Additional Information

'Old Heavy Berry' is an excellent, vigorous female cultivar with good winter hardiness and an abundance of large, bright red fruits. This species, like other hollies, is dioecious, so plant females for fruit and an occasional male for pollination. Winter desiccation injury can occur on leaves in exposed sites. Holly leaf miners are one of the major pest problems for Ilex opaca.
