High Invasion Risk - Central, North, South

Pyrostegia venusta Flame Vine

Edward F. Gilman, Ryan W. Klein, and Gail Hansen


Also known as Pyrostegia ignea, Flame Vine grows rapidly. Climbing by tendrils, this vigorous evergreen vine makes a brilliant fall and winter display of reddish orange, 3 inch long tubular flowers borne in clusters of 15 to 20. Covering everything that can offer a good support, flame vine should be planted with caution because it has been known to cover, then strangle, trees with its rampant growth. It has escaped cultivation in much of central Florida and is often seen in flower during the winter and spring, growing in trees. It can be found occasionally in the southern parts of hardiness zone 8b. Heavy or frequent pruning is needed to restrain it to trellises or arbors, but the brilliant flower display makes this extra work worth the effort. It is ideal for covering fences but will often produce most of the flowers and foliage at the top of the fence. Regularly heading back several of the stems can help develop some of the flowers and foliage on the lower and middle portions of the fence.
