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!

Strelitzia reginae 'Mandela's Gold'

Bird of Paradise, Strelitzia reginae 'Kirstenbosch Gold'
