Winter Red
Ilex verticillata 'Winter Red'
shrubWinter Red is a deciduous holly cultivar prized for its abundant bright red berries that persist well into winter, providing striking ornamental interest and wildlife food.

The dense branching habit and prolific fruiting make it an excellent choice for winter landscapes and bird gardens.

Establishment (Year 1)
12 monthsYoung plant focuses on root development with minimal branching above ground
Water consistently, mulch around base, avoid fertilizing heavily, support with stakes if needed in windy areas
Vegetative Growth (Years 2-3)
24 monthsDense branching develops with glossy green oval leaves; plant grows 12-24 inches per year
Prune lightly after bloom to shape; ensure adequate moisture; maintain acidic soil; no heavy pruning needed
Flowering (Spring)
3-4 weeksTiny white four-petaled flowers appear on female plants in clusters; male plants needed for pollination
Male pollinator plant (like 'Jim Dandy') should be nearby; do not spray pesticides during bloom
Berry Development (Summer-Fall)
4-5 monthsFertilized flowers develop into bright red berries that ripen fully by October; foliage turns burgundy-red before leaf drop
Maintain consistent moisture; avoid pruning heavily; berries persist through winter; no intervention needed
Winter Display (Fall-Winter)
4-5 monthsDeciduous shrub drops leaves, revealing abundant bright red berries on bare branches through winter months
Minimal care; enjoy ornamental display; berries feed wildlife; light pruning acceptable if needed

Uses
Winter Wildlife Food
WildlifeThe abundant bright red berries provide essential food for robins, cedar waxwings, and other songbirds during winter months when other food sources are scarce. A single Winter Red shrub can support dozens of birds. [source]
Festive Holiday Décor
HouseholdCut berry-laden branches make stunning winter and holiday floral arrangements and decorations indoors in vases or as mantelpiece displays. Branches last 2-3 weeks in water. [source]
Herbal Tea (Use with Caution)
CulinaryWinterberry has been used traditionally in some Native American herbal preparations, though berries are mildly toxic and should be avoided. Leaves were historically used for beverages, though modern use is limited. [source]
Natural Landscape Design
CraftWinter Red's seasonal color transformation—green summer foliage to burgundy fall leaves to scarlet winter berries—makes it essential for four-season interest and natural, wildlife-friendly landscape designs. [source]
Traditional Medicine (Historical)
MedicinalNative Americans and early colonists used winterberry leaves in teas and preparations for digestive and fever treatments, though modern herbalism does not widely recommend this due to safety concerns. [source]

Harvest Tips
Winter Red is ornamental; do not harvest berries for consumption (they're slightly toxic to humans). Cut branches with berries for winter floral arrangements anytime from October through February while berries are still firm and colorful. Harvest early morning for longest vase life. Allow berries to remain on plant for wildlife feeding.
Fun Facts
- 🌱 Winter Red is dioecious, meaning separate male and female plants are required for berry production—a single female shrub won't fruit without a male pollinator nearby (like 'Jim Dandy' or 'Raritan Chief')
- 🌱 The berries remain bright red and attractive to birds because they're too sour and astringent for most mammalian predators, so birds wait until winter when other food is scarce and the berries become softer and more palatable
- 🌱 Despite the common name 'winterberry,' this is a deciduous holly that loses its leaves in fall—unlike evergreen hollies—making the red berry clusters appear to float in mid-air on bare branches, creating dramatic winter interest
