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.

Building a cutting patch? Here's where to look next.

Frequently Asked Questions

When do I sow sweet peas?
In autumn or early spring; soaking the hard seed first speeds germination.

Do they need support?
Yes — they climb by tendrils to two metres or more, so give them a frame from the start.

How do I get more flowers?
Pick constantly — the more you cut, the more the plant blooms.

Are sweet pea seeds edible?
No — they are ornamental only and should not be eaten.

Which are the most fragrant?
The heritage grandiflora types are prized above all for their scent.
