Landscape Attributes
Korean Rhododendron is a multi-stemmed deciduous shrub with an upright spreading habit of growth. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

Korean Rhododendron is recommended for the following landscape applications;
- Accent
- Mass Planting
- General Garden Use
Planting & Growing
Korean Rhododendron will grow to be about 5 feet tall at maturity, with a spread of 5 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. 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 species is not originally from North America.
