Detailed Description:
Azalea ‘Formosa Red’ is one of the most widely planted Southern Indica azaleas, known for its vibrant red-purple flowers that blanket the shrub in spring. With an upright, spreading habit and evergreen foliage, it provides both seasonal color and year-round structure. In Willis, Conroe, and The Woodlands, this azalea is typically maintained at 6–8 feet tall, though it can reach 10 feet if left unpruned. Hardy to about 10–15°F, it is better suited to our colder winters than varieties grown closer to the Gulf Coast. Tough, colorful, and dependable, ‘Formosa Red’ remains a staple for North Houston and Montgomery County landscapes.
