Clusters of elegant white blooms cover this azalea in mid spring, contrasting the dark green foliage; this dense dwarf variety stands out as a compact shrub that is great along borders; needs highly acidic and organic soil that is well drained
White Kyushu Azalea is bathed in stunning clusters of lightly-scented white trumpet-shaped flowers at the ends of the branches in mid spring before the leaves. It has dark green evergreen foliage. The small glossy oval leaves remain dark green throughout the winter.
White Kyushu Azalea is a dense multi-stemmed evergreen shrub with a more or less rounded form. Its relatively coarse texture can be used to stand it apart from other landscape plants with finer foliage.
This is a relatively low maintenance shrub, and should only be pruned after flowering to avoid removing any of the current season's flowers. It has no significant negative characteristics.
White Kyushu Azalea is recommended for the following landscape applications;
Planting & Growing
White Kyushu Azalea will grow to be about 3 feet tall at maturity, with a spread of 3 feet. It tends to be a little leggy, with a typical clearance of 1 foot from the ground. It grows at a slow rate, and under ideal conditions can be expected to live for 40 years or more.
This shrub does best in full sun to partial shade. You may want to keep it away from hot, dry locations that receive direct afternoon sun or which get reflected sunlight, such as against the south side of a white wall. It requires an evenly moist well-drained soil for optimal growth, but will die in standing water. It is very fussy about its soil conditions and must have rich, acidic soils to ensure success, and is subject to chlorosis (yellowing) of the foliage in alkaline soils. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America.
