Orchid cactus (Disocactus ackermannii)
Description
Disocactus ackermannii is an epiphytic cactus from tropical forests in the states of Veracruz and Oaxaca, Mexico. In cultivation, it has been confused with Disocactus × hybridus, a hybrid between D. phyllanthoides and D. speciosus. The stems of Disocactus ackermannii consist of a short rounded base, about 10–18 cm (4–7 in) long, followed by longer flattened leaf-like portions, 10–75 cm (4–30 in) long and 5–7 cm (2–3 in) wide with wavy edges. The plant branches from the base and arches downwards, being altogether some 1 m (3 ft) long. The scarlet flowers have greenish throats and are funnel shaped, 11–14 cm (4.3–5.5 in) long. Fertilized flowers are followed by green to brownish red fruits, 4 cm (1.6 in) long and 2–2.5 cm (0.8–1.0 in) wide. In cultivation, Disocactus ×hybridus, a hybrid between D. phyllanthoides and D. speciosus, has been confused with D. ackermannii and is often distributed under the name "Phyllocactus ackermannii".[2] Disocactus ackermannii has gained the Royal Horticultural Society’s Award of Garden Merit.
