Giant Sequoia Tree Seeds (Sequoiadendron giganteum)
Giant Sequoia Tree Seeds (Sequoiadendron giganteum)
The largest living thing on Earth. Grown from a seed smaller than an oat flake.
Sequoiadendron giganteum, the Giant Sequoia, is the largest tree by volume on the planet and one of the most awe-inspiring organisms you can grow. From a seed no larger than an oat flake rises a tree capable of living for millennia and reaching staggering size. Native to California’s Sierra Nevada, it has proven surprisingly adaptable in cultivation, thriving well beyond its original range while maintaining the same massive presence and longevity.
- Largest tree by volume on Earth
- Cold-hardy beyond its native range, thriving in zones 6–9
- Produces cones that can remain on the tree for decades
- Extremely long-lived, with some trees over 3,000 years old
- Thick, fire-resistant bark protects mature trees from damage
Things You Probably Didn’t Know
Fire helps it reproduce.
In the wild, heat from fire helps open cones and prepares the soil for seedling establishment, making fire part of its natural lifecycle.
It thrives far from California.
Giant Sequoias have been successfully grown in Europe since the 1800s, with large specimens now established across the UK and beyond.
The bark protects it for centuries.
The thick, fibrous bark resists fire and damage, allowing mature trees to survive events that would destroy most other species.
Some individuals predate recorded history.
Many Giant Sequoias were already standing when ancient civilizations were just beginning, making them among the oldest living witnesses on Earth.

FAQ
FAQ
Do you pre-stratify the seeds?
Most of our seeds are not pre-stratified. They are stored under dry, cold conditions to preserve viability without initiating stratification, allowing you to time germination for your local growing season.
The exception is recalcitrant seeds. Because these seeds must remain moist to stay viable, they are kept in moist, cold storage and are therefore in a pre-stratified state. Depending on how long a particular batch has been stored, some may arrive with an emerging radicle and be ready to plant immediately. Radicle development is not guaranteed.
Please refer to the individual product page and included growing instructions for species-specific requirements.
Do any of your seeds need to stay moist? (Recalcitrant seeds)
Yes. Some species we offer, including Chestnut, Hazelnut, and Paw Paw, are recalcitrant and must remain moist to stay viable.
Please refrigerate these seeds immediately upon arrival unless they have already developed a radicle. Seeds with an emerging radicle should be planted promptly.
Do you ship internationally?
No. We currently ship within the United States only.
We previously shipped to Canada, but tariffs, duties, and import fees resulted in customers receiving significant and unpredictable additional charges upon delivery. Because we cannot reliably calculate or absorb these costs, we have suspended shipping to Canada.
At this time, we do not ship to Canada or other international destinations.
