Chamaecyparis lawsoniana 'Westermannii' / Westermann's Lawson cypress

Chamaecyparis lawsoniana 'Westermannii' is a tall, broadly conical tree form of Lawson cypress with spreading branches and broad lush sprays of attractive, semi-pendulous yellow-green foliage that clothes to tree to the ground. After 10 years of growth a mature specimen will measure 10 to 15 feet (3 - 5 m) tall and nearly as wide, an annual growth rate of 12 to 18 inches (30 - 45 cm).

This cultivar originated as a seedling selected around 1880 by Jacques Jurissen & Son Nursery, Naarden, The Netherlands.
