The Johanna Azalea is a prolific spring-blooming rhododendron. This selection produces brilliant stunning red blooms. These flowers are single-form ruffled edges. Each spring you will be anticipating a great colorful display of blooms that will last for weeks.
Evergreen foliage emerges as a light green before maturing to an emerald hue. As the temperatures begin to drop in autumn the foliage will begin to bronze then take on a red hue that will remain until spring.
The Johanna Azalea is considered a dwarf variety and matures to 3-4′ H x 4-5′ W. Therefore, it naturally won’t engulf your landscape. Rather, it tends to grow in a compact, dense spread.
Try it in a container, hedge, mass planting, border, or mixed bed. Furthermore, it responds well to shaping, so feel free to trim away.
Johnanna Azalea Care
Hardy from USDA Zones 6-8.
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 Johanna 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 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 Johanna 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 number of potential blooms for the next year.
Johnanna Azalea Spacing Recommendations
