R. blackii Distinct circular leaves, nearly sessile (without a leaf stem) leaves tightly attached to the plant stem. Red tubular flowers 5-9 to a truss. |

R. bryophyllum Noted for the dense brown scales covering most of the leaves which are arranged in tight pseudowhorls, making this an outstanding foliage plant. The small pink flowers just add to its charm. A relatively upright and narrow growth habit makes it easy to tuck it in a corner. Needs very good drainage. |
