Pelargonium peltatum is a species of pelargonium known by the common names ivy-leaf geranium and cascading geranium. It is native to southern Africa, particularly South Africa. It is commonly grown as an ornamental plant. This is a subshrub which can reach two meters in height, its branches prostrate, spreading, trailing, or climbing. The thin, somewhat succulent leaves are peltate, their petioles attached at the middle of the ivy-shaped leaf blades. The inflorescence is an umbel of 2 to 9 pink flowers, with 5 dark-streaked or marked petals each up to 2 centimeters long. The smaller leaves of the plant are edible, tasting sour and astringent.
Pelargonium peltatum is included in the Tasmanian Fire Service's list of low flammability plants, indicating that it is suitable for growing within a building protection zone.
