Giant Sequoia

Giant Sequoia is a massive evergreen conifer with a dense, pyramidal young crown, blue-green to gray-green foliage, and reddish-brown bark. In cultivation it remains a large landscape tree; wild specimens can grow far larger over centuries. ## Site and mature form The [Oregon State University landscape profile](https://landscapeplants.oregonstate.edu/plants/sequoiadendron-giganteum) describes a fast-growing tree for full sun, with deep, rich soil and adequate moisture. It notes that established trees tolerate drier conditions than coast redwoods. The [USDA Forest Service review](https://research.fs.usda.gov/feis/species-reviews/seqgig) describes its Sierra Nevada ecology and preference for deep, well-drained soils. Give it substantial space and avoid sites where mature roots or canopy will conflict with structures. Growth and ultimate size depend on age and conditions. ## Landscape use Its scale and long-lived form make it a specimen for large gardens, parks, and arboreta. It is best placed where its canopy can develop without crowding buildings or neighboring trees. ## Maintenance Water during establishment and prolonged dry spells, protect the root zone from compaction, and allow room for the mature canopy.
