Siberian Pea Tree Tree Seeds | Siberian Peashrub | (Caragana arborescens)
The hardest-working shrub you have never heard of.
Caragana arborescens, the Siberian Pea Shrub, is a true workhorse of the landscape. Native to Siberia and Manchuria, it thrives in extreme cold, drought, poor soils, and exposed wind where most plants fail. This nitrogen-fixing, wildlife-supporting shrub builds soil, provides food, and establishes quickly in challenging environments. For homesteaders, permaculture systems, and cold-climate growers, it is one of the most functional plants you can add to your land.
- Exceptionally cold-hardy, thriving down to zone 2
- Nitrogen-fixing roots improve surrounding soil fertility
- Produces edible, protein-rich seeds for humans and livestock
- Early yellow flowers provide critical nectar for pollinators
- Highly drought-tolerant and adaptable to poor soils
Things You Probably Didn’t Know
It actively builds better soil.
Siberian Pea Shrub forms a symbiotic relationship with nitrogen-fixing bacteria, pulling nitrogen from the air and enriching the soil around it as it grows.
The seeds are high in protein.
The pea-like seeds contain around 36% protein and have historically been used as food and livestock feed, especially in harsh climates.
It helped fight the Dust Bowl.
The USDA planted millions of Siberian Pea Shrubs during the Great Plains Shelterbelt project to reduce wind erosion and stabilize farmland.
It feeds pollinators early.
Blooming before most shrubs, it provides an early-season nectar source that supports bees and butterflies emerging from winter.

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.
