Sequoia sempervirens ‘Winter Blue’

Coast Redwood

‘Winter Blue’ is a vigorous cultivar of the coast redwood, exhibiting a pyramidal outline and rapid growth. Within a span of ten years, it can attain dimensions of approximately 4.5 meters in height and 2 meters in width, as documented by Auders and Spicer (2012). This cultivar is characterized by its distinctive foliage coloration, which transitions from a blue-green hue in spring and summer to a much more vivid, almost shining blue during the winter months.

The origin of ‘Winter Blue’ can be traced back to its development by Dirk Winter prior to 2001. Subsequently, it was introduced into commercial cultivation by Forestfarm Nursery in Oregon, as noted by Auders and Spicer. Since its introduction, ‘Winter Blue’ has gained popularity and is now commercially available on both sides of the Atlantic Ocean.

The unique foliar color change exhibited by ‘Winter Blue’ is a notable feature that sets it apart from other cultivars of Sequoia sempervirens. While the species is known for its evergreen foliage, this cultivar adds an additional layer of visual interest with its seasonal color variation. The intense, almost shining blue hue of the foliage during the winter months is likely to be a striking sight, particularly in regions with cooler winter temperatures.

Beyond its ornamental value, the rapid growth rate of ‘Winter Blue’ suggests its potential as a specimen tree or for use in larger landscape settings. Its pyramidal form and substantial size at maturity make it a viable option for gardeners and landscapers seeking a conifer with a bold, upright presence.
