Panama rose (Arachnothryx leucophylla)

Description

Clusters of rose-red, sweetly fragrant flowers bloom from December to June on this easy-to-grow container plant. The flowers have a delightful scent that intensifies at night, and they are butterfly and hummingbird attractors when grown in the outdoor garden. Panama Rose prefers full sun and well-drained soil. Rondeletia is a genus of flowering plants in the family Rubiaceae. It is endemic to the neotropics. There are around 160 species. Rondeletia odorata is widely grown as an ornamental. Several other species are also known in cultivation. Rondeletia was named in 1753 by Linnaeus in his book, Species Plantarum. This genus name commemorates the French physician Guillaume Rondelet (1507-1566). The type species for Rondeletia is Rondeletia americana. It is little known and rarely collected. The circumscription of Rondeletia has varied greatly from one author to another. Rogiera, Arachnothryx, and a few others have been included in Rondeletia by some authors, but molecular phylogenetic studies have shown that they are closer to Guettarda than to Rondeletia, and they are now recognized as separate genera. Even with these segregates removed, Rondeletia remains polyphyletic and will be substantially revised after further phylogenetic study.
