Azaleas And Rhododendrons: How To Tell The Difference

Azaleas and rhododendrons are two popular flowering shrubs that are often confused with each other. In fact, they are actually members of the same genus, Rhododendron. However, there are some key differences between the two plants that can help you tell them apart.

Flower Shape and Size

One of the most obvious differences between azaleas and rhododendrons is the shape of their flowers. Azalea flowers are typically funnel-shaped, while rhododendron flowers are more bell-shaped. Azalea flowers are also generally smaller than rhododendron flowers.

Stamen Number

Another way to tell azaleas and rhododendrons apart is by counting the number of stamens in their flowers. Azalea flowers have five stamens, while rhododendron flowers have ten or more stamens.

Leaf Shape and Texture

The leaves of azaleas and rhododendrons are also slightly different. Azalea leaves are typically thinner and more pointed than rhododendron leaves. They may also be covered in fine hairs. Rhododendron leaves are thicker and more leathery, and they are usually hairless.

Deciduous vs. Evergreen

Most azaleas are deciduous, meaning they lose their leaves in the fall. However, there are also some evergreen azaleas. Rhododendrons, on the other hand, are typically evergreen, although some species may lose their leaves in cold climates.

Growth Habit

Azaleas and rhododendrons can vary in size, but rhododendrons are generally larger shrubs than azaleas. Rhododendrons can grow up to 20 feet tall, while azaleas are typically only 3-6 feet tall.

Growing Conditions

Both azaleas and rhododendrons prefer acidic soil and partial shade. They are also both susceptible to root rot, so it is important to plant them in well-drained soil.

So, how can you tell the difference between an azalea and a rhododendron?
