Plectranthus argentifolius (Somalian Spur Flower) – A small low growing compact subshrub to about 1 foot tall spreading to 2-3 feet wide with stems that can drape over a wall or raised planter. It has semi-succulent blue-green leaves whose margins are entire or very finely toothed and in spring has showy pale-blue boat-shaped flowers on spaced stem circling clusters, called verticillasters, that cover the plant in profusion.
Plant in full sun to a brightly lit shade in a well-drained soil and irrigate occasionally to very little.
The name for the genus comes from the Greek words ‘plektron’ meaning a “spur” and ‘anthos’ meaning “flower” in reference to the spur that is found at the base of the corolla tube of the type species Plectranthus fruticosus. The specific epithet comes from the Latin words ‘argentum’ meaning “silver” and? ‘folium’ meaning “leaf” in reference to the silvery gray leaves.
