Sequoiadendron giganteum 'Powder Blue' is a robust selection of giant sequoia that, in time, will grow to massive proportions with open branching, exceptional powder-blue foliage and larger-than-typical seed cones. It grows somewhat broader and much more open than the more commonly seen Sequoiadendron giganteum 'Glaucum.' After 10 years, a specimen will measure 15 feet (4.5 m) tall and 8 feet (2.5 m) wide, an annual growth rate of 16 to 20 inches (40 - 50 cm).
This cultivar originated as tree found growing in a neighborhood in the 1990s, and selected and named by Gordy Halgren of Peacedale Nursery, Snohomish, Washington, USA. At the time of introduction, some catalogs listed it under the name 'Powdered Blue.' Over the years, this discrepancy has apparently settled out, leaving little dispute.
