Growing Ilex (Holly): Blue & Winterberry Hollies

General Holly Care

Hollies (Ilex spp.) include 350+ species, known for spiny evergreen leaves and red berries. Only females produce berries; plant a male within 40 feet for pollination.

Blue Hollies (Ilex × meserveae)

Hybrids of English holly and cold-hardy Japanese species. Glossy, spiny leaves on hardier plants. Grow in full sun or light shade, average well-drained soil. In cold winters, protect from north winds. Prune late winter or after bloom (reduces fruit).

Winterberry Hollies (Ilex verticillata)

Deciduous with mid-green leaves turning yellow in fall, revealing dense red berries on females. Grow in full sun to dense shade (less fruit in shade). Prefers wet soil but tolerates average soil and drought once established. Requires acid soil. Prune late winter or after bloom (reduces fruit). Not suited for desert Southwest.
