Botanical Name

Plant Common Name

Evergreen Azalea, Gable Azalea, Herbert Azalea

General Description

The Gable Hybrids are a large group of evergreen and semi-evergreen azaleas developed by Joseph Gable of Stewartstown, Pennsylvania. They feature compact rounded to spreading growth with small, shiny, elliptic leaves. 'Herbert' -- one of the hardiest of the Gables -- is a reliable spring bloomer with vivid, reddish-purple, double flowers with frilled edges and a darker throat.

Some shade is required for this azalea, especially in the hot afternoon and organic-rich, moist, acid soils are necessary. The Herbert Gable azalea works well in foundation plantings and mixed borders.
