Azaleas have woody shrubs with a variety of growth habits. Some types are compact and low-growing, while others can reach up to 1.8-2.4 meters tall. The leaves are dark green, oval-shaped, and sometimes glossy, with a soft texture. They turn yellow or red in the fall in many species. The flowers come in clusters and are tubular, with 5 petals. The blooms often have a fragrant scent and can be single or double depending on the variety.
