Bill's Blue Deodar Cedar

Cedrus deodara 'Bill's Blue'

The Story

Plant Bio

Cedrus deodara, native to the western Himalayas, is a large evergreen conifer featuring horizontal branching with gracefully drooping branchlet tips. Its slender needles are arranged in dense spiral clusters along short shoots, accompanied by barrel-shaped cones that mature over the course of a year.

'Bill's Blue' is distinguished by its intense powder-blue foliage and a broadly pyramidal form with ascending branch tips that nod only subtly at the ends. It maintains rich glaucous blue-grey color throughout the year and exhibits a slightly more disciplined habit than the species.

Uses & Benefits:

Ornamental UsesStriking architectural profile with powder-blue foliage that persists year-round.
Practical UsesOnce established, displays high drought tolerance and low overall maintenance needs.
Ecological BenefitsProvides dense year-round shelter and nesting habitat for songbirds.

Planting

How to Grow

  1. Select a planting site in full sun to light shade with deep, well-drained soil.
  2. Dig a hole twice as wide as the root ball and equal in depth, keeping the root crown level with surrounding soil.
  3. Backfill with native soil, firm gently to eliminate air pockets, and water thoroughly.
  4. Apply a 3-inch layer of organic mulch around the base, keeping it clear of the trunk.

Pro Tip

Plant in well-drained soil and avoid cutting back into older, leafless wood, as deodar cedars cannot regenerate shoots from bare timber.
