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!

Pitcher Plant

Plants will be mature enough to catch insects after 2 - 3 years. Height: 30cm (12"). Spread: 20cm (8").
