Alaska Azalea (Rhododendron indica ‘Alaska’)

Alaska Azalea

Each of the pristine, snow-white flowers shine like fresh snow throughout the hottest of growing zones! The Alaska Azalea (Azalea indica ‘Alaska’) is accented by chartreuse, the yellow-green blotch on the throat. This perfectly chic color combination ensures that these pretty cultivars will coordinate beautifully with many other flowering plants.

Alaska Azaleas start producing showy trusses of blooms in the late midseason. Each hose-in-hose flower measures two inches across and can range from single to semi-double forms. You’ll appreciate the cool, polished tones each spring; along with refined evergreen foliage through a year-long season. Even the rounded growth habit is incredibly versatile for use in partial shade.

The pollinators and hummingbirds adore these dreamy white blooms! Alaska was the winning Evergreen Azalea of the Year for the Southwest Region. It displays more sun tolerance than others and resistance to Phytophthora root rot. Very heat and humidity tolerant, these Azaleas thrive in USDA growing zones 9-11!

Tips For Care

Select a planting site with well-drained soil and don’t plant Azaleas too deeply. They perform with no more than six hours of direct sunlight daily, please provide afternoon shade for the best results. Azaleas require slightly acidic soil with a lower pH, so create a planting mound in alkaline soils. Use a three-inch layer of mulch or pine straw over the roots to keep them cool and moist. Provide water on a regular basis during dry times when you don’t receive rainfall. Keep the surrounding areas weeded, as Azaleas have shallow roots that resent competition. Prune to shape them right after the blooms are finished in spring. Feed them with a high-quality fertilizer designed for ericaceous flowering plants.
