Where do sweet peas live?

Sweet peas (Lathyrus odoratus) are native to the Mediterranean region, particularly in southern Italy and Sicily. They thrive in temperate climates and prefer well-drained soil with plenty of sunlight. Cultivated sweet peas can be found in gardens and flower beds across many parts of the world, as they are popular for their fragrant blooms and climbing habit. They can be grown as annuals in cooler climates or as perennials in milder regions.
