Redwood is the only naturally occurring hexaploid conifer. It is one of only a few vegetatively reproducing conifers (from stump sprouts) and possibly the tallest tree species known. Winter buds, though small, are evident.

Redwood, including Sequoia sempervirens and Sequoiadendron giganteum , is the state tree of California.
