Ilex verticillata ‘Winter Red’ #3 (Female Winterberry Holly)

‘Winter Red’ is a cultivated variety of our native female Winterberry Holly (Ilex verticillata). The male pollinator needed for this variety is called ‘Southern Gentlemen’. This selection is more floriferous and fruitful than the straight species, with slightly larger berries (to 3/8″) clustered heavily along the twigs. The berries maintain their gorgeous, bright red long into winter, providing a cheerful pop of color in the depths of the season.

‘Winter Red’ prefers moist, acidic soil in partial to full sun which will produce the best flowering and fruit set. Both sexes are necessary for fruit production, but one male plant will suffice for up to six female plants if they are within reasonable flying distance (~50ft) for the bees that cross-pollinate them. They are fairly adaptable to average garden conditions and will perform well in most soils that receive adequate moisture, although chlorosis can be an issue in high pH soils and it will sometimes abort berries in sites that are too dry.

These lovely hollies are a good choice for low or poorly drained areas of the landscape and for planting along damp woodland borders, pond margins and in shrub borders. They are attractive foundation shrubs, and look especially good when planted in groups. The deciduous nature of this species allows the ruby-red berries to shine throughout the winter, adding an unbeatable ornamental effect to any landscape.

*Holly Berries are TOXIC to humans if ingested.
