Description
Corylopsis Glandulifera, commonly known as the winter hazel or glandular winter hazel, is a deciduous shrub native to Japan and Korea. It is a member of the Hamamelidaceae family, which includes other popular plants such as witch hazel and sweet gum. The shrub typically reaches a height of 8-10 feet and a width of 6-8 feet at maturity. In late winter or early spring, it produces clusters of fragrant, pale yellow flowers that hang from the branches like tassels. The flowers are followed by small, brownish-black fruit that are not particularly ornamental.

Appearance
Corylopsis Glandulifera has a spreading habit with arching branches that give it a graceful, weeping appearance. The leaves are alternate, simple, and ovate or oblong in shape, with a glossy dark green color that turns yellow in the fall. The flowers appear before the leaves, usually in late February or early March, and are made up of four or five petals that are fused at the base. They have a light, sweet fragrance and are a welcome sight in the late winter landscape. The fruit that follows the flowers is a small, dry capsule that splits open to release the seeds.
Care Guide
Corylopsis Glandulifera is a relatively low-maintenance shrub, but it does have some specific care requirements to keep it healthy and looking its best. Here are some tips for caring for your winter hazel:Water: Winter hazel prefers consistently moist soil, so water regularly during dry spells to keep the soil evenly moist.Fertilization: Apply a balanced fertilizer in early spring before new growth begins to promote healthy growth and flowering.Soil: Winter hazel prefers well-draining, acidic soil that is rich in organic matter. If your soil is heavy or clayey, amend it with compost or peat moss to improve drainage.Sunlight: Winter hazel prefers partial shade to full shade, especially in hot climates. Too much sun can scorch the leaves and reduce flowering.Hardiness Zones: Corylopsis Glandulifera is hardy in zones 6-8.
Common Pests & Diseases
Winter hazel is generally pest and disease-resistant, but it can be susceptible to a few problems:Aphids: These tiny insects suck sap from the leaves and can cause distortion and yellowing. Treat with insecticidal soap or neem oil.Leaf spot: This fungal disease causes brown or black spots on the leaves. Remove infected leaves and treat with a fungicide if necessary.Verticillium wilt: This fungal disease causes yellowing, wilting, and eventual death of the plant. There is no cure, so infected plants should be removed and destroyed to prevent spreading to other plants.

In cultivation, it prefers similar conditions, with moist, well-draining soil and partial to full shade. It is a good choice for woodland gardens, shade borders, or as an understory plant beneath taller trees.
