Plant in full coastal sun to light shade and irrigate occasionally to very little. Hardy to 20 °F. A useful plant as a groundcover in the dry or succulent garden or in a container or hanging basket.

This plant comes from sandy soil along rocky outcrops and in dry woodlands near the Bashee River in the Eastern Cape of South Africa and north into Namibia. This plant has long been known as Plectranthus cylindraceus but fairly recently it was determined that the plant George Bentham first named the Indian species Plectranthus montanus in 1830 and then the African species Plectranthus cylindraceus in 1848 so when these two species were determined to be conspecific, the earlier name, Plectranthus montanus, took priority. To add to the confusion this plant has also been commonly sold as Plectranthus amboinicus (the name we got it as) but while similar, there are differences with Plectranthus amboinicus, also known as Mexican Mint (though it is from South Africa), having leaves with more of a hastate base and 7 to 11 matching pairs of teeth on the leaf tip and flowers in distinct verticillasters laxly arranged and connate stamens while Plectranthus montanus has leaves with a cuneate base and 3 to 5 pairs of teeth and flowers with stamens free that are densely arranged on the spike. Other common names include Vick's Plant and Mentholatum Plant. We grew thus plant from 2014 until 2021 and we also grew Plectranthus amboinicus. 

The information about Plectranthus montanus displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant.
