The sweet pea (Lathyrus odoratus) is a flowering plant in the genus Lathyrus in the family Fabaceae. It is native to the eastern Mediterranean region from Sicily east to the Aegean Islands and Turkey.

Description

Sweet peas are annual climbing plants, growing to a height of 1–2 meters (3 ft 3 in – 6 ft 7 in), where suitable support is available. They are known for their fragrance and are a popular choice for gardens and floral arrangements. The flowers come in a variety of colors, including white, pink, red, blue, and purple.

Cultivation

Sweet peas are typically grown from seeds. They prefer a sunny position and well-drained soil. The seeds are often soaked overnight before planting to encourage germination. Sweet peas are usually sown in the spring, although in milder climates, they can be sown in the autumn for earlier flowering.

History

The sweet pea was first described by Francisco Cupani, a Sicilian monk, in the late 17th century. The plant was later introduced to England in the 18th century, where it became a popular garden plant. The sweet pea has been extensively cultivated and hybridized, resulting in numerous cultivars with a wide range of colors and forms.

Uses

Sweet peas are primarily grown for their attractive and fragrant flowers. They are commonly used in cut flower arrangements and as ornamental plants in gardens. The flowers are also used in the production of perfumes.

Toxicity

While sweet peas are beautiful and fragrant, it is important to note that the seeds of the plant are toxic if ingested. They contain a compound called aminopropionitrile, which can cause a condition known as lathyrism if consumed in large quantities.
