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!

Cynara cardunculus

The ripening seed heads of Cynara cardunculus are a fantastic combination of bronzes and golds. The stems are thick and sturdy, the foliage is large, serrated and silver and in its own right presents an imposing border plant for most of the year.
