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.
