The Viburnum Blackhaw

Blackhaw Viburnum (V. prunifolium) The rounded, stiffly branched habit of Blackhaw viburnum reminds you of a Hawthorn. Other common names are Sloe, sloe-leaved viburnum, stagbush, shonny. It can be grown as a small tree because plants attain a height of 12 to 14 feet. The dark green, glossy, leathery leaves turn a dark reddish to purple in the fall. Creamy white flowers are borne in flat-topped flower clusters during May. The fruit turns blue-black at maturity. The fruit, which is sweet and edible, is nearly half an inch long, bluish black, covered with a bloom, and ripens in early autumn. It contains a small and somewhat flattened stone. The mature fruit make good preserves. The leaves are small enough that they don't pose a raking and cleaning problem. Birds frequent this shrub for feed and shelter. Plants are native and tolerate shade but flower and fruit best in full sun.Habitat and range.The blackhaw occurs in dry woods and thickets and on rocky hillsides from Connecticut to Florida and west to Michigan and Texas, but is mostly found in the South. On our plant durability list, we rate this a 9 for ease of transplanting and site adaptability. There are also few serious pests that homeowners need to concern themselves with. We have seedling, transplants, and B&B plant to 4'. Blackhaw viburnum be found in woods and thickets in moist or dry soil. Blackhaw viburnum is a round-headed tree or multi-stemmed shrub. This plant has a coarse aspect in winter. The late fall color varies from plant to plant, from purplish, to reddish purple, bronze, dull deep red to red. The flowers can appear creamy rather than white. Although it will tolerate some sun, blackhaw viburnum is best used as a medium understory or edge of the woods plant. In the landscape this plant can adapt well to locations that don't get full sun such as a shaded side yard that needs a border or screen buffer. Clay soils that are moist can be planted with this plant. This plant is hardy to zone three. We feel thatViburnums are an attractive, versatile, adaptable plant choice for any landscape. They can be used as hedges and screens and in shrub borders. They can also stand as specimen plants. They are usually in the form of shrubs, but can become small trees.(sieboldi) They range in size from the small Dwarf American Cranberry at 2 feet tall by 2 feet wide, to the Siebold at over 15 feet tall. Viburnums are plants with year round interest. Viburnums have white to pink flowers in the spring. Some are fragrant. They have large, attractive and often textured leaves. Some viburnums have wonderfully fragrant flowers that are produced in snowball like clusters in the spring. The flower clusters can be of pink buds, which develop into white flowers. Some fruits are red and turn black with age. Leaves are glossy, dark green and turn a burgundy color in the fall. Midsummer berries are an important food source for birds. Viburnums are a must for the avid birder. Viburnums can have colorful red to purple leaves. Some viburnums can become medium-size trees, especially if they are pruned. Viburnums are specimen plants or as anchors in mixed borders and hedges. You won't find a more versatile group of shrubs for hedges or for massing in groups, since viburnums hold their own in every season and landscape. Some viburnums, such as Prague viburnum, are evergreen and have fragrant flowers. Others, such as leatherleaf viburnum, are semi-evergreen in colder climates, losing their leaves when temperatures dip below 10 degrees. We like Viburnums because of their adaptability and durability. While they would prefer full sun and moderately watered, well-drained rich soils, they grow very well in part shade in alkaline, clay soils. Diseases and pests are not common for viburnums. We have more trouble from my kids running over them with brush hogs. They claim they were testing their durability. Yet all the viburnums they chopped to the ground survived. In fact, we sold these plants for a premium as they produced better numbers of desireable stems. Their fibrous root system makes them transplant and propagate easily. (We do have more difficulty with the Korean Spice rooted cuttings.) If you are shopping for a sharp hardy shrub consider one of the many cultivars of the Viburnum family. In fact select a couple of them. You will be rewarded with shrubs with all season interest. Viburnums have long been popular garden plants, known for their white, often fragrant spring flowers and their fall color. But it's the Asian viburnums that are prized. Perhaps the most widely known viburnums are the Burkwood viburnum (Viburnum x burkwoodii), and the Korean spice viburnum (V. carlesii), both of which fill the air with an enchanting clovelike aroma in mid-spring. (The Mohican is a cross of the two.) Also popular is the doublefile viburnum (V. plicatum f. tomentosum), valued for its layered habit, fall foliage, and clusters of red fruits, and its close relative the Shasta, a gold medal winner. Viburnum acerifolium (Maple-leafed viburnum) Although I wouldn't garden without any of these, I have a special fondness for native viburnums. They may not provide the flower fragrance of their Asian counterparts, but I love them for their fall foliage color and for their fruit displays, which attract birds to my garden in the fall and winter months. In addition, several are useful to waterwise gardeners or in urban conditions. They require only corrective pruning, and none commonly suffer from pests or diseases. Viburnums are considered moist woodland plants. In nature they are found along steam banks from Long Island to Florida. When you come to our 5275 West Swamp Rd. location ask us to show some in their native habitat that we found along our stream bank. These plants perform well under normal landscape conditions. I especially like the floral display in the spring and these viburnums that bear fruit in the fall. Winterthur has great red leaves and abundant fruit in the fall. This cultivar needs a cross pollinator such as viburnum nudum. Native Americans used Viburnum dentatum (arrowwood viburnum) for arrow shafts. There stems are long and strait. This plant will grow in places many plants struggle. So if you have had trouble with plants in a harsh location try this cultivar. Viburnums We raise over 10 types of Viburnums on our farms from seedlings to 5' shrubs. If you have poor soils due to compacting from construction, try viburnums. Being rugged and hardy, they perform where other plants fail.
