One of the fascinating aspects of witch hazel is its unique behavior when it comes to leaf drop during winter. Unlike most deciduous shrubs that shed their leaves in the fall, witch hazel often retains its leaves throughout the winter months, only to drop them when its vibrant flowers emerge in late winter or early spring.
This behavior is not observed in all witch hazel varieties, but it is a characteristic of some species and cultivars. For example, Hamamelis virginiana, commonly known as common witch hazel, tends to hold onto its leaves throughout the winter. Similarly, Hamamelis mollis, also known as Chinese witch hazel, can exhibit this behavior as well.
The retention of leaves by witch hazel during winter can be attributed to several factors. One possible reason is that the leaves provide some protection to the plant against the cold temperatures and drying winds of winter. By maintaining its foliage, witch hazel is able to minimize water loss and protect its delicate branches from potential damage.
In my personal experience, I have observed witch hazel shrubs with their leaves still attached during winter, creating a striking contrast against the barren landscape. These shrubs become a focal point in the garden, adding a touch of color and texture when most other plants have shed their leaves.
It is important to note that not all witch hazel varieties exhibit this behavior. Some cultivars, such as Hamamelis x intermedia ‘Arnold Promise’ or ‘Diane’, are known for their stunning fall foliage, which they shed before winter sets in. These varieties tend to flower in late winter or early spring, when they are completely leafless.
While witch hazel is generally a deciduous shrub, some varieties have the unique ability to retain their leaves throughout winter. This behavior can provide additional protection to the plant and adds visual interest to the winter garden. However, it’s worth noting that not all witch hazel varieties exhibit this behavior, and some shed their leaves in the typical fall fashion.
