Senecio confusus), known commonly as Mexican flamevine,[3] orange-flowered groundsel[4] and orange glow vine,[5] is a climber in the family Asteraceae, native to Central America and the West Indies.

It is a vigorous vine with thick evergreen, deep green leaves and bright orange daisy-like flowers, which are borne in clusters, and usually bloom all year round.

Its evergreen leaves are simple, dull, alternate, arrowhead-shaped, toothed or serrated, 2-4 inches long, glabrous, somewhat fleshy, ovate to lanceolate, often unequal, membranaceous with conspicuous venation, slightly cordiform and obtuse base, and acute apex.

[8] It features moderately scented,[10][11] daisy-like, orange ray flowers (which age to a bright red or vermilion upon pollination) that are 1 inch in diameter with golden tubular corollas on terminal clusters.

[8] Polycarpic, the plant will sporadically bloom all year-round in mild winter climates, though generally peaking in spring and summer.

[4] The plant's former scientific name Senecio confusus translates to "confused old man", which refers to the pappus bristles on the achenes and the vine's rampant, irregular habit of growth, respectively.

[7] Due to its distribution ability by wind-dispersed seeds and stem fragments (which can root readily), it has become an escaped plant that is naturalized along roadsides, forest edges, moist thickets and disturbed sites.

[8] P. chenopodioides is a nonhost of Digitivalva delaireae and this moth is an ineffective biocontrol of invasive Flame Vine[19] Nematodes, mites, scales, and caterpillars can also disturb the plant.

[9] Leaves may have irregular reddish-purple patches, either due to nutrient deficiency, or infestation by Alternaria senecionis, a fungus which causes leaf lesions.
