Family: Geraniaceae
Common Name: Stork's Bill
Comprising around 60 species of annuals, perennials and subshrubs native to Europe, including the Mediterranean, temperate Asia and Australia, and South America, these plants are useful additions to borders and rock gardens. They have small flowers and attractive foliage. The seed is ejected from the pod in a quite remarkable spiralling action, reversing when it reaches the ground. They are generally easy-care plants, and valued for their long flowÂering period.
Species
E. manescavii, zone 6, a perennial from the Pyrenees, grows to 40 cm (16 in), with large, rosy purple flowers.
E. reichardii, zone 7, a perennial from Europe, has white flowers, veined in pink, and grows to 7 cm (3 in). There are some forms with pink flowers and these are well worth buying if available.
