Summer bulbs by flower colour

All our Summer bulbs classified by flower colour, to enhance your borders and containers all summer long, even into autumn. Discover a wide range of dahlias and lilies in all colours, crocosmias in red and orange tones, blue, white or pink agapanthus, gladioli with their infinitely varied palette, and even ornamental alliums in pink, white, mauve and purple. Also find a great selection of tuberous begonias to flower your terrace and exceptional flowering bulbs like the vibrant red Lycoris radiata or the 'Black Magic' Agapanthus with its unusual black flowers.
Plant your bulbs in spring, after the frosts, in well-drained soil, in sun or partial shade depending on the species; water regularly.
Tips: bury them at a depth equal to 2–3 times the bulb's height; mulch to retain moisture; use a potash-rich fertiliser at the start of the flowering period.
