Sweet pea seeds — the most fragrant climber you can grow
Sweet peas are the great romantic flower of the summer garden — ruffled, intensely scented blooms on long stems, perfect for filling the house with perfume. The species is gathered under Lathyrus odoratus within our flower seed range, and they're a favourite of any cutting garden. New to flowers? Our flower growing guide covers the basics.
Sweet peas are sown in autumn or early spring — the calendar shows the timing.
Scent, colour and long stems
From heritage grandifloras prized for fragrance to modern Spencer types with large, frilled flowers, sweet peas climb by tendrils to two metres or more, so they belong among our climbing flowers. Their nectar-rich blooms are good for pollinators too.
Growing sweet peas from seed
Soak the hard seed to speed germination, then sow into deep pots or direct, and give them a sturdy support to climb from the start. Rich soil, plenty of water and — above all — constant picking keep them flowering: the more you cut, the more they bloom. Note the seeds are ornamental only, not for eating.
