Siberian Pea Tree Tree Seeds | Siberian Peashrub | (Caragana arborescens)
Cold-proof nitrogen fixer, golden blooms, and survival-grade toughness.
Caragana arborescens, commonly known as the Siberian Pea Tree or Siberian Peashrub, is an exceptionally hardy deciduous shrub or small tree valued for its resilience, soil-improving abilities, and usefulness in harsh climates. Native to Siberia and Central Asia, it produces bright yellow pea-like flowers in spring followed by seed pods that provide food for wildlife and livestock.
This rugged plant thrives where others fail, tolerating extreme cold, drought, wind, and poor soils. Its nitrogen-fixing roots enrich the soil, making it a powerhouse species for permaculture systems, shelterbelts, and land restoration projects.

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.
