Encephalartos relictus

A tall blue-green cycad from Eswatini, now extinct in the wild; only male plants were ever found, so it survives only through offsets in cultivation. Grow it like other lowveld Encephalartos: sun, heat and summer water, with a drier, cooler winter.

Where it grows wild

Its original wild habitat is poorly documented. The conditions here follow the one measured point in Eswatini at about 390 m and the genus in warm, summer-rainfall savanna and rocky hillsides.

No wild records with elevations; the measured point is at 394 m.
