Opuntia chiangiana

A rare, tall prickly pear (2.4–3 m) with strong spines and sour, reddish-purple fruit. It is known only from the Cuicatlán district of Oaxaca, Mexico, where it grows in hot, seasonally dry valley scrub at about 600–800 m. Grow it like other tropical Mexican Opuntia: full sun, a mineral mix, a summer-wet and winter-dry rhythm, and protection from frost.
