narrow corolla tube (25-45 mm) and a darker violet throat with white wedges, sometimes with yellow lines.
It grows on rocks in moss and earth embankments, always in forests patches in deep shade, in central and northern KwaZulu Natal Province of South Africa. Its impressive leaf requires inventive ways to support it if cultivated.
