Opuntia pycnantha

A low, densely spined prickly pear of the Pacific coastal plains of Baja California Sur, recorded mostly below 100 m on the sandy Magdalena Plain. It needs full sun, a hot dry rhythm with late-summer storms, and protection from wet cold; it is a straightforward greenhouse plant if kept dry most of the year.

Where it grows wild

Open desert scrub on sandy and gravelly coastal plains, where cool Pacific fog moderates the heat. This is inferred from the recorded sites and the genus; species-specific habitat notes were not checked.

Recorded from about 4 to 575 m, median 45 m; nearly all records are on the low coastal plain.
