Sequoia sempervirens'Prostrata' is a low, spreading form of coast redwood with distinct, thick, fleshy, blue-green needles. After 10 years, a mature specimen will measure 2 feet (60 cm) tall and 4.5 feet (1.5 wide), an annual growth rate of 4 to inches (10 - 15 cm), significantly more outward then upward. Be aware that if a plants develops a central leader, and assumes an upright form, it's cultivar name must be changed to 'Cantab.'
This cultivar originated as a branch mutation (witch's broom) found around 1927 on the lower branches of a specimen in cultivation at Cambridge University Botanic Garden, United Kingdom. F G Preston, former superintendent of the garden is credited with the discovery.
Sequoia sempervirens 'Prostrata' — a relatively young plant in a nursery display garden in Oregon. Although labeled as 'Cantab,' this specimen has not yet developed a central leader, so it's best to identify it as 'Prostrata' for now.
