Azalea Autumn Monarch

Autumn Monarch Encore Azalea

Azalea ‘Autumn Monarch’ is a bold Encore® evergreen azalea prized for its rich royal purple flowers and reliable reblooming habit. It flowers heavily in spring, then continues to bloom summer through fall, delivering long-lasting, saturated color well beyond the traditional azalea season.

This cultivar develops a dense, upright to rounded habit with dark green, glossy evergreen foliage, giving it strong year-round structure. ‘Autumn Monarch’ is one of the larger-growing Encore azaleas, making it an excellent choice for focal plantings and informal screening.
