Winter Red

Deciduous holly whose bare winter branches blaze with red berries.

Winter Red belongs to the winterberry holly, grown for its winter berries and the reliable structure it brings to the garden year-round. Below is a full profile of Winter Red — its characteristics, how to grow it, whether it needs a pollinator for berries, and answers to the questions gardeners ask most.

About Winter Red

As one of the winterberry holly, Winter Red carries the traits gardeners look for in the group. Ilex verticillata is the deciduous holly grown for one spectacular effect: after its leaves fall, bare branches blaze with dense red or gold berries all winter.

Winter Red is deciduous and hardy across USDA zones 3-9, so it suits a wide range of gardens with the right acidic, well-drained soil and seasonal care.

Characteristics and form

Winter Red makes a rounded, multi-stemmed deciduous shrub, typically around 6-9 ft tall and 3 to 8 feet wide by cultivar. Its foliage is plain green summer leaves that drop in fall to reveal the fruit. Knowing a holly's mature size and habit is the key to placing it well: give Winter Red room to reach its full spread without crowding, which also keeps air moving through the plant and disease at bay.

Berries and pollination

Winter Red is a female holly, so it carries the red berries — but only when a compatible male holly flowers within about fifty feet. Bees move the pollen; without a male in range, a female holly still flowers but sets little or no fruit.

Remember: holly is dioecious — male and female flowers grow on separate plants, and only pollinated females bear fruit. See our full guide to holly berries and pollination for how to guarantee a berry crop.

How to grow Winter Red

Plant Winter Red where it will get full sun to part shade in acidic, moist, well-drained soil. Full sun gives the densest growth and the heaviest berry set. Set the plant at the depth it grew in the pot, water it deeply while it establishes, and mulch the root zone to hold moisture and keep the soil cool and acidic.

  • Light: Full sun to part shade; full sun gives the densest growth and the most berries.
  • Soil: Acidic, moist, and well-drained, ideally pH 5.0–6.5. Improve heavy or alkaline ground with organic matter and keep it mulched.
  • Water: Deep, regular watering while establishing; steady summer moisture helps hold the berry crop.
  • Feeding: An acid-forming holly fertilizer in early spring keeps the foliage deep green.
  • Pruning: Shape in late winter, before growth begins, to preserve the flowers that become berries.

Where to use Winter Red in the garden

Winter Red suits winter-interest plantings, wet and rain-garden sites, cut branches for arrangements, and bird gardens. Site a female such as Winter Red where its bare, berry-laden winter branches show against evergreens or snow, with a matched male nearby.

Common problems and care

Winterberry loves moist to wet, acidic soil and full sun for the heaviest fruit, and is the most cold-hardy of the popular hollies. Watch for the usual holly troubles — leaf miner, scale, and spider mites, and root rot in soggy ground — and head them off with the right site, good drainage, and good air flow. Yellowing leaves usually signal alkaline soil or poor drainage rather than disease.

Winter Red — frequently asked questions

How big does Winter Red get?

Winter Red grows into a rounded, multi-stemmed deciduous shrub, typically reaching 6-9 ft tall and 3 to 8 feet wide by cultivar. Its final size depends on your climate, the site, and how you prune it.

Does Winter Red have berries, and does it need a male holly?

Winter Red is female and bears red berries, but it needs a compatible male holly flowering within about fifty feet to pollinate it. One male can pollinate several nearby females.

Is Winter Red evergreen or deciduous?

Winter Red is deciduous — it drops its leaves in fall, which on a berrying holly reveals the fruit for a striking winter display.

What hardiness zones does Winter Red grow in?

Winter Red is hardy in USDA zones 3-9. That range describes the winter cold it can survive; gardeners colder than zone 3 should give it a sheltered site or choose a hardier holly.

Is Winter Red easy to grow?

Winterberry loves moist to wet, acidic soil and full sun for the heaviest fruit, and is the most cold-hardy of the popular hollies. Give Winter Red an acidic, well-drained soil and the ordinary seasonal care any holly appreciates, and it is a straightforward, low-maintenance shrub.

When should I prune Winter Red?

Prune Winter Red in late winter, while it is dormant and before spring growth begins — that shapes the plant without removing the flower buds that become the next season's berries.
