Plectranthus nummularius[2]), Swedish ivy, Swedish begonia or whorled plectranthus[3]) is a plant in the family Lamiaceae (Labiatae), genus Plectranthus. DescriptionThe plant has aromatic glossy, green, round leaves, which show a deep purple color in the center sometimes and tend to trail. This deep purple can also be found on the plant stems and on the underside of leaves. The upright racemes appear white, pale violet or pale pink and can sprout sporadically throughout the year.[4][5] The name "Swedish ivy" is deceptive: the plant is not thigmotropic (meaning it does not cling to walls with the roots when it grows), is not native to Sweden, and is not closely related to the genus of ivy (Hedera). Some variegated, slivery plants called Swedish Ivy grown in pots and hanging baskets are Plectranthus oertendahlii from coastal river gorges of KwaZulu-Natal.[6] DistributionPlectranthus verticillatus is native to southern Africa where it occurs in the Cape Provinces, KwaZulu-Natal, Swaziland, the Northern Provinces and southern Mozambique.[7] 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.[3][7][8]Use as ornamental plantPlectranthus 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.[9][10]It likes to stay moist and it also responds well to pruning. It can easily be rooted with cuttings and its vulnerability is low; but a weak plant can be infested with spider mites.[11] References1. ^{{cite web|title=Plectranthus nummularius Briq.|work=African flowering plants database|publisher=Conservatoire et Jardin Botaniques Ville de Geneve|url=http://www.ville-ge.ch/musinfo/bd/cjb/africa/details.php?langue=an&id=116882|accessdate=2009-02-03}} 2. ^cf. theplantlist.org: Plectranthus verticillatus (L.f.)
