Glauca Italian Cypress

The Story

Plant Bio

Cupressus sempervirens is a classic Mediterranean conifer known for its iconic, narrow, and fastigiate form, creating a strong vertical element in the landscape.

'Glauca' is a selected form prized for its dense, columnar habit and striking blue-green foliage that provides year-round color and texture.

Uses & Benefits:

Its formal, narrow silhouette provides a powerful vertical design element, perfect for framing entrances, lining driveways, or as a dramatic focal point. The blue-green foliage offers year-round color.

Excellent for creating tall, narrow screens in tight spaces where lateral room is limited. It can also serve as a formal hedge or windbreak when planted in a row.

While not a major wildlife plant, it provides dense cover and nesting sites for birds. Its drought tolerance makes it a good choice for water-wise landscapes.

How to Grow

Choose a location receiving at least six hours of direct sun daily.
Dig a hole two to three times wider than the root ball.
Ensure the top of the root ball is level with the surrounding soil.
Backfill with native soil, gently firming to remove air pockets.
Water thoroughly after planting to settle the soil around the roots.
Apply a 2-inch layer of mulch, keeping it away from the trunk.

Pro Tip

Ensure excellent drainage; this tree despises wet feet and is prone to root rot in heavy, waterlogged soils.

Keep It Thriving

Care Guide

Do

Provide deep, infrequent waterings once established to encourage drought tolerance.
Plant in a location with good air circulation to prevent fungal diseases.
Stake young trees for the first year if in a windy location.

Don't

Do not plant in heavy clay or poorly drained soils.
Avoid overwatering, as this is a primary cause of failure.
Do not shear the top, which can ruin its natural form.
