Pelargonium sidoides (Kalwerbossie Geranium) - This silver-gray foliaged perennial from South Africa forms tight 12 inch mounds of slightly-fragrant heart-shaped velvety leaves. The small clusters of dark burgundy flowers held high above the foliage are produced year-round in coastal California with a peak in late spring and summer. Plant in full sun in well-drained soils and irrigate regularly to occasionally spring through summer - is surprisingly water thrifty considering its origins in a summer rainfall area. It is hardy and evergreen to 25 F and can take colder temperatures but will be dormant - keep drier in winter if possible. This is an excellent container plant and has done exceptionally well in our garden plantings. Pelargonium sidoides comes from summer rainfall grasslands in the eastern Cape, Free State and Gauteng in the Republic of South Africa and the independent county of Lesotho. The name for the genus comes from Johannes Burman (1707-1780, a Dutch physician and botanist whom Linnaeus worked for in his youth. Burman first used the name to describe some South African Geraniums in 1738. The name was derived from the Greek word 'pelargós' (pe?a????) meaning "stork" because the seed head looks like that of a stork's beak. The specific epithet comes from this plant's foliage having a resemblance to that of Sida rhombifolia, a European plant in the malva family (Malvaceae) whose name was taken from an ancient Greek word for "water lily".  This description is based on our research and observations of this plant as it grows in our nursery and our own landscape plantings and in other gardens that we visit. We also incorporate comments we receive from others and appreciate receiving feedback of any kind from those who have additional information about this plant, particularly if they disagree with what we have written or if they have additional cultural tips that would aid others in growing Pelargonium sidoides
