Rovaeanthus strigosus (Panama Rose) Tender upright evergreen subshrub that in cultivation is typically 3 to 4 feet tall by 2 to 3 feet wide but in the wild can be more than twice as large. It has dark green glossy leaves and primarily in summer appear the faintly fragrant flowers that have a long deep rose colored tube with flaring petals and a yellow throat - in our coastal climate there often are flowers on this plant year round. Plant in part sun to light shade in a well-drained rich soil with regular irrigation. It is only hardy and evergreen in frost free gardens, tolerating on short duration temperatures just below freezing, but possibly root hardy with mulch to around 20° F. It was described as "one of the most beautiful of all summer flowering plants for the American flower garden" by Editor Thomas Meehan in the October 1879 Gardener's Monthly and Horticulturalist: Devoted to Horticulture, Arboriculture and Rural Affairs. Panama Rose comes from the mountains of Guatemala, El Salvador and possibly south into Panama. The plant is part of what is often called the Rodeletia complex that includes Rogiera and Bouvardia and was named for Johan Rova, the Swedish botanist who studied Rondeletia and its allies. The specific epithet means refers to the strigose, or rigid hairs that are in the throat of the flower.
