Sequoia sempervirens ‘Henderson Blue’

Coast Redwood

‘Henderson Blue’ is a cultivar of Sequoia sempervirens that was introduced by the Saratoga Horticultural Research Foundation in California in or before 1975. It is characterized by its upright growth habit and striking blue foliage, which sets it apart from the typical green color of the species.

The blue foliage of ‘Henderson Blue’ is its most distinctive feature, providing a unique and attractive ornamental quality in the landscape. The intensity of the blue coloration may vary depending on growing conditions and the age of the foliage, but it remains a significant aesthetic attribute of this cultivar.

In terms of growth habit, ‘Henderson Blue’ develops as an upright tree with moderate vigor (Dirr 2009). However, Jacobson (1996) suggests that it may be better suited to being maintained as a shrub through regular and heavy pruning. This recommendation is based on the observation that ‘Henderson Blue’ can develop an ungainly or less attractive habit when allowed to grow freely as a tree.

By pruning ‘Henderson Blue’ regularly and keeping it in a shrub-like form, gardeners can control its size and shape while still enjoying the attractive blue foliage. This management approach may be particularly useful in smaller gardens or in situations where a more compact and tidy appearance is desired.
