'Nanum' is a cranberrybush viburnum selected for its very compact, very dense, low-growing ways, reaching maybe 2 to 2.5 feet tall and just slightly wider. It has small, glossy green, trilobed leaves that display a golden yellow to orange fall color. Flowering and fruit production are sporadic, okay, practically non-existent - the price of selecting its primary characteristic. Useful in smaller spaces, parking islands, or at the fridges of larger shrubs where some greenery would be nice.
Grow in well drained soil, preferably of a loamy nature, in full sun to partial shade. While adaptive to a variety of soil types, best growth occurs in fertile sandy-loam or clay-loam soils. Tolerant of alkaline soils. Occasional and selective pruning of oldest wood will keep the shrub compact, densely leafed, and tidy; shearing makes it very twiggy (see Guides).
