Sweet Pea (Tall) Horizon Mixed Flower Seeds

For a beautifully diverse selection of colours, this set of mixed flower seeds contains a range of selfs, bicolours, marbles, flakes, and picotees.

These mixed sweet pea Horizon seeds are easy to grow and grow similarly to many other varieties of sweet pea. They can be sown in autumn and overwintered or sown indoors between late winter and early spring, then hardened off and planted out once they are seedlings.

Prior to planting, add garden compost or well-rotted manure to the soil to improve growth, ideally four weeks before. When young, pinch out their tips to encourage bushy, vigorous growth. They will need a support to grow up as they are climbing plants. Water well and feed them every couple of weeks if grown in infertile or light soil.

Sweet pea Horizon mixed seeds started indoors will bloom between May and October, whilst seeds sown outdoors will bloom between June and October.
