Habitat and Location:
Arthrostemma ciliatum, commonly known as pinkfringe, is native to the tropical regions of the Americas between Mexico and Bolivia/Brazil. It thrives in moist, well-drained soils along forest edges, riverbanks, and disturbed areas at elevations between 500 to 1,500 meters. This species prefers warm, humid conditions and has also naturalized in Hawaii, where it grows in similar habitats.
Description:
This evergreen shrub can reach heights between 1 to 4 meters, forming an open, spreading habit. It is characterized by its striking pink to purple flowers with prominent stamens, blooming throughout the year in tropical conditions. The leaves are ovate, deeply veined, and distinctly purple beneath, adding to its ornamental appeal. Its rapid growth and self-seeding nature make it both an attractive garden plant and a potential invasive species in certain regions.
Care Instructions:
For optimal growth, Arthrostemma ciliatum should be placed in a warm environment with bright, indirect light or partial sun. It thrives in well-draining, fertile soil with a pH between 5.5 and 7.0. Water regularly to maintain consistent moisture, allowing the top layer of soil to dry slightly between waterings. High humidity (above 60%) is beneficial, and occasional misting can help replicate its natural habitat.
Maintain daytime temperatures between 22-30°C (72-86°F) and nighttime temperatures around 15-20°C (59-68°F). Protect from cold drafts and temperatures below 10°C (50°F). Prune to control its size and shape, especially in tropical and subtropical gardens where it can spread aggressively. Fertilize monthly with a balanced fertilizer during the growing season to encourage healthy growth and flowering. Propagation is best achieved through stem cuttings rooted in moist soil.

This species is a visually stunning addition to tropical gardens, but in certain regions, particularly Hawaii, it is considered an environmental weed due to its aggressive growth. Cultivation should be managed responsibly to prevent unintended spread.
