Pseudogynoxys chenopodioides is a twining, herbaceous vine with smooth stems and alternate arrowhead-shaped evergreen leaves sometimes reaching a height of 5 m (17 ft).
It has orange to red ray flowers and orange disc flowers, and ribbed fruits with persistent bristles that appear from spring to fall.[4][5]
The Mexican flamevine is prized as an ornamental because of its showy flowers. It is widely grown in gardens in parts of the United States. It requires full sun, well-drained soil, and either a trellis or a shrub to climb on.[6] In colder areas, frost will kill the shoots, but the roots can survive the winter in most of the contiguous United States.[7][8] It can be grown as an annual plant due to its rapid growth rate. If not grown as a vine, it will grow in a sprawling shrub-like form.[9]
It is cultivated in Florida and has been reported as persisting after cultivation there, growing on disturbed sites.[4]
