Pelargonium acetosum

This is a marvellous, somewhat sprawling species with attractive, blue-green leaves that have more than a passing resemblance to those of Gingko, albeit not as lobed. Here on the far south west coast of England, it can be trained against a low wall, allowed to tumble down a dry sunny bank or grown in a hanging container. Given a sunny spot it carries its palest coral, spidery flowers almost throughout the year. If you are into 'in your face', 'over the top' plants with large gaudy flowers this is not for you, but it has a gentle charm and the sheer numbers of flowers can make it quite spectacular in summer. It can withstand very light, short-lived frosts, but only if grown in sharply drained soils. Definitely a 9b. plant.

This Pelargonium is a sub shrub with brittle stems and dainty flowers. It likes dry, well drained conditions and in a sunny spot will flower for a very long time. It is ideal for a large container, which can be moved to shelter in adverse conditions. This is a South African native and is not frost hardy
