Physical Description
Habit: Upright shrub .
Flowers: White flowers. Blooms in mid-spring. Atrracts bees and butterflies.
Seeds: Fruit: Females produce red berries in fall and autumn if a male of the same species is within 100 feet. Many migrating birds, such as robins, will gorge on the fruit.

Size/Age/Growth
Growth Rate: Slow to moderate.
Landscaping
Care: Follow a regular watering schedule during the first growing season to establish a deep, extensive root system. Feeding should be done in early spring or late autumn with a fertilizer formulated for acid-loving broad-leaved evergreens, such as cottonseed meal , rhododendron fertilizer, Miracid®, etc. If pruning becomes necessary, do it in early spring before new growth begins, trimming towards a symmetrical shape .
Biology
Growth
Culture: Space 36-48" apart. Propagate from cuttings. Plant your holly in early spring , before new growth begins and mulch with a 2- to 4-inch layer of wood chips , sawdust, pine needles , ground bark or other coarse material to keep the roots cool and moist.
Soil: Requires well-drained, slightly acid, fertile soil.
Sunlight: Sun Exposure: Sun to partial shade. Although semi-shade is preferable in midsummer, the more light it has the more dense its foliage will be.
Moisture: Water Requirements: Keep the soil moist during the summer growing season , but allow it to dry somewhat in early fall to allow the new growth to mature enough to resist winter damage.
Temperature: Cold Hardiness: 7a, 7b, 8a, 8b, 9a, 9b, 10a, 10b, 11. (map)
