Read about Cyanotis in the Standard Cyclopedia of Horticulture 

Cyanotis (Greek, referring to the blue petals). Commelinaceae. Probably 40 creeping, ascending or weak branching often woolly or hairy herbs, much like Tradescantia; they are native in warm countries about the globe. Lvs. sheathing, small or medium in size, various: fls. in scirpioid cymes or variously disposed, mostly blue or rose-colored; sepals 3, lanceolate-carinate, nearly equal, usually combined at base into a short tube: petals 3, also nearly equal, often connate in a tube, the limb spreading and suborbicular; stamens 6, all perfect, nearly equal; ovary sessile, 3-cclled and each cell 2-ovuled. Easy of cult.; prop, by cuttings. There are few species in cult.; perennial; grown in greenhouses or warm- houses. C. hirsuta, Fisch. & Mey., from Abyssinia, villous or glabrous, has erect st., globose tubers, linear soft-hairy lvs., and rose-colored perianth and blue-bearded filaments. B.M. 7785. C. barbata, Don, of E. India, has elongated branching nearly glabrous st., narrow-oblong or nearly linear lvs., and blue spatulate-oblong petals free to the base: ovary hirsute at apex and the style bearded. C. kewensis, Clarke, of E. Indies, is procumbent, reddish-hairy, leafy, the branches fleshy: lvs. a half or more longer than broad, sessile and amplexicaul: petals rose-purple, ovate, free; filaments bearded. B.M. 6150 (as Erythrotis Beddomei). C. nodiflora, Kunth, of S. Afr., is cobwebby or woolly but becoming glabrous, the fibrous roots terminating in tubercles: lvs. narrowly lance-linear: petals blue, lightly connate. B.M. 5471. L.H.B.
