Pelargonium radens, the rasp-leaf pelargonium [1] is a species of Pelargonium . It is in the subgenus Pelargonium along with Pelargonium crispum and Pelargonium tomentosum .
Pelargonium radens is an evergreen perennial plant, growing to up to 1.5 m (4 ft 11 in) high. It has deeply cut triangular scented gray-green leaves and in the summer bears clusters of small pink-purple flowers, followed by small curly-tailed brownish seeds. It is originally from the southern and eastern Cape, South Africa, where it grows in ravines or gorges near streams or among shrubs on mountainsides. [2]
Pelargonium comes from the Greek πελαργός pelargos, which means stork. Another name for pelargoniums is stork's-bills due to the shape of their fruit. Radens refers to the coarse, rasp leaves.
There are a few cultivars and hybrids of Pelargonium radens. These include:
Traditionally the edible leaves were used as a flavoring in jellies and in herbal teas. An essential oil extracted from the leaves and flowers is used commercially as a food flavoring and additive (geranium oil, rose geranium oil). This essential oil is classified as Generally Recognized as Safe by the US FDA when small quantities are added to foods.
Pelargonium radens is used as a house plant. It is also cultivated as an ornamental in, e.g., North America, in USDA hardiness zones 10–11. Propagation is by seeds and stem cuttings.
