There is a rare redwood in Healdsburg, CA. It is the Dawn Redwood and it is the only redwood that looses its needles in the winter.

The species thrived as one of the pioneer conifers from about 80 million years ago. Metasequoia glyptostroboides is the only deciduous conifer in the world that loses its needles every winter -- and only one of three trees known as redwoods. The others are the Coast Redwood (Sequoia sempervirens) and the Giant Redwood (Sequoiadendron giganteum) of the Sierra Nevada, more familiar forest friends by far.
It was first discovered as a Mesozoic fossil in 1941, and was therefore presumed extinct – the Mesozoic ended 70 million years ago. But in 1943 a small grove was discovered in Moudao, Hubei, China, and other forest discoveries proved it still vital, though rare enough to be considered endangered. Still, from extinct to endangered sounds like a success story.

The tree was planted in the Healdsburg Square in 1953 after being gifted to the city as a potted plant. Dawn Redwoods became something of a fad after World War II, and ambitious horticulturalists planted groves of the ornamental tree worldwide.
Below is a video about the Dawn Redwood tree that was acquired by a nursery.
