This is a rhizomatous species Geranium (ht 30 cm) from southern Europe that is one of the easiest to grow in Sydney. It forms a good, dense groundcover mat, up to 30-45 cm across, of aromatic, rounded leaves and simple, pretty flowers in spring. The basic species has magenta flowers but there are cultivars in colours of white, purplish and various shades of pink. It will grow well in shade (even quite dry shade) or sun and doesn't need any special treatment to do well. It appreciates occasional watering and fertilising in late winter. To propagate, detach pieces of the rhizomes.
One favourite cultivar is 'Ingwersen's Variety' (pictured above), with soft pale pink flowers. Others include 'Album' (white) and 'Bevan's Variety' (crimson-purple).
