Description:

Beautiful wavy-edged red-purple blooms on conical trusses cover this attention getting shrub in mid spring; an accent shrub that will definitely make an impact; absolutely must have well-drained, highly acidic and organic soil

Ornamental Features

Midnight Ruby Rhododendron is covered in stunning clusters of lightly-scented ruby-red trumpet-shaped flowers with purple overtones and a dark red blotch at the ends of the branches in mid spring. It has dark green foliage with hints of coppery-bronze. The narrow leaves remain dark green throughout the winter. The fruit is not ornamentally significant.

Landscape Attributes

Midnight Ruby Rhododendron 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.

Midnight Ruby Rhododendron is recommended for the following landscape applications;

  • Accent
  • Mass Planting
  • General Garden Use

Planting & Growing

Midnight Ruby Rhododendron 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. 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.
