10 (20)cm ø, native to La Palma, El Hierro and la Gomera, sharing similar habitats as Greenovia aurea, yet growing in more open locations in the lower zone of the pine-tree forest. It is very similar to Greenovia aurea, yet even larger, and hardly to distinguish from the latter if not flowering. In general its' rosettes are slightly smaller - with exeption of populations in the northwestern parts of the Caldera de Taburiente (Barranco de Izcagua), where plants may gain up to 25cm in diameter. Rosettes are usually some 10cm to 20cm ø, light yellowish green in full sun and finely white powered, if plants are grown in full sun. During their summer dormancy rosettes will close cup-like and are covered with beige-red, dry leaf sheaths. The flowers are even larger than those in Greenovia aurea. Young leaves are ciliated at their edges (magnifying glasses). Plants will never form any offsets, so that propagation is only possible either by seeds or by leaf cuttings, of which the latter is rather difficult and not recommended for beginners. Originally from La Palma, Northwestern side (Barranco de Izcagua) and southern side (Barranco de Las Angustias) of the Caldera del Taburiente (650m), respectively La Gomera in the vicinity of Roque Agando and in the Barranco de Guarimar. Greenovia diplocycla is botanically a very diverse species with several forms and possible some varieties, so that further scientific work is required on their taxonomical status. IV-VI.
