Medinilla is a tropical broadleaf evergreen plant. If you’ve traveled through Southeast Asia, you may have marveled at this tropical beauty growing on tree branches, dangling its vivid 18-inch flower panicles down like clusters of otherworldly grapes. Flower gardeners who live in USDA growing zones 10 and 11 can grow Medinilla as a tender perennial outdoors, but others must grow this exotic flower as a houseplant or patio tropical.
