Regardless of your gardening style, there are many great shrubs for shade zones. Choosing the right plants for your garden can help ensure that your plant life thrives. In this article, we’ll cover flowering dogwoods, Viburnums, Azaleas, and more. Once you’ve figured out what zone you’re in, you’re ready to start shopping! Whether you’re planting a new garden or just need some inspiration, we’ve got you covered.
Viburnums
In addition to their attractive foliage, viburnums in shade zone four produce flowers that are white or semi-snowball in color. While this variety is self-incompatible, it does best in soil that is slightly acidic, well-drained, and consistently moist. They need deep watering and general-purpose fertilizer, which should be applied in the spring before new growth begins. It is also important to provide good air circulation around the plant to reduce the risk of fungal disease.
Among the best viburnums for shade, the Wright viburnum, or ‘Wentworth,’ produces spectacular foliage in all seasons. Though it is only hardy to zone five in the U.S. Department of Agriculture, this species is a stunning choice for shady spots. This plant will grow to a maximum height of 10 feet, and its glossy green foliage will add a touch of color to your yard or garden.
Another important factor to consider when choosing a viburnum for shade is the pests that affect it. The viburnum leaf beetle is a pest that feeds on many different species of viburnums, and in some cases, it can cause significant damage. While it does not affect viburnums in the Piedmont area, climate change may make it susceptible to its spread. If you suspect that your viburnum is susceptible to viburnum leaf beetles, visit Cornell University or the New York State Integrated Pest Management Program.
Azaleas
After planting, azaleas need regular watering, especially during the spring and summer. Watering is also necessary in winter, when they suffer from dehydration. They need a half-gallon of water per square foot of foliage, while larger shrubs need more than seven to ten gallons of water per week. Make sure to protect your shrub from strong winds and avoid fertilizing it too late in the growing season.
When growing azaleas, remember that they will grow between 12 inches and 12 feet tall. Depending on the variety, you can prune them into a desired shape and size. Deciduous varieties have more upright shapes, while evergreen types have round or irregular shapes. Most azaleas bloom in the spring, lasting two weeks. Some varieties even bloom during the fall, so plan accordingly and choose varieties that can tolerate some shade.
If you want a flowering azalea for zone 4, you can try the ‘Lights’ series. This series is known for its bright, tropical-inspired colors and remarkable flower bud hardiness. Several of the ‘Lights’ azaleas were bred in 1957. Their first introduction, the ‘Northern Lights’, featured fragrant pink flowers.
Clethra
The genus Clethra contains 30 species native to the Americas and eastern Asia. The Clethra alnifolia is a species native to the East Coast and features fragrant, white or pink flowers. Clethra prefers moist, acidic soil and tolerates partial shade. They tolerate a wide range of soil conditions, but do best in moist soil.
The size of Clethra shrubs for shade varies from 3 feet tall to 20 feet tall, and they thrive in moist, acidic soils with organic matter. Since they are naturally found in swampy areas, they require some extra water during the hot summer months. Although they are hardy in USDA zones 3 to 9, they will need additional water in areas with less water than in the summer.
Clethra Taller Than Hummingbird is a variety selected from seedlings of Hummingbird. It features similar flowers, but is more robust, with more upright flower spikes. It is drought-tolerant once established and responds well to fertilizing. Pruning during winter will ensure that flower buds are not removed. The plant will continue to colonize itself as it grows, so keep pruning in mind.
Clethra is another low-maintenance choice for the shade garden. They require only a small amount of granular fertilizer in the spring and will do just fine without it after the first couple of years. Shrubs are also highly water-efficient, but their water requirements vary by variety. Make sure to research the watering requirements of the variety you choose and match their requirements with your soil type.
Flowering Dogwoods
If you’re looking for a beautiful year-round focal point for your yard, flowering dogwood trees may be the perfect choice. These beautiful trees are hardy in USDA zones 5A through 9A. Flowering dogwoods can also be grown in the shade as Japanese Kousa dogwoods. Both species share similar growing conditions, but you will want to take special care when choosing one. Whether you want to make your yard look stunning or reduce maintenance, flowering dogwoods are a great choice for the shaded areas of your garden.
Flowering dogwoods are popular ornamental trees and shrubs. They are fast-growing woody subshrubs and trees that die back to the ground during the winter, only to grow back from buds at the base. Flowering dogwoods are a great choice because they provide year-round interest, are easy to grow, and require little maintenance. Native to the northeastern United States, flowering dogwoods are available in dozens of cultivars for a variety of purposes.
There are many types of flowering dogwoods for shade zones, including the Red Edible Dogwood. For a Southern garden, Spring Glow is a great choice. This species grows 20 feet tall and 15 feet wide. In the spring, its fragrant, yellow flowers attract birds and butterflies. Red Edible Fruit appears in July. Flowering dogwoods are great shade-tolerant trees and also have good disease resistance.
Euonymus fortunei
Euonymus species differ widely in their vigor and growth habits. Some are native to temperate climates, while others grow in a variety of climates, including the shade zone 4b – 8. The euonymus species is an excellent choice for shade gardens, because of their adaptability to a wide range of soil types and growing conditions. However, if you’re planting your Euonymus in a shade garden, you should consider their spacing requirements and other considerations.
While the majority of euonymus species are green, a few varieties have variegated foliage. Gold Splash, for example, has green leaves but a variegated appearance that contrasts nicely with the rest of the plant. This plant is highly adaptable to pH levels and can tolerate heavy shade for several years. As with many shade plants, Euonymus fortunei is prone to several common pest and disease problems, but most maladies can be treated by repeating the treatment.
The spread of spreading euonymus varies considerably. It is typically 8 to 12 feet tall but is more commonly grown as a variety called Manhattan. Its blooms vary depending on the variety and zone. It is hardy in zones five to eight. There are different bloom times for different varieties. Most species bloom from late summer to late fall. So, if you want to grow a Euonymus fortunei in shade zone 4, you should choose a variety that blooms in a shorter timeframe than its rivals.
Snowberry
Snowberry shrubs are hardy plants that will survive in shade zones 4 and 5. They produce berries that are essential for wildlife during the winter, but the seeds are quite difficult to germinate. Therefore, it is best to overwinter them indoors. During the summer, they will flourish in partial shade. However, if you are looking for a hardy shrub, you may want to consider one of the species listed below.
One of the most common snowberry shrubs, S. albus, is native to the eastern and western United States. It has attractive waxy white flowers and thin, wiry branches that make it a good plant to grow in a garden. Its flowers are also attractive to humans. In fact, it is one of the most popular shrubs in gardens. Those who live in sunny climates can grow it as a shade-tolerant specimen.
Another important species, snowberry, is the Pearl tree. The berries are white or pink, and the plant holds onto them through the winter. It grows well in pots, shrub beds, and standalone locations, and is a good choice for planting alongside a riverbed. In addition, the stems make for lovely fall arrangements. The plants are also great for banks stabilization projects. They provide wildlife habitat, and can tolerate a range of soil conditions.
