Western Azalea • Rhododendron occidentale

In early spring, the Western Azalea starts producing new leaves. Alongside leaf growth, flower buds also begin to form.

Typically from late spring to early summer, it bursts into bloom. Clusters of small, fragrant flowers appear in shades of white, pink, or pink with yellow or orange markings. After flowers have been pollinated, small green fruits begin to form. These fruits are dry capsules that contain tiny seeds.

As the days grow shorter and temperatures start to cool in the fall, the leaves change color. Depending on the individual plant and environmental conditions, the leaves may turn shades of yellow, orange, or red. The mature capsules of the fruit split open and release the small seeds inside. 

Winter brings the long dormant period, where all above ground branches will lose foliage and its remaining seeds, and buds will start to prepare for the next growing season.

Choose a planting site that offers dappled sunlight to partial shade. In its native habitat, Western Azalea grows under the canopy of larger trees, so it prefers similar light conditions. Avoid full sun, especially in hot climates, as it can stress the plant.

It thrives in acidic soils with a pH of 4.5 to 6.0. Ensure the soil is well-draining to prevent water-logging, which can lead to root rot and other bacterial diseases. Select a location with consistent moisture. While Western Azalea can tolerate some dry periods, it prefers soil that remains consistently moist (but not waterlogged).

Minimal pruning is generally required for Western Azalea. Remove dead or damaged branches as needed. If shaping is necessary, do so after flower petal fall to avoid removing excess potential flower buds.
