Excerpted from the website:
- Redwoods have grown and prospered in many areas of Europe, Asia and North America since the warm Paleozoic Era over 160 million years ago. Changes in climate have restricted their natural range and eliminated all but three genera of redwood. Dawn Redwood, (Metasequoia glyptostroboides), is native to a remote area of central China. The Giant Sequoia, (Sequoiadendron giganteum), is native to the western slope of the southern Sierra Nevada mountain range in California. The Coast Redwood, (Sequoia sempervirens), is native to the Pacific Coast from southern Oregon to central California, extending not more than 50 miles inland.
