Coastal Redwood (sequoia sempervirens) seeds and growing kit in a handy mailable container. The habitat near to the Californian coast is often one shrouded in fog and it is in this moisture-laden environment that the coast redwood flourishes. The 50-60 degree average temperature of the area are also important to the life cycle of these trees. They will grow about anywhere, as evidenced by photos people have sent us over the years of trees growing in such disparate places as Fresno California, Waycross Georgia, Florida and even one hardy voyager in Phoenix Arizona. But they will never attain their true size and stature without the Coastal fogs and temperatures that nurture them.
