Perennial & Biennial Seeds


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 Buxtons Blue

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 comes quite true from seed and has been given an Award of Garden Merit by the Royal Horticultural Society. Requirements: One of the easiest perennials to cultivate, happy in sun or light shade and any free draining garden soil. More info
