It's not just the lovely scent that distinguishes the sweet pea. The long flowering period makes this flower a must-have in the garden. Grow them against a support of some kind, such as a fence or pergola. Sweet peas benefit from harvesting. The more often you pick them, the more they flower. So you can enjoy bouquets well into late summer. Explore our hand-picked selection of sweet pea favourites and let yourself be seduced by a variety of flowers in the most delightful colours.
