Emerald Cedar

Iseli Fastigiate Blue Spruce is perfect if you are looking for colour all year. A cultivar of the Blue Spruce, it is also known as the Columnar Colorado Blue Spruce. The Iseli Fastigiate Blue Spruce is one of the more distinctive evergreens. Its foliage is blueish in the spring and blue/green in the winter. Best used as an accent tree, the Blue Spruce has a narrowly upright and columnar form with upwards forking branches.

Emerald Cedar makes a great addition to landscapes, and is often used to form tight hedges or privacy screens. The thick scale-like foliage adds texture and colour to yards and is commonly used to line driveways. Unlike other cedars it retains its green colour throughout the fall and winter.

It is a semi dwarf species, which generally needs little pruning, but if desired it responds well to trimming. Its attractive, columnar shape and dense foliage makes it a desired landscape feature.

The Emerald Cedar won the award of merit from the Royal Horticultural Society.
