Sequoia sempervirens ?Simpson's Silver?

Sequoia sempervirens 'Simpson's Silver' is a fast growing, narrow pyramidal form of Coast redwood growing with horizontal branching with upturned tips and soft silvery-Blue foliage. Typical rate of growth in most areas is 2.5 feet (70 cm) per year, resulting is a large tree, over 20 feet (7 m) tall and 12 feet (3.5 m) wide after 10 years in the landscape.

Joseph Solomone of Saratoga Horticultural Research Foundation, San Martin, California is credited with this cultivar's introduction in the mid-1970s. Many publications list this as 'Simpson Silver.' However documents that SHRF donated to University of California at Davis clearly show the epithet in the possessive case. This is also how it is listed within the RHS conifer database. It is not known whether this cultivar has anything to do with the Simpson lumber corporation.
