Elizabeth Blackerby, 1984. Pelargonium 'Rio Grande' x Pelargonium '?'. Flowers are double and deep velvety purple with a white stripe on the edge of some petals.
This charming geranium for light shade comes originally from the UK where it was first introduced in 1989. It has pale green and very light creamy-yellow veined and splashed leaves and mid lavender flowers with a white eye. It forms a low mound about 12 x 18" when mature. It is very useful under shrubs and trees in the garden where it produced little splashes of artificial sunshine. It is cold hardy from USDA Zone 4-5 up to Zone 9.
