Evergreen shrub native to Central America with exotic bright orange flowers. The calyx is much larger than the corolla, so its flowers are ornamental even when they are still in bud. It has a climbing habit, so it can be used both as a bush and on a trellis.
Juanulloa accepts light frosts and can be tried outdoors in warmer Mediterranean climates.
