Black haw is a shrub or small tree of the Adoxaceae family, from 10 to about 20 feet in height, it has rather stout, spreading branches.

The smooth bright-green, finely toothed, broadly or roundish oval leaves are 1 to 3 inches long. The numerous stemless flower clusters are from 2 to 4 inches broad, composed of numerous creamy white flowers appearing from April to June.

The fruit, which is sweet and edible, is about half an inch long, bluish black, covered with a bloom, and ripens in early autumn. It contains a somewhat flattened stone.

The bark is reddish-brown, very rough on old stems. The branchlets are red at first, and then green, finally dark brown tinged with red. The winter buds are coated with rusty tomentum.

Cultivation & Harvesting

considerations for growing black haw

Black haw occurs in dry woods and thickets and on rocky hillsides in sun to part shade. It can also handle a spot with more shade, though there may be less flowers and fruit.

Black haw grows best in rich, moist, well-drained soil.

You can propagate Viburnum prunifolium by germinating the seeds or taking cuttings from an existing shrub.

For growing from seed: seeds are best sown in a cold frame as soon as it is ripe. Germination can be slow, sometimes taking more than 18 months. If the seed is harvested 'green' (when it has fully developed but before it has fully ripened) and sown immediately in a cold frame, it should germinate in the spring. Stored seed will require 2 months warm then 3 months cold stratification and can still take 18 months to germinate.

Transplant the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame or greenhouse. Plant out into their permanent positions in late spring or early summer of the following year.

For growing from cuttings: take cuttings of soft-wood, in early summer. Pot up into individual pots once they start to root and plant them out in late spring or early summer of the following year. These cuttings can be difficult to overwinter, it is best to keep them in a greenhouse or cold frame until the following spring before planting them out.

Can also do layering of current seasons growth in July/August, takes 15 months.

Branch bark of black haw may be collected in summer. The trunk bark should be collected in fall.

Dry the bark in the shade, cut into small pieces and store in a cool dry place.
