Haworthia ernstii

A recently described Haworthia (M. Hayashi, 2018) from South Africa's Cape Provinces. There are no wild records and little published beyond the description, so these conditions follow what suits Haworthia of the dry South African interior: bright but shaded light, warm growing seasons and a cool, dry winter.

Where it grows wild

Like most Haworthia it presumably grows partly buried among stones or in the shade of shrubs, which protects it from full sun. No species-specific habitat notes were found.

Unknown; the reference point is at about 1,040 m.
