Chamaecyparis lawsoniana 'Silberstar' / Silberstar Lawson cypress

Chamaecyparis lawsoniana 'Silberstar' is a vigorous, columnar tree form of Lawson cypress with dense, silvery-Blue foliage. It is thought to possess exceptional hardiness and may be suitable for colder climates. After 10 years of growth a mature specimen will measure 4 feet (1.2 m) tall and 2 feet (60 cm) wide, an annual growth rate of 4 to 6 inches (10 - 15 cm).

This cultivar originated as a branch mutation on a specimen of Ch. lawsoniana 'Columnaris' found in 1955 and propagated by Hans Jürgen Höpken, Bad Zwischenahn, Germany. Plants are occasionally seen listed as, 'Hoepkin's Silberstar,' 'Höpken's Silberstar,' or simply 'Silverstar.'
