Though its common name is Panama rose (Rondeletia leucophylla), this plant is actually a native of Chiapas, Mexico. This large, bushy, 5-foot-tall shrub produces massed clusters of bright pink, star-shaped, tightly packed, tubular blooms virtually all year when grown as a container plant or in the ground in a frost-free conservatory. Cultivated in the southern United States, the flowers' nectar attracts both hummingbirds and butterflies, but interestingly, the flowers don't become fragrant until after the sun goes down, suggesting that it also may be pollinated by moths. This feature is an added bonus for those who sit in the garden in the evening, where they can enjoy the Panama rose's sweet fragrance. Grow this plant in full sun with moderate moisture.
