If you want to grow a majestic Coastal Redwood in your landscape, join gardening expert Logan Hailey as she describes how to plant and care for the world's tallest tree!
Do you want to grow the tallest tree in the world? If you live between Central California and Southwestern Oregon, you can grow the iconic Coast Redwood tree in its native zone. Also known as California Redwood, these tremendously tall trees grow wild exclusively along the southern parts of the Pacific Northwest Coast. They rarely thrive more than 50 miles inland. However, the stately conifers can be cultivated in many locations around the world with some extra maintenance and modifications.
For example, California’s Coast Redwoods have successfully grown on plantations in New Zealand since the early 1900s. Even Hawaii has redwood forests on both Maui and Kauai, but the trees only grow successfully above 6,000 feet in this tropical zone. In colder and drier regions, the redwood cousin, Giant Sequoia—native to the Sierra Nevada Mountains—is a reliable option for a home landscape. This species can also be grown on the East Coast, but they tend to be much shorter.
Let’s dig in how to plant and care for your very own Coast Redwood. This tree easily out-lives your great grandchildren and acts like a living legacy of your love for gardening!
History and Cultivation
Crowned the tallest tree in the world, Coast Redwoods are a breathtaking sight to behold. People from all over the globe trek to Northern California to experience the last of wild old-growth redwood forests. These one-of-a-kind conifers grow up to 300 feet tall and can live to be 3,000 years old or more. Only about 5% of the original redwoods remain in the world, but you can play a role in keeping this ancient species alive by planting it in your landscape.
Fortunately, this tree doesn’t only grow in its native range. Sequoia sempervirens can be cultivated as a landscape tree in many other places. With proper moisture, temperature, and soil, the seedlings grow into magnificent ornamental specimens in a variety of climates. The species is also one of the fastest-growing trees, averaging a whopping 3 to 10 feet per year!
What is a Coast Redwood?
Coast Redwood, or California Redwood, is botanically known as Sequoia sempervirens. It is the tallest tree in the world, reaching up to 300 feet tall. One of the fastest-growing conifers, Coast Redwood is native to a limited range on the foggy Pacific Northwest coast, but it can be cultivated in other areas.
These fire-resistant, tannin-rich, ultra-resilient trees have been around since the age of the dinosaurs. They have significant ecological value, and redwood forests even create their own weather patterns!
Are Redwoods the Tallest Trees in the World?
Sequoia sempervirens, or the Coast Redwood, is the tallest recorded tree on the planet, reaching heights up to 300 feet. For comparison, the tallest pine tree is about 260 feet, and the tallest tanoak is 160 feet.
A redwood relative, the Giant Sequoia or Sequoiadendron giganteum is the largest tree in the world by volume, but they don’t grow quite as tall as Coast Redwoods. Both species can live to be thousands of years old. They are endemic to California and a small portion of Southern Oregon.
Can You Grow a Redwood in Your Garden?
It is perfectly legal to grow a redwood in your garden, but it is illegal to cut down, dig up, or propagate a wild protected tree. Instead, you must propagate redwoods from seeds or nursery stock. It is important to match the right species to your climate or make significant modifications to keep the tree alive outside of its native California range:
Coast Redwoods are very picky about their environment, requiring lots of humid or foggy air, moist but well-drained soils, and mild temperatures between 30-70°F (-1 to 21°C).
Dawn Redwoods, native to China, are more flexible and desirable for ornamental use.
Giant Sequoias are ideal for dryer, colder regions, and low-elevation mountains.
Propagation
This coniferous (cone-bearing) tree can be propagated by seed, cutting, or sucker shoots. The seeds tend to have low germination rates, so vegetative propagation is the most common. You can also find varieties of Sequoia sempervirens seedlings at ornamental tree nurseries.
If you want to get the largest tree possible in a short amount of time, purchase an established redwood from a tree nursery. Most propagation methods take one to three years to produce saplings large enough to plant in the ground.
