Origin
Viburnum nudum L. var. serotinum Ravenal ex Chapman is a flowering plant species that belongs to the Adoxaceae family. It is native to the southeastern United States, found in states such as Florida, Georgia, and the Carolinas.
Common Names
This plant has several common names, including smooth witherod, possumhaw, and wild raisin. Its scientific name, Viburnum nudum L. var. serotinum Ravenal ex Chapman, is not often used in everyday language.
Uses
The smooth witherod has several uses. Native Americans used the plant's bark, leaves, and roots to treat various ailments like fever and stomach pain. The berries of the plant, sometimes known as wild raisins, are edible but can cause stomach upset if consumed in large quantities. Birds are a primary consumer of the berries, making them an important food source for local wildlife. The plant is also ornamental and is occasionally used in landscaping as a hedge or screening plant due to its large size and attractive foliage and blooms.
Appearance
The smooth witherod is a deciduous shrub that can grow up to 12 feet tall and wide if left unchecked. The leaves are glossy and green, with an elliptic or ovate shape and lightly toothed margins. In the fall, the leaves turn shades of red, yellow, and purple, adding a burst of color to autumn landscapes. The plant produces flat-topped clusters of small white flowers in late spring or early summer, which mature into spherical berries that shift in color from green to pink to blue-black.
Light Requirements
Viburnum nudum L. var. serotinum Ravenal ex Chapman typically grows well in full sun to partial shade conditions. It requires at least 4-6 hours of direct sunlight each day to thrive. However, it can also tolerate some amount of shade and may thrive better in a partially shaded location.
Temperature Requirements
This plant is native to the southeastern United States and is typically grown in USDA hardiness zones 5 to 9. It prefers moderate temperatures and can tolerate some frost, but cannot survive in extreme cold. The ideal temperature range for Viburnum nudum L. var. serotinum Ravenal ex Chapman is 60-70°F during the day and 45-50°F at night.
Soil Requirements
Viburnum nudum L. var. serotinum Ravenal ex Chapman grows best in well-draining soil with a pH range of 5.5 to 6.5. It can tolerate different soil types, including sand, clay, and loam, as long as they are well-draining. It prefers slightly moist soil but can tolerate some drought. Adding organic matter such as compost or aged manure to the soil can help improve soil condition and provide necessary nutrients for growth.
Cultivation methods
Viburnum nudum L. var. serotinum Ravenal ex Chapman, also known as the smooth witherod, is a deciduous shrub that is widely cultivated for its ornamental features and as a wildlife plant. It is easy to grow and can thrive in a variety of soil types as long as the soil is well-drained and moist. The plant prefers full sun to partial shade but can tolerate full shade. Propagation can be done through stem cuttings or by seed sowing. It is best to plant this species in the fall or early spring to allow it to establish before the onset of summer heat.
Watering needs
The Viburnum nudum L. var. serotinum Ravenal ex Chapman requires regular watering, especially during the first few growing seasons. It is important to ensure that the soil is consistently moist but not waterlogged. A good rule of thumb is to water the plant deeply once a week, especially during prolonged periods of dry weather. Avoid overhead watering, as this can lead to the development of leaf spot disease and other fungal infections.
Fertilization
Fertilization is an essential aspect of Viburnum nudum L. var. serotinum Ravenal ex Chapman care. Apply a slow-release fertilizer in early spring to encourage healthy growth and abundant flowering. A balanced fertilizer with an NPK ratio of 10-10-10 is ideal. Avoid applying too much fertilizer, as this can lead to leaf burn and reduced flowering.
Pruning
Pruning is an essential aspect of Viburnum nudum L. var. serotinum Ravenal ex Chapman care. Prune the plant in late winter before new growth emerges to remove any dead, damaged, or diseased branches. Cut back any overgrown branches to encourage a more compact plant form. Avoid pruning the plant after the onset of spring growth, as this can reduce flowering and lead to stunted growth.

Var. Serotinum Ravenal ex Chapman
Viburnum nudum L. var. serotinum Ravenal ex Chapman, commonly known as smooth withered, is a species of plant that belongs to the Adoxaceae family. This plant species can be propagated through different methods, such as seed, cuttings, and layering.
Seed
Propagating Viburnum nudum L. var. serotinum Ravenal ex Chapman through seed is possible, but it can take a long time before the plant reaches maturity. This method requires scarifying the seed coat and stratifying the seed for 3 to 4 months at 41 degrees Fahrenheit before sowing.
Cuttings
Cuttings from Viburnum nudum L. var. serotinum Ravenal ex Chapman are a reliable and faster way to propagate the plant. The cutting material should be taken during the dormant season, from November to February in the Northern Hemisphere. The cuttings should be about 4 inches long, with at least two pairs of buds, and treated with rooting hormone before planting in a well-draining medium such as perlite, vermiculite, or sand. The cutting should be kept under high humidity until roots develop, which may take up to three months.
Layering
Layering is another method of propagating Viburnum nudum L. var. serotinum Ravenal ex Chapman. This method requires bending a flexible stem to the ground and covering a section of it with soil, leaving only the tip exposed. The buried section of stem will develop roots while still attached to the mother plant, and can then be separated and planted as an independent plant once established.
Disease Management
Viburnum nudum L. var. serotinum Ravenal ex Chapman is susceptible to various diseases, including powdery mildew, leaf spot, and bacterial leaf spot. Powdery mildew forms a white, powdery substance on leaves while leaf spot appears as dark spots on leaves. Bacterial leaf spot, on the other hand, results in water-soaked spots on leaves which might worsen and turn into brownish-black scabs on the stems and leaves. Maintaining healthy plants by pruning dead and damaged branches, providing good air circulation, and keeping the plants dry can help prevent diseases. Fungal sprays and copper-based fungicides can also be used to manage diseases.
Pest Management
The plant is infrequently attacked by pests, but some pests such as viburnum leaf beetles, scale insects, and spider mites may attack it. Viburnum leaf beetles eat the leaves, leaving behind larvae that feed on the plant's structure. Scale insects sap the plant's energy and life by depositing honeydew on the plant, while spider mites pierce the plant cells and suck sap from the plant's cells. Beneficial insects such as ladybugs can be used to control pests. Other forms of pest management include pruning and removing affected or infested branches, spraying the plants with neem oil, insecticidal soap, or horticultural oil.
