Pseudogynoxys chenopodioides, commonly known as Mexican flamevine, is a twining, herbaceous vine native to Mexico and Tropical Americathrives in tropical and subtropical forests, often climbing on other vegetation to reach sunlight. It is evergreen in areas without frost and can reach heights of up to 5 meters (17 feet). The vine is characterized by its smooth stems and alternate, arrowhead-shaped leaves. Its vibrant orange to red ray flowers and orange disc flowers bloom profusely from spring to fall, attracting pollinators such as butterflies and hummingbirds.

Mexican flamevine is celebrated for its showy flowers and is commonly used in gardens for trellises, fences, and as a cover for shrubs, providing a burst of color throughout the growing season. It is relatively easy to maintain, requiring full sun and well-drained soil. While it can tolerate a range of soil types, it flourishes in fertile, loamy soils. In regions with frost, the above-ground shoots may die back, but the roots often survive to regrow in the spring. Gardeners in colder climates can grow it as an annual or overwinter it indoors. It is important to be aware that Pseudogynoxys chenopodioides can become invasive outside its native range, so gardeners should check local regulations before planting.CC BY-SA 4.0
