The growth habit of Erica versicolor may be sprawling or erect. This is a robust shrub of 2 m tall in fynbos growing on sandstone mountain slopes from Clanwilliam to Knysna, particularly the Cederberg and the Langeberg.
The leaves are arranged in whorls of four, densely or spaced on the grey, woody stems, depending on the resources during the growth season at the time. The leaves are straight and narrow, spreading or pointing upwards along the stems. Leaf colour is green, even dark green, to yellowish green as on this specimen in the Stellenbosch University Botanical Garden.
The shiny red flower tubes are barely curved, sometimes straight with a just discernible unevenness in girth. The yellow or whitish corolla tip may have a slight green tinge on its shallowly scalloped margin. Versicolor means having a variety of colours. In Afrikaans the species is known as tweekleurige heide (bicoloured heath). Flowers may be found on E. versicolor plants at any time during the year (Manning, 2009).
