What is the difference between an azalea and a rhododendron?

Azaleas are a member of the rhododendron genus. An azalea are generally more petite and set apart by its smaller leaves. Azaleas don’t tend to be evergreen, while rhododendrons remain intensely green during winter. However, rhododendrons flower slightly less abundantly than azaleas.

Hortinno’s Evergreen garden azaleas retain their leaves well in winter.
