Sequoia sempervirens 'Cantab' is a slow-growing, compact tree form of coast redwood with dense branching and unique, thick, fleshy needles, unlike any other in the species. Needles measure 0.5 inch (12 - 14 mm) long and 0.2 inch (4 - 5 mm) wide. After 10 years of growth, a mature specimen will measure 4.5 feet (1.5 m) tall and wide, an annual growth rate of 4 to 6 inches (10 - 15 cm).
This cultivar was selected and named in 1977 by Roy Lancaster of Cambridge University Botanic Garden, United Kingdom, describing a reverted specimen of 'Prostrata.' 'Cantab' is the name to be used for a reverted form of Sequoia sempervirens 'Prostrata.' Cantab is short for Cantabridigian, which means ‘of Cambridge.

Sequoia sempervirens 'Cantab' — a young plant yet to establish a central leader. Probably best to call this one 'Prostrata' for now.
