Delphinium seeds — towering spires of true blue

Delphiniums are the aristocrats of the summer border — tall, stately spires packed with florets in pure blue, violet, white and pink that lift any planting to new heights. These classic perennials sit proudly within our flower seed range. New to flowers? Our flower growing guide gets you started.

Sow at the right moment for the strongest spires — the calendar shows when.

The backbone of the classic border

Few plants give such vertical drama, making delphiniums a centrepiece among our perennial flowers, while their nectar-rich spires draw bees high into the border — a stately addition to our pollinator flowers.

Growing delphinium from seed

Sow fresh seed under cover in spring; it germinates best in cool conditions, so keep it out of heat. Prick out, grow on, and plant into rich, well-drained soil in a sheltered, sunny spot. Stake the spires early against wind, and cut back after flowering for a possible second flush.

Planning a classic border? Here's where to look next.

Popular flower categories: Perennial Flowers · Blue Flowers · Cut Flowers · Pollinator Flowers · All Flower Seeds

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

When should I sow delphinium seeds?

Yes, they are perennials — see more in our perennial flowers. Do delphiniums need staking?
Yes, stake the tall spires early to protect them from wind, and cut back after flowering for a possible second flush. Where do orders ship from?
