Autumn Angel Azalea

Rhododendron x hybrida 'Robleg'

The Story

Plant Bio

Encore Azaleas are a group of hybrid rhododendrons known for their ability to bloom in spring, summer, and fall. They are generally more sun-tolerant than traditional azaleas.

'Robleg', sold as Encore Autumn Angel, is an evergreen azalea with single white flowers and green, non-variegated foliage. It blooms in spring and repeats in summer and fall, reaching about 36 inches tall and 36 inches wide.

Uses & Benefits:

Its manageable size makes it ideal for small gardens, foundation plantings, and decorative containers. It can be used in mass plantings for a dramatic effect or as a low, informal hedge.

The repeated blooming cycles offer a prolonged nectar source for pollinators like bees, butterflies, and hummingbirds, supporting them from spring through fall.
