About Girard's Roberta Azalea

The Girard’s Roberta Azalea is a prolific spring-blooming Girard hybrid rhododendron. This selection produces deep pink with a darker rose spotted blotch in mid-spring. Evergreen foliage emerges as light green in spring before maturing to a deep green hue in summer.


The Roberta Azalea matures to 2-4′ H x 3-5′ W, and makes a great hedge, mass planting, border, or mixed bed.


Girard’s Roberta Azalea Care

Hardy from USDA Zones 6-9


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 Roberta 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 Roberta 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.

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