ISI 2013-22. Haworthia ‘Three-Cornered Hat’

Most hybridizers eventually graduate beyond the F1 generation, the initial cross of two species. This is because the F1s so often express a muddied combination of characteristics of the two parents; F2s liberate us into purer realms of fantasy. Occasionally, however, F1s are quite attractive and well worth cultivating. Haworthia ‘Three-cornered Hat’ is a cross of H. koelmaniorum, perhaps with H. viscosa, made by Bob Kent’s trained hummingbird. Bob gave the plant to Steven Hammer, who in turn shared it with us; the present name, a reference to its three-ranked leaves and de Falla’s 1917 ballet, El Sombrero de Tres Picos, was already attached. In this slow-growing hybrid, leaves can stack one upon another up to six deep, and are glossy, coppery-brown, covered with concolorous tubercles. Another notable feature, though not necessarily a selling point, is the elongated inflorescence. One specimen, once extracted from the overhanging branches through which it had scrambled in our greenhouse, measured an astonishing 2.6 m long! Pride goeth before the fall. Rooted plants of HBG 110000, from tissue culture. $10.
