What Are Winterhazel Plants?
Belonging to the Hamamelidaceae family, winterhazels are a group of deciduous woody shrubs that encompass 25 species from the Corylopsis genus. These plants are hardy in USDA Zones 6 to 8, with some species like C. glabrescens tolerating Zone 5 as well.
Originating from East Asian countries such as China, Japan, and Taiwan, winterhazels thrive in clearings, woodlands, and mountainous slopes. Known for their multi-stemmed forms and slow growth rates, these shrubs boast smooth bark in shades of tan, brown, or gray.
One of the most striking features of winterhazels is their early-blooming flowers, which appear in clusters of fragrant, pale gold to greenish-yellow blossoms. These flowers are not only attractive to the eye but also draw in butterflies and hummingbirds.
Cultivation and History
The genus name Corylopsis, meaning “hazel-like,” perfectly describes the resemblance of winterhazel leaves to those of true hazel plants. Introduced to western horticulture during the late 19th and early 20th centuries, winterhazels have become popular among temperate gardeners for their beauty and early bloom times.
Winterhazel Propagation
When it comes to propagating winterhazels, taking cuttings from mature plants or transplanting juvenile specimens are the recommended methods. While sowing seeds can be done, it involves intricate temperature treatments and years of patience, making it less suitable for beginners.
From Cuttings:
– Take four- to six-inch cuttings from healthy shoots in summer.
– Root the cuttings in a rooting hormone and a soilless mix indoors.
– Once rooted, transition the cuttings outdoors after the final frost date.
Transplanting:
– Prepare planting sites with well-draining soil after the first frost-free date.
– Plant transplants by mixing humus with the soil and providing ample water.
How to Grow Winterhazel
For successful growth of winterhazel shrubs, consider the following factors:
Climate and Exposure Needs
Winterhazels prefer full sun to partial shade, with exposure depending on the climate and landscape requirements. While more sunlight results in better blooms, protection from wind is vital, especially during late winter.
Soil Needs
Ensure well-draining, organic soil with a slightly acidic pH for optimal growth. Incorporating humus into the root zone annually can help maintain soil quality.
Water Needs
Moderate moisture is preferred for winterhazels, with deep watering required when the topsoil dries out. Avoid excessive watering to prevent root rot.
Growing Tips
To ensure healthy growth of winterhazels, keep these tips in mind:
* Provide protection from wind for optimal bloom development.
* Amend the root zone with organic matter each spring.
* Water plants when the topsoil feels dry to the touch.
Pruning and Maintenance
Routine maintenance of winterhazels involves removing dead or damaged tissues promptly. If shaping is desired, prune up to a third of the plant’s mass after flowering. Consider using trimmed branches for indoor floral arrangements to enjoy the plant’s scent.
Winterhazel Species to Select
With 25 species of Corylopsis to choose from, selecting the right winterhazel can be a delightful experience. Here are three top picks:
1. Buttercup:
– Native to western Japan and Taiwan.
– Features pale yellow blooms and bright green leaves with distinct veining.
– Impressive mature height and spread of four to six feet.
2. Fragrant:
– Hails from Japan and is hardy in Zones 5 to 8.
– Known for its strong-scented, pale yellow blooms.
– Reaches heights and spreads of eight to 15 feet.
3. Spike:
– Native to Japan with a mature height of four to eight feet.
– Colorful blooms with purple, red, and yellow hues.
– Leaves emerge in purple, maturing to blue-green.
Managing Pests and Disease
Winterhazels are relatively resistant to pests and diseases, but Japanese beetle infestations and root rot are potential issues to watch out for.
Japanese Beetles:
– Control through manual removal or insecticides like neem oil or pyrethrin-based sprays.
– Soapy water buckets can be used for physical removal of beetles.
Root Rot:
– Prevent by ensuring well-draining soil and avoiding overwatering.
– Inspect roots for rot and replant in better-draining areas if necessary.
