Male Holly
Ilex spp.
shrubMale holly cultivars are ornamental evergreen shrubs prized for their glossy foliage and dense branching structure. Unlike female hollies, male plants produce showy flowers but no berries, making them excellent for screening, hedges, and ornamental landscapes. They are hardy, low-maintenance, and provide year-round visual interest.

Fun Facts
- 🌱 Male hollies produce showy fragrant flowers to attract pollinators but never bear berries, making them a practical choice for landscapes where berry cleanup is undesirable.
- 🌱 Holly plants are dioecious, meaning male and female flowers appear on separate plants; a single male tree can pollinate multiple female hollies in the area (up to 1/3 mile away).
- 🌱 Holly foliage contains alkaloids and other compounds that make it toxic to livestock and dangerous to ingest by humans, yet it has been used traditionally in herbal medicine under controlled conditions.
