Sequoiadendron giganteum 'Powder Blue' / Powder Blue giant sequoia

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.

Is it possible to buy some ‘Powder Blue’ giant sequoia seeds??
I have 3 species, and one 'Glaucum' but I would love a 'Powder Blue'.
Thank You,

hello Angela ... there are a couple of issues with this message.

1. Seedlings from cultivars don't necessarily come true. You will get just as many green as blue seedlings and it's not proper to call any of them 'Powder Blue'. In order to get a true 'Powder Blue', asexual propagation is required.

2. Unless somebody has donated seed and it appears on our seed exchange (in 2020 it does not), then we can't sell it to you. Plus, seed exchange is an ACS member benefit. Non members can't take part unless they join.
