Rhododendrons and Azaleas are some of the easiest and most rewarding flowering shrubs you’ll find. The huge clusters of bright, colorful flowers bloom heavily for weeks with virtually no effort. They are great for use along foundations, in woodlands, and along garden or lawn borders and are available in a multitude of colors. Long known as a staple of Southern gardens, they are actually hardy for all but the coldest regions of the country and make any garden a showstopper.
Did you know that all Azaleas are Rhododendrons but not all Rhododendrons are Azaleas? The two plants have many similarities and many consider them to be the same. However, there are some important distinctions between the two. Knowing those differences allows gardeners to properly care for the shrub.
Azaleas can either be deciduous or evergreen. The leaves are typically thin and smooth with fuzzy undersides. This shrub typically produces 1 to 3 flowers per stem and each bloom can host 5 to 6 stamen. Another notable difference is the smaller stems and branches when compared to Rhododendrons.
Rhododendrons are almost always evergreen with only a few exceptions. Instead of fuzz, the undersides of their leaves are dotted and scaled. The flowers appear in large clusters or trusses at the end of the stems, which are far fewer and stouter than those of azaleas. The colorful blooms of rhododendrons have many more stamen, usually 10 or more per blossom.
Producing an abundance of color from spring to summer and even into the fall both Azaleas and Rhododendrons are a popular shrub for gardens of all sizes. Now that you know the difference plant them with confidence and watch them transform your landscape!
