Erica ventricosa is a species of plant in the family Ericaceae native to the Cape Floristic Region.

The scientific name of this species is derived from the Latin word ventricosus, which means swollen or inflated.

It naturally occurs on mountain slopes in the Paarl and Stellenbosch area of the Hottentots-Holland range, when the elevation is higher than 300 m above sea level.

Population groups of these plants are normally found in well-drained acid soils with a pH between 5.5 and 6.5.

[3] This form is no accident, as there are specialist flies with a long proboscis that are adapted to pollinate it.
