Planting & Growing

Oosterwijk Winterberry will grow to be about 6 feet tall at maturity, with a spread of 8 feet. It has a low canopy 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 variety requires a different selection of the same species growing nearby in order to set fruit.

This shrub does best in full sun to partial shade. It prefers to grow in moist to wet soil, and will even tolerate some 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. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This is a selection of a native North American species.
