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!

Hellebore 'Washfield Doubles'

Helleborus x hybridus

Breathtaking, double-flowered Hellebores from the Washfield collection, bred to perfection, adding sheer delight to your borders early each year. T&M are proud to continue the breeding work started over 20 years ago by Hellebore specialist Elizabeth Strangman, and want to share her passion for these intriguing plants with you. These delightful doubles are in a wide colour range including yellows, greens, blacks, reds, apricots and much more.

We pay great care and attention to our Hellebore 'Washfield Doubles' seed production. Trained staff painstakingly pollinate each flower by hand twice to produce the best possible quality seed. All of our seed is then harvested at the peak of freshness in May and June to ensure the best possible germination. We lock in that freshness by immediately packaging the seed in hermetically sealed foil packets so you can sow and grow your hellebores at any time of year. For best results we recommend sowing the seeds as soon as you receive them and to use all seed within 4 weeks of opening the packet. Height: 45-60cm (18 - 24")
