Ilex verticillata aka Winterberry

Taxonomy

Genus Ilex Family Aquifoliaceae Order Aquifoliales Class Magnoliopsida Phylum Tracheophyta
Ilex verticillata, also known as winterberry, is a native species of holly found in eastern North America. It can be found in wetland habitats, dry sand dunes, and grasslands. This dwarf, upright deciduous shrub has glossy dark green foliage and a rounded habit. While it produces small white flowers in the spring, it is a male cultivar and does not bear berries. However, it can pollinate female cultivars like 'Berry Poppins' to enable them to produce fruit. Winterberry is a valuable addition to the landscape, especially in northern climates where winter can be dreary. Its bright red berries persist throughout the winter and into spring, adding vibrant color. These berries also attract birds, such as the American robin, making it an important food resource. Unlike other holly shrubs, winterberry is deciduous, allowing its berries to take center stage as winter arrives. It is important to note that winterberry can be invasive in the US and may have an aggressive root system in other regions.

Winterberry, Black Alder, Virginia Winterberry

How to care for Winterberry

Difficulty

Winterberry is a low-maintenance plant that requires minimal attention, making it an excellent choice for beginners.

Water

Winterberry should be watered regularly, allowing the soil to dry out between waterings.

Soil

When growing Winterberry, it is important to pay attention to the soil type you are using. This plant is very sensitive to dry soil and needs a potting soil that retains moisture. A good soil should still be well-draining and contain lots of organic matter. Coco coir or sphagnum moss are great options to provide the Black Alder with the nutrients and moisture it needs. The added organic matter will also help the soil retain water and prevent the Winterberry from drying out too quickly. Before planting, make sure to mix compost or manure into the soil for extra nutrients. Also, make sure to water the Winterberry regularly, making sure to keep the soil evenly moist but never soggy. With the correct soil and watering regimen, the Winterberry will thrive and bring lots of beauty to your home.

Lighting

To ensure optimal growth, the Winterberry prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Dormancy

During the cold period, it is common for Winterberry to go dormant and their growth may slow down, so waterings should be spaced out more during this period.

Toxicity

Winterberry is poisonous if ingested. We suggest keeping this plant out of reach if you have children, cats, or dogs in the home.

Fertilizer

The growth of Winterberry is not rapid and it doesn't necessitate any extra fertilization. By replacing its potting soil once a year, it should receive ample nutrition. It is important to note that plants obtain their energy from the sun's rays, not from fertilizers.

Growth-pattern

The Winterberry is clumping in nature, with new growth originating from the soil in close proximity to the original plant.

Region of origin

Winterberry’s native range is Eastern N. America - Newfoundland to Minnesota and south to Georgia and Tennessee..
