Emerald Colonnade® Holly

Emerald Colonnade Holly typically grows 10–12 feet tall and about 4–8 feet wide. It has a naturally narrow, columnar shape, making it ideal for tight spaces, privacy screens, or vertical accents.

Emerald Colonnade Holly is a moderate grower, typically adding about 6 to 12 inches per year under ideal conditions.

Plant Emerald Colonnade Holly in a location that receives full sun to partial shade with well-draining soil. It performs best with at least 4–6 hours of direct sunlight daily and protection from harsh, drying winds.

For a privacy screen or hedge, plant Emerald Colonnade Holly about 4–5 feet apart to allow them to grow together into a dense, uniform screen. For more space between plants, 6–8 feet apart works well.

Emerald Colonnade Holly thrives in USDA Zones 6–9. It does best in moderate climates with well-draining soil and can tolerate both heat and humidity once established.

Prune Emerald Colonnade Holly in late winter or early spring before new growth begins. Light trimming throughout the growing season can help maintain its narrow shape. Remove any dead or damaged branches and avoid heavy pruning, as it naturally maintains a tidy, upright form.

No. The Emerald Colonnade Holly is exclusively a male holly, which means it does not produce berries. Male hollies provide pollen that helps nearby female holly varieties produce berries, but they will not develop berries themselves.

Emerald Colonnade Holly is cold hardy down to about -10°F once established. It can handle typical winter conditions within its growing zones but may benefit from protection during extreme cold snaps, especially when newly planted.

Browning leaves are most commonly caused by environmental stress, such as inconsistent watering, poor drainage, winter burn, or transplant shock. It can also happen if the plant was installed too deep. Be careful not to underplant your holly—always keep the top of the root ball slightly above or level with the surrounding soil to prevent suffocation and moisture issues.

Plant Emerald Colonnade Holly at least 2–3 feet away from a house or structure. This allows room for mature growth, proper air circulation, and easy maintenance while preventing crowding against walls or foundations. When planting, be careful not to underplant—position the root ball at or slightly above soil level to ensure proper drainage and healthy root development.

All California orders require a mandatory inspection by the Texas Department of Agriculture (yep, it’s a USDA thing!). These inspections happen about once a week—typically on Tuesdays, though the day can vary. If you place an order just after an inspection, your plant may not ship for several days until the next one. Unfortunately, we’re not able to expedite this part of the process.

Also, due to USDA regulations, we’re unable to ship oak trees, citrus or fruit trees (except olive trees) to California. This rule helps prevent the spread of pests and diseases and applies to nurseries across the country.

Thanks for your patience—we’ll make sure it’s worth the wait.
