Hamamelis × intermedia

Hamamelis x intermedia3

Hamamelis × intermedia is a hybrid species of shrub in the Hamamelidaceae family, known commonly as the intermediate witch-hazel. It is a cross between Hamamelis japonica (Japanese witch-hazel) and Hamamelis mollis (Chinese witch-hazel), combining the desirable characteristics of both parent species. This deciduous shrub is widely appreciated for its vibrant, fragrant flowers that bloom in late winter to early spring, providing color and fragrance when few other plants are active.

Description

Hamamelis × intermedia typically grows to a height of 12 to 15 feet (3.6 to 4.5 meters) and spreads to a similar width. The shrub has a rounded, vase-shaped form, with branches that grow in a somewhat irregular fashion. The leaves are broadly oval, up to 6 inches (15 cm) long, and turn striking shades of yellow, orange, and red in the fall, making it a plant of significant ornamental value throughout multiple seasons.

The flowers of Hamamelis × intermedia are one of its most distinctive features. They appear on bare branches, often while snow is still on the ground, in clusters along the stems. Each flower consists of four narrow, ribbon-like petals, which can be yellow, orange, or red, depending on the cultivar. The flowers emit a spicy fragrance that can be detected from a distance.

Cultivation

Hamamelis × intermedia thrives in full sun to partial shade and prefers well-drained, acidic to neutral soil. It is hardy in USDA zones 5 through 8. The shrub requires minimal pruning, which, if necessary, should be done in spring immediately after flowering to maintain shape and promote healthy growth. It is relatively low maintenance, with few problems from pests or diseases.

Cultivars

There are many cultivars of Hamamelis × intermedia, each with its own unique flower color and form. Some of the most popular include:

• 'Diane' – Noted for its deep red flowers.
• 'Jelena' – Features copper-colored flowers and is known for its exceptional fall foliage.
• 'Arnold Promise' – Renowned for its bright yellow flowers and strong fragrance.

Uses

Hamamelis × intermedia is primarily used as an ornamental plant in gardens and public landscapes. Its ability to bloom in late winter adds color and interest during a time when most other plants are dormant. Additionally, its fragrant flowers and attractive fall foliage make it a valuable addition to the garden throughout the year. It can be used as a specimen plant, in mixed borders, or as part of a woodland garden.

Conservation

As a hybrid species, Hamamelis × intermedia does not have specific conservation issues. However, the preservation of its parent species, particularly in their native habitats, is essential for future breeding and hybridization efforts.
