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!

Himalayan Poppy, Tibetan Poppy, Meconopsis betonicifolia

  • Rare white Himalayan poppy
Rarely seen, this stunning white form of the Himalayan blue poppy is a real eye-catcher in late spring and early summer.

This captivating short-lived perennial is 99% true to type; very occasionally the odd blue flower may appear. Height: 90cm (35"). Spread: 50cm (20").
