Hinoki Cypress Tree Seeds (Chamaecyparis obtusa)
Hinoki Cypress Tree Seeds (Chamaecyparis obtusa)
Sacred in Japan. Extraordinary in every garden.
Chamaecyparis obtusa, the Hinoki Cypress, is one of the most revered trees in Japanese culture, the wood of choice for Buddhist temples, Shinto shrines, and traditional wooden tubs for over 2,000 years. Its flat, fan-like foliage in deep glossy green, its warm cinnamon-red bark that peels in strips to reveal fresh red-brown beneath, and its naturally sculptural growth habit make it one of the most beautiful specimen conifers in any garden. Fragrant, slow-growing, and deeply architectural, it is a tree that improves every landscape it enters and rewards growers who appreciate patience. If you are looking to buy Hinoki Cypress seeds or grow this sacred Japanese conifer from seed, every specimen you grow from seed will be genetically unique.

Things you probably did not know about the Hinoki Cypress
It is the most expensive commercial wood in Japan.
Hinoki lumber sells for prices that can exceed ten times the cost of comparable softwoods. It is used exclusively for the most important structures in Japanese culture, including the rebuilding of the Grand Shrine of Ise, which by tradition has been demolished and rebuilt every 20 years for over 1,300 years. The shrine rebuilding ceremony requires enormous quantities of old-growth Hinoki and drives significant reforestation efforts.
The wood has natural antimicrobial properties.
Hinoki wood contains hinokitiol and other compounds that inhibit the growth of bacteria and mold, which is why it has been used for centuries for bathtubs, food preparation surfaces, and cutting boards. Modern research has confirmed the antimicrobial activity of hinoki extracts and they are now used in cosmetics and health products.
The fragrance is the subject of dedicated aromatherapy research.
The volatile compounds released by Hinoki wood, particularly alpha-pinene and borneol, have been studied in clinical settings for their effects on stress reduction, cortisol levels, and immune function. Japanese researchers have documented measurable physiological changes in people who spend time in Hinoki forests, contributing to the concept of forest bathing known as Shinrin-yoku.
Seed-grown trees develop wild variation in form.
Unlike grafted nursery cultivars, Hinoki Cypress grown from seed produces natural variation in foliage texture, branching habit, and growth rate. Some seedlings will develop compact, dense forms while others will grow more openly. This variation is what makes seed-grown specimens genuinely interesting.

FAQ
FAQ
Do you pre-stratify the seeds?
Most of our seeds are not pre-stratified. We ship them unstratified so you can control germination timing based on your local growing season. We sell to all 50 U.S. states and Canadian provinces, and since each region has different planting windows, pre-stratifying would risk seeds germinating in transit or before you're ready to plant.
True stratification requires cold, moist conditions, which can lead to premature sprouting or mold if not timed properly. To avoid this, we store most seeds in dry cold conditions to preserve viability — but this does not initiate stratification.
Do any of your seeds need to stay moist? (Recalcitrant seeds)
Yes — some species we offer are recalcitrant, meaning they must remain moist to stay viable and cannot be dried out. Examples include: Chestnut, Hazelnut, Paw Paw, etc.
These seeds are shipped in moist cold storage and are clearly labeled on the product page when applicable. Please refrigerate immediately upon arrival and follow included care instructions.
Do you ship internationally?
We currently ship to the United States and Canada only. Unfortunately, we cannot ship to other countries without a phytosanitary certificate, which is required by most international customs agencies.
If you're interested in shipping outside North America, please contact us. Note that a phytosanitary certificate typically adds $60–$80 USD per seed type and must be arranged in advance.
