Aphelandra arborea (Red Aphelandra)

Native to Venezuela, this evergreen shrub can reach about 10 feet tall. Its bright red to orange-red tubular flowers grow in four rows along upright spikes. It has been introduced to Cuba, Trinidad and Tobago, the Mariana Islands, and parts of South Asia. The older name Aphelandra tetragona is still widely used in horticulture. Photographed in Cartago, Colombia.
