Sweet Pea Seed – Duo Salmon

Lathyrus odoratus ‘Duo Salmon’

Two perky pinks for the price of one.

£4.00 Min. 15 seeds per pack


Why settle for one pink when you can have two? This striking bi-colour sweet pea has produced an abundance of flowers since we began trialling it at Easton Walled Gardens a couple of years ago, where we like to grow it with our semi-grandifloras.

The flowers on this heritage variety might be slightly smaller than their contemporary counterparts – but they make up for it with their bushy plants, bountiful stems and spirit-lifting scent – not to mention their mood-boosting pink tones. Look out for the hints of peach this variety produces: a rare colour for sweet peas.

Your Duo Salmon Sweet Pea Seeds will need scarifying…

All seeds need water to germinate. But some have thicker, tough coats that stop water from penetrating and slow down their growth. In gardening, we use a process called scarification to soften a tough seed coating, allowing moisture in and encouraging the seed to germinate.

To scarify your seeds:

  • Use sandpaper to wear down the coating.
  • You can sand your seeds individually or together. To do them together in one go, pop them and the sandpaper in a jar, close the lid and shake vigorously.

Most sweet pea seeds will germinate without scarification, but if yours aren’t showing any signs of growth, then it’s worth checking to see if they need a helping hand. To do this:

  • Carefully excavate the seeds from their pots.
  • If you find a squidgy seed with white mould, then it has succumbed to dampening-off disease and unfortunately can’t be saved.
  • If the seeds look the same as when you planted them, then scarify and replant them. They should then germinate as normal.

Capturing the Gardens’ magic in a illustrated seed tin…

Sweet pea seeds grown and harvested with this much care deserve to have a thoughtful container to keep them stable and dry. So we made a fully-recyclable seed tin – decorated with an original Easton Collection design. Created by Ursula Cholmeley and blooming with sweet peas, the design reflects the colours found in the Arts and Crafts motifs of the Edwardian era when sweet peas were as adored at Easton as they are today.
