Young Transplant
1 yearNewly planted 1-2 year old shrub with compact columnar form and bright blue-green foliage. Growth is slow initially.

Establishment
2-3 yearsPlant develops deeper root system and gradually increases in height and density. Foliage remains dense and compact. Growth rate of 6-12 inches per year.
Continue regular watering during dry periods. Begin light pruning in early spring to maintain columnar shape if needed. Remove any dead or diseased branches.
Mature Growth
OngoingFully established shrub reaches 3-4 feet tall (occasionally taller) with a tight, pencil-like columnar form. Foliage is dense and uniformly colored.

Flowering & Seed Production
Seasonal (spring and late summer)Tiny inconspicuous greenish flowers appear in spring; female plants produce small blue-gray berry-like cones (actually modified fleshy cones) in late summer/fall.
No special care needed. Some gardeners prune female fruits if desired for aesthetic reasons, though they add winter interest.
Winter
