Chonemorpha penangensis
 
Common Names Frangipani Vine, Penang Frangipani, Climbing Frangipani
 
Zones 10B–11 (outdoors); Zone 9B with protection or container overwintering
 
Chonemorpha penangensis is a rare, large-flowered woody climber native to Southeast Asia, closely related to Chonemorpha fragrans but distinguished by its intensely fragrant blooms and more vigorous growth. This tropical vine produces creamy white flowers with golden centers, emitting a perfume stronger than most plumerias. Its lush, dark green foliage and dramatic summer flowering make it a showpiece for trellises, pergolas, and tropical conservatories2.
