This species is endemic to the Western Cape province of South Africa.

Hermannia lavandulifolia is remarkably drought-tolerant. This characteristic makes it an excellent choice for water-conscious gardeners, as it requires less frequent watering compared to many other plants.

This plant is part of the fynbos and is frequently visited by bees and butterflies.  A healthy example of this plant can be found in the Aquifer gardens in Steenbok.

Threats

Hermannia lavandulifolia has lost nearly 80% of its habitat to crop cultivation in the past, and this loss continues. It is also threatened by habitat loss to coastal development between Stilbaai and Plettenberg Bay. Subpopulations on the southern Cape coast are also threatened by competition from dense infestations of alien invasive plants.

Population

It is still common in spite of extensive historical habitat loss, but continues to decline. It has lost 8% of its habitat between 1990 and 2014, and based on the observed rate of loss, a population reduction of 31% over three generations (60 years) is inferred.
