Biennial flower seeds for next year's display

Biennials are the secret of a classic cottage garden — sown one year to flower spectacularly the next. Grow stately hollyhocks, spires of foxgloves, scented sweet Williams and cheerful wallflowers from seed for a fraction of the price of plants.

New to growing flowers? Our guide covers sowing and growing flowers from seed.

How biennials work

Sow biennials in early summer, grow them on over their first year, and they burst into bloom the following spring and summer. A little forward planning is all it takes — and many self-seed afterwards, returning year after year on their own. They are wonderful for cutting and for pollinators.

Cottage-garden favourites

For height, grow foxgloves and hollyhocks; for scent and edging, sweet Williams and wallflowers; for romance, honesty and Canterbury bells. Browse all flower seeds for more.

Planning ahead for next season? Explore the full flower range or start with statuesque foxgloves.

Popular biennial flowers

Foxglove · Hollyhock · Sweet William · Wallflower · Honesty · Canterbury Bells

At SeedsChoice, every order ships from Meppel, NL with fast EU delivery.

Frequently Asked Questions

What is a biennial flower?
A plant that grows leaves in its first year and flowers, sets seed and dies in its second — so you sow ahead for next year's display.
When do I sow biennials?
Usually early summer, so plants are well grown before winter and flower the following spring and summer.
Do biennials come back?
The original plants flower once, but many — like foxgloves and honesty — self-seed freely and return on their own.
Are they good for bees and cutting?
Yes — foxgloves, sweet Williams and wallflowers are loved by pollinators and make lovely cut flowers.
Do you ship across the EU?
Yes, orders ship from Meppel in the Netherlands with fast EU delivery, and the final shipping cost is shown at checkout.
