Erica discolor is a dense shrub growing to heights from 1 m to 5 m. E. discolor forms part of the Evanthe section of the Syringodea subgenus, characterised by terminal, long-tubed flowers.
The species is found in the Western Cape from Stellenbosch along the southern mountain ranges to the Swartberge and the western part of Eastern Cape.
The habitat is coastal and montane fynbos. The plant is not considered threatened in habitat early in the twenty first century (Baker and Oliver, 1967; Manning, 2007; iSpot; www.redlist.sanbi.org).
