Ilex verticillata: A Vibrant Winter Wonder

Ilex verticillata, or Winterberry, is a deciduous holly native to eastern North America. Unlike its evergreen holly cousins, Winterberry sheds its leaves in the fall, revealing a stunning display of bright red berries that persist throughout the winter months. This hardy shrub provides a vital food source for wildlife and adds a splash of color to the often-drab winter landscape.

Botanical Characteristics

Description:

Winterberry is a deciduous shrub that typically grows to a height of 6 to 10 feet, though it can reach up to 15 feet in ideal conditions.

It has an upright, rounded habit and often forms thickets or colonies.

The bark is smooth and gray.

The leaves are dark green, elliptic to obovate, and have toothed margins.

Flowers:

Winterberry produces small, inconspicuous greenish-white flowers in late spring or early summer.

It is a dioecious plant, meaning that male and female flowers are borne on separate plants.

Pollinators such as small bees and flies are attracted to the flowers.

Fruit:

The most striking feature of Winterberry is its abundant display of bright red berries.

These berries, about 1/4 inch in diameter, appear in late summer and persist throughout the winter.

Only female plants produce berries, and they require a male pollinator to set fruit.

Pruning:

Winterberry can be pruned in early spring before new growth begins.

Pruning helps to maintain the shape of the shrub and encourages berry production.
