Grow the world's tallest tree! Reaching heights greater than 365 feet, the magnificent Coast Redwood is not only the planet's tallest tree, but also one of the world's most long-lived, with life-spans of more than 2,000 years. Fossil records also indicate that the species is among the most ancient of trees; its lineage dating back 160 million years. At maturity, typical Coast Redwoods tower 175 to 300 feet, and have massive trunks 8 to 20 feet in diameter with deeply furrowed, reddish-brown bark. Only 5percent of America's ancient Redwoods remain, most under State and National protection. Now is a great time to plant a Coast Redwood! Gender: unisex.
