Description:

This stunning, compact evergreen shrub is bathed in clusters of beautiful white blooms every spring and has loads of interest for the rest of the year; an excellent choice to mass in groupings or as a focal point of the garden

Ornamental Features

Cascade Azalea is smothered in stunning clusters of lightly-scented white trumpet-shaped flowers with a chartreuse blotch at the ends of the branches in mid spring before the leaves. It has dark green foliage throughout the season. The narrow leaves do not develop any appreciable fall colour. The fruit is not ornamentally significant.

Landscape Attributes

Cascade Azalea is an open multi-stemmed deciduous 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.

Cascade Azalea is recommended for the following landscape applications;

  • Accent
  • Mass Planting
  • General Garden Use

Planting & Growing

Cascade Azalea will grow to be about 5 feet tall at maturity, with a spread of 6 feet. It tends to be a little leggy, with a typical clearance of 1 foot from the ground, and is suitable for planting under power lines. 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. 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 leaves 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 particular variety is an interspecific hybrid.
