Coastal Redwood Seeds (Sequoia sempervirens) | Premium Tree Seeds to Grow Your Own Giant California Redwood

🌲 Grow Your Own Coastal Redwood, the Tallest Tree on Earth

The coastal redwood (Sequoia sempervirens) is the tallest living thing on the planet, a fog-loving giant of the northern California and southern Oregon coast that can climb past 350 feet and live for thousands of years. Starting one from seed is a quietly extraordinary act: you are planting something that can outlive every person who ever walks beneath it. These premium seeds give home growers, landscapers, and restoration planters a direct way to raise their own ancient giant.

Among the fastest-growing conifers on Earth, coastal redwoods can add several feet of height a year once they settle in, with cinnamon-red fibrous bark, soft evergreen needles, and that unmistakable cathedral presence. Whether you want a single legacy tree, a sheltering grove, or a striking young specimen for a container or bonsai, this is where that hundred-year story begins.

Sequoia sempervirens is native to the cool, misty fog belt of the California and Oregon coast, and it grows best in the humid, moist conditions it evolved in. We partner with a vetted California seed farm that specializes in exactly those conditions and collects from healthy, mature groves, to the same soil-first, biological standard that defines our own Colorado farm. Every packet we ship is held to that standard and backed by the same 100% money-back guarantee as everything we carry.

🌱 A Tree for Every Kind of Grower

🌲 Starting Your Seeds

Coastal redwoods reward a start that mimics their native coast. A cold-moist stratification of 30 to 60 days in the refrigerator, followed by surface sowing in a moist, acidic, well-draining mix under bright indirect light, gives your seeds the cool, damp beginning they evolved with. Press the seeds gently onto the surface rather than burying them, since they germinate best with light, keep the medium consistently moist and humid, and shelter young seedlings from hard frost. Because redwoods reward generous sowing, we suggest starting more seeds than the number of trees you ultimately want and growing on the strongest seedlings. Our coastal redwood growing guide walks you through every step.

Building a redwood collection? Many growers pair these with our giant sequoia redwood seeds and our dawn redwood seeds to grow all three legendary redwoods side by side.

🌿 Frequently Asked Questions

Do coastal redwood seeds need cold stratification before planting?

Yes, and it is the simplest way to get the best results. We recommend a cold-moist stratification of 30 to 60 days: tuck the seeds into a little moist sand or a damp paper towel, seal them in a bag, and keep them in the refrigerator. This mimics the cool, damp winter the species evolved with along the California coast and helps your seeds germinate more evenly. An overnight soak in cool water beforehand gives them an extra head start, and our coastal redwood growing guide walks you through the full process.

Can I grow a coastal redwood outside of California?

Yes. Coastal redwoods are happiest in USDA zones 7 to 9, in the cool, moist, humid conditions of the foggy coast they come from. With consistent moisture, acidic well-draining soil, and protection from hard frost while they are young, growers well beyond California raise them beautifully. Container growing also lets you give a young redwood the sheltered, humid start it loves before you move it to its forever spot.

How many seeds should I start, and which pack size is right for me?

We offer 5, 40, and 250-seed packs so you can match the project. The 5-seed pack is lovely for a single keepsake tree or a gift, the 40-seed pack suits a home grower who wants a few strong seedlings to choose from, and the 250-seed pack is built for groves, windbreaks, and reforestation plantings. Because redwoods reward generous sowing, we suggest starting more seeds than the number of trees you ultimately want and growing on the strongest seedlings.
