There are a number of different forms of Erodium reichardii that are suitable for light shade. They need good drainage and should generally not be planted outside in Zones 8 and below. They grow on north facing slopes in the Balearic Islands in the Mediterranean. You might think of putting them between stepping stones, in small shallow containers, as an accompaniment to bonsai specimens or in the shade sections of the rock garden.
Erodiium reichardii 'Charm' This is the regular Erodiium reichardii. The cultivar name 'Charm' has been added by someone, but it is the same plant that has been available all along. It has pale pink flowers with darker pink veins.
A scandent shrub with gray hairy pinnate leaves and flowers that have red upper petals slightly streaked with white, pure white lower petals and an almost black central blotch. 'Splendide' is best grown in a greenhouse or conservatory, but can be grown outside if protected from rain and temperatures below 40 degrees F. Prune carefully and water sparingly. It is a glorious sight when in full flower. 24" wide x 12" high.
