About Red Formosa Azalea

The Red Formosa Azalea is a spring-blooming southern indica hybrid rhododendron. This Azalea produces bright red single-form blooms. In spring, lush green evergreen foliage emerges as a light green before maturing to a deep green hue.

The Red Formosa Azalea matures to 6-8′ H x 4-6′ W. Use this Azalea in hedges, small screens, borders, foundations, mixed beds, or accent plantings.

Plant it with contrasting color and texture plants for maximum effect, such as the Soft Caress Mahonia or Nandinas

Red Formosa Azalea Care

Hardy from USDA Zones 7-10.

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 Red Formosa Azalea prefers acidic to neutral soil for best results. In addition, ensure that the soil drains well 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 Red Formosa Azalea, like other yearly blooming rhododendrons, begins compiling the next year’s blooms after the end of the current year’s cycle. Trimming too late will decrease the number of potential blooms for the next year.

Red Formosa Azalea Spacing 

To create a seamless hedge, we recommend planting 4′ apart. To create space for the individual plants to show their form, plant them at least 6′ apart.
