Conophytum truncatum ssp. truncatum var. wiggettiae grows naturally in the vicinity of De Rust, Dysselsdorp and also Calitzdorp.
In the De Rust and Dysselsdorp areas the plants prefer hills made of enon comglomerate, often with a reddish colour.
The plants themselves have a reddish tint and multiple papillae on the surface. Seedlings grown in shade often lack the reddish colour until exposed to more sunlight.
The plants however avoid full day sun by growing mostly on the southern or south eastern slope of a hill.
