Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

Fruit ripens to a bluish-black, sweet, raisin-like pulp over a single flattened stone — good eaten fresh off the shrub once fully ripe, though the thick skin and large seed limit it mostly to jam, sauce, or leather.

Spacing
150 cm (59 in) apart — about 2.3 m² (24 sq ft) per plant
Leaf shape
Opposite, oval, 5–10 cm long, wedge-shaped to rounded at the base, with a pointed tip and finely serrated margins; leaf stalks are often slightly winged.
Root system
Spreading, suckering root system that sends up new shoots at some distance from the main stems; old arching branches can also root where they touch the ground.
Fruit description
Oval drupes to about 15 mm, blue-black with a waxy bloom in flat-topped clusters on red stalks; pulpy, very sweet, and juicy but with a thick skin and one large flattened seed.
Propagation
By seed (which typically shows double dormancy and needs warm followed by cold stratification, often taking two years to germinate), by softwood or hardwood cuttings, or by removing rooted suckers.
Pollination
Self-fertile but BETTER WITH A PARTNER — plant 2 cultivars

Growing guide

Fertilizing. Undemanding in average garden soil; an annual spring topdressing of compost is usually enough, since excess nitrogen encourages leggy growth at the expense of flowering and fruit.

How it spreads. Suckers from the base and roots, gradually forming a broad multi-stemmed thicket if unpruned; can also be trained as a small single-trunk tree.

Growing tips. Cold-hardy to about USDA zone 2 and one of the more shade-tolerant viburnums, tolerating a wide range of soil textures, moisture, and pH, plus heat and drought once established. Not self-fertile — plant two or more seedlings or a second cultivar for reliable fruit set. Watch for viburnum leaf beetle, powdery mildew in still, humid sites, and bacterial leaf spot.

About the data

Zone figures are typical published ranges — microclimate, drainage and siting shift them by a zone in either direction. Store links are found by an automated search, refreshed every six weeks. Availability is seasonal; stock and prices are not tracked.
