    Landscape Attributes

    Hellikki Rhododendron is an open multi-stemmed evergreen 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.

    Hellikki Rhododendron is recommended for the following landscape applications;

    • Accent
    • Mass Planting
    • General Garden Use

    Planting & Growing

    Hellikki 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. 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.

    At Dutch Growers, we treat this plant as a "HOBBY PLANT". It is not officially recognized as winter-hardy in our zone 3, however, there is a strong liklihood that it will survive winter. Warranty expires on Nov. 1 season of purchase.
