Height: 3 feet

Spread: 3 feet

Sunlight:  full sun  partial shade 

Hardiness Zone: 5a

Description:

Stunning pure white blooms with no markings cover this attractive open airy shrub in mid spring; ideal when massed in borders, foundation plantings, or low screening; absolutely must have well-drained, highly acidic and organic soil

Ornamental Features:

Helen Curtis Azalea is covered in stunning clusters of lightly-scented white trumpet-shaped flowers at the ends of the branches in mid spring before the leaves. It has green foliage. The glossy narrow leaves remain green through the winter. The fruit is not ornamentally significant.

Landscape Attributes:

Helen Curtis Azalea is an open multi-stemmed evergreen shrub with an upright spreading habit of growth. 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.

Helen Curtis Azalea is recommended for the following landscape applications;

  • General Garden Use
  • Mass Planting
  • Container Planting

Plant Characteristics:

Helen Curtis Azalea will grow to be about 3 feet tall at maturity, with a spread of 3 feet. It has a low canopy. 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 zones.

This particular variety is an interspecific hybrid.
