Botanical Name : Viburnum rufidulum
Synonyms: V. prunifolium ferrugineum. V. rufotomentosum.
Common Names: Rusty blackhaw, Blue haw, Rusty nanny-berry, or Southern black haw
Habitat :Viburnum rufidulum is native to Southern N. America – Virginia to Florida, west t Texas, Oklahoma and Kansas. It grows on moist woods and thickets. By the sides of streams, hillsides, roadsides, woodland margins and clearings. Also found in dry upland woods.
Viburnum rufidulum is a deciduous Shrub growing to 12 m (39ft 4in). Leathery deciduous leaves are simple and grow in opposite blades ranging from 0.5-3 inches in length and 1-1.5 inches in width. Petioles are “rusty hairy” with grooves and sometimes wings. Leaf margins are serrate. Autumn leaf colors are bronze to red.
Twigs range in color from “reddish brown to gray”; young twigs are hairy, and get smoother with age.
Bark is similar that of the Flowering Dogwood, ranging in color from “reddish brown to almost black” and forming “blocky plates on larger trunks”.
V. rufidulum blooms in April to May with creamy white flowers that are bisexual, or perfect and similar to those of other Viburnum species, but with clusters as large as six inches wide. The seeds ripen from Aug to October.
The fruits are purple or dark blue, glaucous, globose or ellipsoid drupes that mature in mid to late summer. The fruit has been said to taste like raisins and attract birds….CLICK & SEE THE PICTURES
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
An easily grown plant, it succeeds in most soils but is ill-adapted for poor soils and for dry situations. It prefers a deep rich loamy soil in sun or semi-shade. Best if given shade from the early morning sun in spring. A fast-growing but short-lived species in the wild. Plants grow well but do not flower very freely in Britain. Plants are self-incompatible and need to grow close to a genetically distinct plant in the same species in order to produce fruit and fertile seed.
Seed – 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. Prick out 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. Cuttings of soft-wood, early summer in a frame. Pot up into individual pots once they start to root and plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood, 5 – 8 cm long with a heel if possible, July/August in a frame. Plant them into individual pots as soon as they start to root. 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. Cuttings of mature wood, winter in a frame. They should root in early spring – pot them up when large enough to handle and plant them out in the summer if sufficient new growth is made, otherwise keep them in a cold frame for the next winter and then plant them out in the spring. Layering of current seasons growth in July/August. Takes 15 months.
Edible Uses: …..Fruit – raw or cooked. The fleshy fruit has a sweet taste, somewhat like raisins, but it is nearly all seed. The taste is best after a frost. The ellipsoid fruit is up to 15mm long and contains a single large seed.
Medicinal Uses:..Antispasmodic……The bark is antispasmodic and has been used in the treatment of cramps and colic.
Other Uses :…Wood…….Wood – fine-grained, heavy, hard, strong, with a disagreeable odour. Of no particular value. It is occasionally used as an ornamental plant. It was used to cure rust.
