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!

We pay great care and attention to our Hellebore Washfield Mixed seed production. Trained staff painstakingly pollinate each flower by hand twice to produce the best possible quality seed. All of our seed is harvested at the peak of freshness in May and June and is then immediately packed and shipped straight out to our customers. Hellebore seed germinates at its best when sown within a month of harvest so we recommend that you sow your seeds as soon as you receive them. Height: 45-60cm (18-24in).
