Winter hazel (Corylopsis glabrescens var. gotoana)
Corylopsis glabrescens var. gotoana, or Winter hazel, offers unique fragrant yellow blooms in early spring. A low-maintenance deciduous shrub for zones 5-8.
Complete Plant Information
Overview
Corylopsis glabrescens var. gotoana, commonly known as Winter hazel, is a highly valued deciduous shrub prized for its extraordinarily early bloom time, appearing before most other landscape plants awaken for spring. This variety provides essential early color and fragrance when the garden landscape is otherwise barren. As a member of the Hamamelidaceae family, closely related to witch hazel, this shrub offers reliable seasonal interest.
This spreading, multi-stemmed shrub typically matures between 8 and 15 feet tall and wide, fitting well into established shrub borders or woodland garden settings. The growth habit is generally manageable, requiring relatively low maintenance throughout the season once established in optimal conditions. For gardeners seeking alternatives to forsythia that offer superior fragrance, discovering the merits of Corylopsis glabrescens var. Gotoana is highly beneficial.
While the late winter flowers are the main attraction, the plant also provides good texture throughout the summer with its dark green, toothed leaves. Successful cultivation of Winter hazel relies on providing the rich, acidic soil it prefers, though it tolerates average garden conditions better than some related species.

How to Grow
Plant Corylopsis glabrescens var. gotoana in the cooler seasons, fall or early spring, to allow the roots time to establish before summer heat. It thrives best in full sun to partial shade, ensuring it receives protection from the harshest afternoon light if planted in warmer zones. Critical to success is soil preparation; aim for acidic, organically rich, medium-moisture, and well-drained media. While it tolerates average garden soils, performance suffers in heavy, unamended clays.
Water regularly throughout the first growing season to maintain that essential medium soil moisture level. Once established, Water hazel typically requires consistent watering but should not sit in soggy conditions due to its need for good drainage. Pruning is generally light; focus on removing any crossing or damaged wood immediately after flowering, as heavy pruning can reduce the following year’s bloom display.
Be aware of the sensitive nature of the flower buds on Corylopsis glabrescens var. gotoana. In the northern limits of its growing range, placing the shrub in a location sheltered from harsh winter winds can mitigate damage from early spring frosts, which can destroy the nascent blooms. Provide a layer of organic mulch annually to help maintain soil acidity and moisture levels.
Landscape Uses
The primary value of Winter hazel lies in its pre-foliage flowering which perfectly complements plants like early spring bulbs or later-blooming Witch Hazels (Hamamelis). Because it provides structure and early color, it excels when used as a specimen plant near walkways where its fragrance can be easily appreciated. Its spreading, multi-stemmed habit makes it an excellent choice for informal shrub borders, providing a dense screen.
For gardeners looking for a functional application, Corylopsis glabrescens var. gotoana works well when utilized as a natural-looking hedge, offering year-round structure contrasted by its bright yellow display in March. In woodland garden designs, allow it room to spread naturally to achieve its mature, picturesque form. It pairs beautifully with evergreens that provide a deep green backdrop to contrast the pale yellow flowers.

Noteworthy Characteristics
Corylopsis glabrescens, commonly called fragrant winter hazel is native to Japan. It is a spreading, multi-stemmed shrub that typically grows 8-15’ tall and features drooping clusters (hairless racemes to 1.5” long) of fragrant pale yellow flowers in late winter to early spring before the foliage emerges. Var. Gotoana is very similar to the species except for having obovate leaves with short-awned teeth and smaller flowers. The genus name refers to its leaf resemblance to true hazel (Corylus).
Tolerances
- No serious insect or disease problems
Potential Problems
This Winter hazel variety is remarkably resistant to most common garden pests and diseases, which contributes greatly to its low maintenance level. Gardeners should primarily focus on cultural care rather than chemical intervention. The most significant potential issue involves late frosts damaging the flower buds, which can drastically reduce your early spring floral show. Avoid planting in areas prone to late freezes or sudden temperature swings without protection.

Conclusion
The Winter hazel (Corylopsis glabrescens var. gotoana) provides unparalleled early-season fragrance and subtle yellow color, making it a vital component in the winter-to-spring transition garden. Its manageable size and low maintenance requirements seal its value for many landscape applications, from borders to hedges. Before planting, confirm your site provides the acidic, well-drained soil this shrub requires, and try to select a location somewhat sheltered from severe late frosts.
Companion Planting
Selecting appropriate companions ensures your Corylopsis glabrescens var. gotoana thrives while complementing its early bloom time. Acid-loving evergreens provide excellent structure and background color against the drooping yellow flowers. Consider pairing it with rhododendrons, azaleas, or camellias, as they share similar soil pH requirements. If you desire continued spring interest, plant low-growing spring ephemerals like Bloodroot or Squill beneath the canopy to fill in the base once the shrub’s leaves emerge.
Seasonal Care Calendar
Spring care focuses heavily on protection and pruning. Immediately after flowering concludes, apply a light application of slow-release fertilizer formulated for acid-loving plants if your soil is deficient. Pruning should be done in very early spring before new growth starts or immediately post-bloom; avoid fall pruning entirely. Summer watering should be consistent to maintain medium moisture, especially during dry spells, to support root development for next year’s flowers. In autumn, top-dress with a fresh layer of compost or shredded bark to protect the root zone over winter and continue building the critical acidic soil profile for this beautiful Winter hazel.
