Botanical Description
Dionysia curviflora
Forming rather flat green or grey-green, dense cushions, composed of numerous crammed, tiny, leaf-rosettes; no farina. Stems columnar, covered in closely overlapping dead leaf remains. Leaves forming tiny rosettes, oblong to oblong-spathulate, 2-3mm long, hairy along the flat untoothed margin and in the top half above. Flowers solitary and sessile; corolla pink to lilac with a white eye, surrounding a yellowish zone, the tube 11-12mm long, the limb 6mm diameter with heart-shaped lobes clearly notched at the apex. Central Iran, Yazd Province, Schir Kuh and Kuh-e Barfkhane, on shaded or partially shaded basalt or volcanic cliffs, 2500-4000m. The longest cultivated species and one of the easiest and most reliable species to grow; more recently introduced forms are more floriferous than the old clones of the 1930s. Relatively easily raised from cuttings and seed is sometimes produced in cultivation. Long-lived plants may reach 20cm diameter in as many years. Clones of wild origin in cultivation include JCA2800, SLIZE268, T4Z014, JLMS02-06, DZ I 01-02. There are numerous f1 and f2 hybrids in cultivation.
