Azaleas -- woody shrubs known for their brightly colored spring blossoms -- come in many shapes and sizes. Most horticulturists divide azaleas into two main categories: evergreen and deciduous. Of those two categories, there are thousands of named varieties, according to the Azalea Society of America. The size of a mature azalea varies slightly based on the kind planted.
Average Height
The majority of azalea varieties grow into mature, large shrubs. The average height is typically around 4 to 8 feet, according to the Arbor Day Foundation. However, some azaleas remain closer to ground covers, reaching a mature height of about 12 inches.
Average Spread
On average, the spread of a mature azalea shrub is proportionate to its height. The tall shrub varieties reach a spread between 4 and 6 feet.
Determining Size
When purchasing azaleas from a catalog or nursery, the listed height and spread is typically the 10-year height, according to the Azalea Society of America. This is the height the azalea will reach at its mature growth.
