Astrophytum capricorne

Astrophytum capricorne, the goat's horn cactus, is a species of flowering plant in the cactus family Cactaceae, that is native to the Coahuila regions of Northern Mexico.[2] Growing to 25 centimetres (9.8 in) tall by 10 centimetres (3.9 in) wide in a ball or oval shape, it is grey-green in colour with 7 to 9 prominent ribs, very long twisted spines and yellow flowers with a red centre in summer.[3]

The common name of goat's horn cactus corresponds to the species identifier capricorne (capri meaning “goat” and corne meaning “horn”) [4] referring to the curved spines that are said to resemble a goat's horns.[2]

This species is designated as of "least concern"[5] by the IUCN as it is widely distributed in the Chihuahuan desert.

Cultivation[edit]

This species is grown, typically from seed, as an ornamental plant as it produces large, attractive yellow flowers with red central regions.[2] Some cultivars bear white flecking on the plant body while others lack this feature.[6] Though tolerant of cold temperatures, it must be grown in a warm, sheltered spot which does not freeze in winter. The soil should be poor, alkaline and very sharply drained. Alternatively it can be grown under glass in a pot with cactus compost. In cultivation in the UK, Astrophytum capricorne has gained the Royal Horticultural Society’s Award of Garden Merit.[3]
