About Hardy Gardenia Azalea

The Hardy Gardenia Azalea is a prolific spring-blooming rhododendron. Although lacking the fragrance of gardenias, this variety captures the elegance reminiscent of the southern favorite. In late April to early May, beautiful pure white double form blooms will cover this shrub.


In spring, evergreen foliage emerges as a light green before maturing to an emerald hue.


The Hardy Gardenia Azalea is a dwarf variety and matures to 2-3′ H x 2-3′ W. Therefore, it naturally won’t engulf your landscape. Rather, it tends to grow in a compact dense mound, that is a perfect solution for small areas in the landscape.


Try it in a container, low-hedge, mass planting, border, or mixed bed.


Plant it with evergreen contrasting color and texture plants for maximum effect, such as the Bronze Beauty Cleyera or Everillo Carex


Hardy Gardenia Azalea Care

Hardy from USDA Zones 7-9.


Plant in Partial Sun for best results.  Filtered Sun for much of the day or 2-3 hours of direct sun a day is sufficient. Too much sun will stress the plant, while too little sun will result in decreased foliage and bloom potential.


This rhododendron has only medium water requirements once established. For the first growing season, provide supplementary water 2-3 times a week in average weather conditions.


The Hardy Gardenia Azalea prefers acidic to neutral soil for best results. In addition, ensure that the soil drains well in order to avoid root rot.


Fertilize in early spring with a balanced acidic plant fertilizer. This will help ensure future growth and blooms, as well as promote the overall well-being of your plant.


Trim after the bloom cycle has ended. The Hardy Gardenia Azalea, like other yearly blooming rhododendrons, begins compiling the next years blooms after the end of the current years cycle. Trimming too late will decrease the amount of potential blooms for the next year.


Hardy Gardenia Azalea Spacing Recommendations

To create a seamless hedge we recommend planting 1-2′ Appart and to create individual shrubs plant at least 3-4′ apart
