Outstanding Qualities

Giant redwood is one of the most majestic of North American trees. It is not for the small garden but for large gardens, landscape and park settings due to its eventual mammoth scale. Sequoiadendron giganteum 'Glaucum' is a blue-needled selection that is ghostly and very effective as a focal point due to the lighter color. Looking out across the city and suburban landscape two trees are discernable at great distances for they puncture the canopy of all other trees and they are Lombardy poplars and Giant redwoods. Though fast growing they are best when planted fifty to eighty years previous to you when their impressive scale is imposing itself on the landscape. The blue green of the 'Glaucum' form contrast well with the dark green of the native conifers, which are predominantly Western cedar and Douglas fir. It is not a tree for the small garden.

Culture Notes
This enormous tree needs a large area to reach its fullest potential. It is quite adaptable and grows in full sun to light or open shade. Avoid planting it near buildings or pavement to limit damage from the massive roots that develop as it matures. It prefers a well-drained or sandy soil, but will tolerate clay. Once established it is drought tolerant. Little pruning is needed. Consult a professional for any tree work.
