Biennials live for 2 years, whereas perennials live for longer. As a general rule, biennial and perennial seeds should be sown in spring, but some can be sown in autumn as well. Many varieties will self-seed after flowering, giving you even more plants!

Geranium wallichianum 'Buxton's Blue'

Geranium wallichianum 'Buxton's Variety', Hardy Geranium, Cranesbill

This is definitely the star of the perennial geranium family producing flowers virtually non-stop from mid summer to early autumn. The flowers themselves are a delight, a gorgeous clear opal, or Nemophila blue with large white centres, against which the dark stamens and dark veining of the petals contrast beautifully. The plant forms an attractive clump with attractive wedge shaped, silky, deeply toothed leaves, making this a very garden worthy plant even when not in flower. It also comes quite true from seed.
