The Cupani sweet pea, scientifically known as Lathyrus odoratus 'Cupani', is a highly fragrant heirloom variety that holds a special place in the history of sweet peas. This variety was first introduced to England in the late 17th century by a Sicilian monk named Francis Cupani, who sent seeds to Dr. Robert Uvedale of Enfield. The Cupani sweet pea is notable for its intense fragrance and distinctive coloration.

The flowers of the Cupani sweet pea are typically bicolored, featuring a deep, rich maroon or purple standard (the upper petal) and a vivid deep blue or violet wing (the lower petals). This striking color combination makes them particularly eye-catching in the garden. The blooms are smaller than those of many modern sweet pea cultivars, reflecting their heritage status, but what they lack in size, they more than make up for in their strong, sweet fragrance, which is often described as more intense than that of other sweet pea varieties.

Cupani sweet peas are vining plants, usually reaching heights of 5 to 6 feet (about 1.5 to 1.8 meters) when provided with adequate support, such as a trellis or fence. They produce a profusion of flowers from early summer until the first frosts of autumn, under ideal conditions. These plants prefer full sun and well-drained soil, and like other sweet peas, they benefit from regular watering, especially during dry periods.

Gardeners often grow Cupani sweet peas for their historical significance, captivating fragrance, and the vibrant splash of color they add to garden beds, borders, and containers. They are also excellent for cutting gardens, as their long stems and enchanting scent make them perfect for bouquets and floral arrangements.
