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!

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.

Culinary note: Some parts of these flowers are edible. For more details about edible flowers click here.
