Chamaecyparis lawsoniana 'Wissel's Saguaro' / Wissel's Saguaro Lawson cypress

Chamaecyparis lawsoniana 'Wissel's Saguaro' is a moderately fast growing, narrow upright selection of Lawson cypress with fastigiate branching that can twist and produce arms that resemble the Saguaro cactus. Foliage is thick, contorted and blue-green in color. After 10 years of growth, a mature specimen will measure 6 feet (2 m) tall and 2 feet (60 cm) wide, an annual growth rate of 6 to 8 inches (15 - 20 cm).

This cultivar originated as a witch's broom found in the early 1960s on a specimen of C. Lawsoniana 'Wisselii' by J.B.A. Dekker, of Mijdrecht The Netherlands. A short time later, K.A. Koemans Nursery of Boskoop introduced it to the nursery trade.
