Hardiest Azaleas and Rhododendrons
Deciduous Azaleas, Evergreen Azaleas, Lepidote Rhododendrons, Elepidote Rhododendrons
Gracing woodland gardens and shrub borders with their magnificent flowers, Azaleas and Rhododendrons are popular ornamental shrubs for gardens of all sizes. Evergreen or deciduous, these members of the genus Rhododendron 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, others feature a wonderful foliage adding glorious fall color to the landscape. All are fascinating but some varieties can tolerate severe winter conditions while others cannot.
The following list of Azaleas and Rhododendrons are exceptionally cold hardy and can withstand temperatures as low as -26ºF (-32ºC). They have all been recognized as proven performers and have received the Rhododendron of the Year Award of the American Rhododendron Society. Among them are some Iron-clads hybrids, which are regarded as the hardiest Rhododendrons and can tolerate open sites in sun (provided their roots remain moist).
