Erica discolor is a dense shrub growing to heights from 1 m to 2 m. E. discolor forms part of the Evanthe section of the Syringodea subgenus, characterised by terminal, long-tubed flowers. Discolor means variegated, referring to the two colours present on the corolla tubes.
The species is found in the Western Cape from Stellenbosch and Betty's Bay along the southern mountain ranges to the Swartberge and the western part of Eastern Cape to around Humansdorp.
The habitat is coastal and montane fynbos. The habitat population is deemed of least concern early in the twenty first century (Manning and Helme, 2024; Euston-Brown and Kruger, 2023; Manning, 2007; Baker and Oliver, 1967; iNaturalist; iSpot; http://redlist.sanbi.org).
