Sequoiadendron giganteum, or sierra redwood, is a non-native tree species in Ontario that naturally grows only on the western slope of the Sierra Nevada range in California. It is a fast-growing tree suited only for very large properties due to rooting requirements. It prefers deep, well-drained acidic, loamy, wet, soils. It is generally intolerant of extreme temperatures. Sequoiadendron giganteum drops a moderate number of needles and small cones, with the heaviest shedding in the fall. It is considered moderately messy due to the needle drop and cone litter that require regular cleanup.
