Lathyrus odoratus. Grow some history! These most unusual Italian heirloom sweet peas are bi-coloured violet and deep maroon. Matucana sweet pea seeds are thought to be one of the first sweet peas to be introduced to Britain in 1700 by a Sicilian Monk, Franciscus Cupani. Matucana sweet peas have an intoxicating scent and smaller flowers than many modern varieties that bloom over a long period in summer. Provide some support for this rampant climber and it will reward you with stunning beauty and fragrance. And be sure to pick off spent flowers before they form seed pods. This will keep the plants blooming longer. Matucana is one of our staff favourites.
