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).

Pansy 'Jolly Joker' F2 Hybrid

Viola x wittrockiana

Jolly Joker, awarded the AAS Medal 1990 and the 1990 Fleuroselect Gold Medal, is probably the most spectacular pansy of its class. The intense orange of its lower petals, contrasts sharply with the deep purple of the upper petals. The effect is both unusual and intriguing. A very versatile and hardy variety which can be sown early for summer flowers or in summer for flowering in autumn and spring and even; in mild winters, through the winter. Height: 15-23cm (6-9in).

Culinary note: Some parts of these flowers are edible. The crystallised petals are great decorations for cakes and cookies, or they can be added straight to green salads for an injection of colour. For more details about edible flowers click here.
