Why We Grow Pea Vine on Our Organic Farm

Originally from the Mediterranean basin and the Near East, the common pea (Pisum sativum) is one of the first crops planted each spring on our certified organic farm in Palmyra, Wisconsin. From early April through June, we carefully watch and tend to the pea vine and marvel not only at pea vine’s beauty, but also at how the plant contributes to the ecosystem of our farm.

More than just an ingredient we grow, pea vine has a number of supplementary benefits that improve the health and quality of everything else grown on our farm.

Benefits of Planting Early

When farming organically, managing insect and weed infestations is a serious concern. The pea vine’s preference for cooler climates makes it perfect for organic farming because the low temperatures keep the bad bugs at bay and prevent most weeds from taking root before the pea vine starts to come in.

Attracting & Supporting Pollinators

Pea Vine at Standard Process organic farmPea vines are an incredibly critical contributor to the balance and health of our ecosystem, and also one of the first crops on our farm to bloom. Our pea vine fields attract many colonies of beneficial insects, namely pollinators, to our farm. This arrival of pollinators is invaluable, not only for the pea vine, but also for the other acres of plants we grow here. Pea vine flowers attract ladybugs, parasitic wasps (that eat the bad bugs), bees, butterflies, and other important pollinators throughout the spring and summer.

We’ve purpose-built our farm and plan our growing season to support pollinators on our organic farm like the ones attracted to pea vine flowers. Watch this video to learn how we support pollinators throughout the growing season on our farm.


We harvest and juice the organic pea vine grown over several days during June and July. Each day of harvest typically yields several thousand gallons of pea vine juice – sometimes up to 6,000 gallons per day. We like to process the pea vines early in the morning, before the heat of the day puts the plants into a defensive mode. This early morning harvest produces some of the most beautiful juice we’ve ever seen.

Good for the Ground

Healthy soil with the right amount of nitrogen is a critical resource that must be managed carefully and effectively on an organic farm like ours. Nitrogen is a key building block for healthy plant growth. Pea vine is a legume that will create and store nitrogen in its roots to be shared at a later date. In this way, pea vine can benefit a fall crop such as Spanish black radish or leave the soil healthy for the following growing season.

Added Bonus: Next Year’s Crop

For our pea seeds, we look no further than our farm. We are fortunate enough to grow enough peas to furnish seeds for the following year’s planting season. This means we know where the seeds come from, and we can uphold the farming tradition of farmers using their own seeds rather than relying on large agribusiness that impose seed rules on farming practices. Plus, we like the idea of self-sustaining crops that allow us to rely solely on our ecosystem and farming practices to perpetuate healthy growth of crops and land management.

Historical Significance to Standard Process

In addition to the pea vine’s critical role in supporting our farm and our native pollinators, pea vine is also one of the key ingredients in our first formula, Catalyn®. Early labels from the 1930s list “green peas (whole plant)” as one of the main ingredients.
