Known by the scientific name of Lathyrus odoratus, this species is native to Southern Italy. It is a climbing plant that reaches a maximum of 2 m in height. The tendrils from the leaves twist around other plants and use their support to climb. With cultivation, the generally purple flowers sport white, pastels, and rich magentas. Despite the dainty look, the plant is quite hardy. L. Odoratus is the species that means ‘fragranced or perfumed,’ so it’s a perfumed legume.

Sweet Pea flower cultivation
The Sweet Pea Flower has been cultivated since the 17th century. These flowers are usually grown for the colored flowers and the intense scent and are produced in private gardens or exhibitions. These flowers are cultivated in cold weather and available in other seasons as young plants. The flowers tend to appear in midsummer. Sweet Pea flowers survive in open woods, forest margins, pastures, fields, slopes, and roadsides.
Distribution
This plant was highly restricted to its native region of Southern Italy. However, now it has been widely introduced as an ornamental plant everywhere. It is considered invasive in New Zealand and the Dominican Republic. Historically, in the late 1600s, these flowers were sent to England, where the breeding and selection of the sweet pea flower began. In the latter part of the 1800s, more than a hundred cultivars were breeding.
Ecology
The sweet pea flowers have hermaphroditic flowers pollinated by bees. In the northern hemisphere, the species flowers from July to September and bears fruits from August to October. In China, flowers and fruits are delivered from July to September. The plant grows in heavy soil in moist areas. Therefore, well-drained soils are preferred, with a pH of 7 to 7.8.
Toxicity
The seeds may pose to be toxic if ingested in larger quantities. In addition, if these plants are grown too close to each other, they may cause a fungal infection. This infection takes out all the nutrients and hinders their growth.
Propagation
Sweet Pea Flower propagates by following these steps:
- Choose the seedlings.
- Cut the stem at a length of 5 inches just from the flower’s leaves.
- Place the cuttings in the water, and place them on a windowsill that receives indirect sunlight.
- Wait to have the roots develop, which usually develop in two weeks.
- After seeing the seeds, put their roots in a potting mix.
- After six weeks, one will see new growth.

Risk factors
Sweet pea flowers are invasive in non-native areas. The plant is highly adaptive to different environments. It is a fast-growing plant that may pose a problem to loss of life for other native plants. Because of its rapid growth and demand as an ornamental plant, it can be a monopolizing plant for resources.
Uses
This plant is highly cultivated as an ornamental plant. However, due to the high demand for sweet pea flowers, there is a risk of the native population declining. In addition, it is poisonous to mammals and can attract a host of pests.
