Uncovering the Past of the Pig Lily Plant

The perennial pea plant, Lathyrus latifolius, originated in Europe and Northwest Africa. It was introduced to American gardens before 1720, already popular in European landscapes. Thomas Jefferson sowed it at Monticello in 1807, cementing its place in early American horticulture.
Over time, the perennial pea’s vigorous growth and showy flowers made it a favorite for roadsides and gardens. Its ability to thrive in various conditions led to its naturalization across much of the United States. Today, this resilient plant continues to captivate gardeners with its colorful blooms and hardy nature.
