Black Locust Tree Seeds | False Acacia | (Robinia pseudoacacia)
Tough as iron. Fragrant as honey. Useful as anything you can grow.
Robinia pseudoacacia, the Black Locust, is one of the most practical and ecologically valuable trees in North America. Fast-growing and nitrogen-fixing, it thrives in poor soils while improving them over time. In late spring, it produces cascading clusters of intensely fragrant white flowers that fill the air with a vanilla-honey scent and support pollinators in force. Its wood is among the hardest and most rot-resistant available, making it as functional as it is beautiful.
- Exceptionally hard, rot-resistant hardwood ideal for outdoor use
- Nitrogen-fixing roots improve soil fertility
- Highly fragrant white flowers that attract pollinators
- Produces one of the highest-BTU firewoods in North America
- Thrives in poor, eroded, or disturbed soils
Things You Probably Didn’t Know
Stronger than you expect.
Black Locust wood is harder than white oak and more rot-resistant than cedar. Untreated fence posts have been known to last 50 to 100 years in the ground.
It produces premium honey.
Known as acacia honey in Europe, Black Locust honey is light, slow to crystallize, and highly valued for its delicate flavor.
It helped build early American ships.
Black Locust was used in shipbuilding for its strength and durability, including in the construction of the USS Constitution.
It rebuilds degraded land.
Planted on mined and damaged soils, Black Locust improves fertility and stabilizes land, making it a key species in restoration efforts.

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.
