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 pratense 'Purple Haze'

Hardy Geranium, Meadow Cranesbill

One of the hardy Geranium discoveries of the century! 'Purple Haze' is a stunning plant, producing amazing foliage with a unique bronze-purple hue, a shade rarely seen in hardy Geranium foliage. The leaves are deepest in shade during spring, gradually changing to an attractive deep green with strong purple edging. Even more exciting is the striking contrast of the blooms, perfectly themed in shades of gorgeous violet-mauve. Height: 60-75cm (24-30in).
