A joyful blend of a range of vibrant colours that produces an intensely sweet fragrance. Sweet Pea 'Heirloom Mixed' is a mixture of smaller flowered heirloom (Grandiflora) types, bringing bright colour and delightful scent to the garden.

In autumn, sow 3 seeds per 7.5cm (3") pot at a depth of 1cm (1/2") in free-draining, seed sowing compost.
