Welcome to Roger Parsons Sweet Peas

We hold the National Collection of Sweet Peas (Lathyrus odoratus) and other Lathyrus species. This includes over 1300 varieties of Sweetpeas and all Lathyrus in cultivation. We believe this website advertises the largest selection of Sweet Pea varieties in the World but we cannot include them all. If you are looking for a particular Sweet Pea and cannot find it here, please ask because we should have seed available in our seedbank.


Roger Parsons Sweet Peas was founded in 2005 and has quickly built a reputation for excellent germination and the high purity of our varieties. We produce seed here in Sussex where emphasis is placed on conserving the quality of varieties and the storage of our seed so that it remains harvest fresh. In addition to our emphasis on conservation of cultivars, Roger uses the enormous genepool we hold to produce new Sweet Peas with innovative form and colours, and to improve existing colours and types.


Our nursery is unsuitable for visitors and seed is sold via our ONLINE SHOP, E-MAIL, MAIL or PHONE ORDER ONLY. For details of how to order,
click how to order.


We offer an interesting selection of gardening gifts for those seeking something different, including personalised gift packs and our Essential Guide to the cultivation and history of the genus. For further details, please click on our gifts page.
