About
Plectranthus verticillatus (syn. Plectranthus nummularius), Swedish ivy, Swedish begonia or whorled plectranthus is a plant in the family Lamiaceae (Labiatae), genus Plectranthus native to southern Africa. Despite its common name, it is not close to the ivy family of the genus Hedera nor is it native to Sweden.
Where it grows
Plectranthus verticillatus is native to southern Africa where it occurs in the Cape Provinces, KwaZulu-Natal, Eswatini, the Northern Provinces and southern Mozambique. It is found naturalized in El Salvador, Honduras, the Leeward Islands, the Venezuela Antilles, the Windward Islands, Venezuela, Puerto Rico, Hawaii as well as south-east Queensland and coastal areas of New South Wales in Australia.
Uses
Plectranthus verticillatus is a robust plant doing well in indirect sunlight, mostly cultivated as hanging houseplant. In frost-free areas, it is also found as groundcover in gardens or sprouting down walls. It can tolerate milder frosts if it is grown under a canopy of trees and shrubs. Since it is a tender perennial, it is hardy to USDA zones 10-11. In cooler climates, it is grown as an indoor houseplant or as an annual.
