A compact evergreen azalea that is part of the Encore series, known for its ability to bloom multiple times a year. It has small, glossy green leaves that may take on a purplish cast in winter.

'Autumn Amethyst' is prized for its vibrant, single, 2-inch purple flowers that appear in spring, summer, and fall. Its foliage turns a deep purple in winter, providing year-round color.

Uses & Benefits:

Care Guide

Do

Maintain acidic soil conditions (pH 4.5-6.0).
Water consistently, especially in summer heat, to support reblooming.
Mulch well to protect the shallow root system.
Fertilize with an acid-forming fertilizer after the spring bloom.

Don't

Do not plant too deep; azaleas are shallow-rooted.
Do not let the soil dry out completely between waterings.
Avoid using lime or fresh manure around the plant.
Do not prune late in the season, as this will remove fall flower buds.
