Introduction
This twining, evergreen sprawling vine has 4 inch long, coarsely toothed, dark green leaves and terminal clusters of orange-red, one-inch, daisy-like flowers with golden centers. Although it appears throughout the year, peak periods of bloom are spring and summer. The quick growth of Mexican flame vine is ideal to add interest to palm trunks, to soften fences, or to veil a trellis. Occasional heading helps some foliage and flowers at the bottom of a fence or other structure supporting Mexican flame vine. Left unpruned, foliage and flowers accumulate at the top.

Use and Management
Easily grown in full sun or partial shade, Mexican flame vine thrives in any soil with little care. Although knocked down by frost, it will quickly recover in USDA hardiness zones 8b and 9. Growth rate is so rapid, it can be used as an annual vine, planting yearly in areas subjected to freezing winter temperatures.
The cultivar 'Sao Paulo' has deeper orange, almost brick red flowers.
Propagation is by seed or stem cuttings. The green, fleshy stems will root at the nodes when in contact with soil.
