Azaleas and Rhododendrons, with their magnificent flowers, are some of the best-loved sights of spring. Producing a blaze of color from early spring through the summer and even into the fall, Azaleas and Rhododendrons are popular ornamental shrubs for gardens of all sizes. Evergreen or deciduous, they come in all shapes and sizes, from small, ground-hugging shrubs to large, tree-like specimens. Their flowers range from the tiny and delicate blossoms of floriferous dwarf shrubs to the huge clusters or ‘trusses’ of tall growing hybrids and species. Some are fragrant, and others feature wonderful foliage adding glorious fall color to the landscape. All are fascinating.

Azaleas and Rhododendrons are members of the genus Rhododendron, one of the largest genera in the plant world, which includes over 900 species and over 20,000 named hybrids of Rhododendrons and Azaleas. Attractive landscape plants in cool and moist climates, many varieties have been struggling in New England as a result of floods, blizzards, bare-ground winters, northeasters, heat waves, cold snaps, hurricanes, and even the odd tornado.

The following is a list of Azaleas and Rhododendrons recognized as proven performers in New England. Most have received the Rhododendron of the Year Award from the American Rhododendron Society. To be selected for such an award, a plant must have excellent foliage and flowers, have an attractive plant habit, be pest and disease-resistant, and be cold-hardy for the region.

Remember that the ability to grow Azaleas and Rhododendrons successfully depends also on the site selection and soil preparation.

  • Their soil should be acidic, organic, moist, fertile, and well-drained.
  • Choose a site with dappled shade in sheltered conditions. Avoid deep shade beneath other trees. Most Rhododendrons will tolerate a more open site if sheltered from cold, dry winds. Dwarf alpine species will tolerate full sun provided the soil is kept evenly moist.
  • Many Azaleas and Rhododendrons are fully cold hardy, however, a few of them have frost-resistant flowers. Any flowers blooming before the last spring frost are susceptible to damage. Since the frost damage is generally caused when the early morning sun strikes the plants’ frozen tissues, you should site your Azalea or Rhododendron where both leaves and flowers are protected from the early morning sun, and where they will adapt slowly to the increasing temperatures of the day. Since frost flows downward, avoid planting them in low-lying spots known to be frost pockets.
  • When placing plants, always choose locations that mitigate extreme temperature changes, especially in spring and fall, and provide protection from drying summer or winter winds. Azaleas and Rhododendrons may be harmed in winter by frozen grounds and drying winds or bright sun which will cause severe foliage desiccation. Protect their shallow roots with a mulch of oak leaves or pine needles and their foliage with woven material such as burlap screens. This will help in preventing bark-split (when the sap running in the stem is frozen and burst the bark).
