Fragrant Shade-Loving Herb with Traditional Uses
Tilo (Justicia pectoralis), also known as Piri Piri and Willow Herb, is a perennial trailing or climbing herb native to Mexico, Central America, and South America. A member of the Acanthaceae family, it features lance-shaped leaves and delicate flowers in shades of white, pink, lavender, blue, and purple that appear in loose clusters at the ends of its branches. Tilo is commonly found along roadsides in its native range and is also grown as an ornamental flowering plant in the Caribbean, where it has naturalized.
Its aromatic dried foliage contains coumarin and has a long history of traditional use. Indigenous peoples have brewed the fragrant leaves into tea and tonic preparations traditionally associated with digestive issues, coughs, and colds, as well as ceremonial preparations. In the garden, Tilo makes an attractive shade-loving groundcover or small shrub, with delicate blooms that carry a light vanilla fragrance and attract hummingbirds and butterflies.
