Blue flower seeds — the garden's most coveted colour

True blue is the rarest and most sought-after colour in the flower garden, and this collection gathers the best blue-flowering varieties from across our flower seed range — from sky-blue cornflowers to deep delphinium spires. New to flowers? Our flower growing guide covers the basics.

Sow at the right time for the longest display — the calendar shows when.

Blue flowers to grow

For classic blues, sow cornflowers and the misty blooms of nigella (love-in-a-mist); for height and drama, the tall spires of delphinium; and for a soft haze, dainty forget-me-nots. Many true-blue flowers are also bee favourites, since bees see blue especially well.

Designing with blue

Blue is a cool, calming colour that recedes into a border and makes a garden feel larger. Pair it with yellow or orange for a vivid contrast, or with white and silver foliage for a serene, classic scheme. Blue flowers are lovely in the vase too, cooling down a bright bouquet.
