Where it grows wild

Records run along the southern coast of the Western Cape, from the Cape Peninsula east to beyond Mossel Bay, mostly in open sandy or gravelly patches among low fynbos and coastal scrub. Cleretum species are mostly short-lived annuals of open ground; details are inferred from the genus.

Few records carry an elevation; most are low coastal sites below about 300 m.
