Beautiful large purple blooms with dark red spots adorn this majestic shrub in mid to late spring; dark green foliage has burgundy overtones to add interest; absolutely must have well-drained, highly acidic and organic soil
Purple Passion Rhododendron is covered in stunning clusters of lightly-scented purple trumpet-shaped flowers with dark red spots at the ends of the branches in mid spring. It has burgundy-spotted dark green foliage which emerges green in spring. The glossy narrow leaves turn an outstanding coppery-bronze in the fall. The fruit is not ornamentally significant.
Purple Passion 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.
Purple Passion Rhododendron is recommended for the following landscape applications;
Planting & Growing
Purple Passion Rhododendron will grow to be about 6 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.
