Osage Gardens

Style A

Osage Gardens started with a plea for land. Wanted: south-facing farmland with access to natural gas and good irrigation.

While those may not be the exact words they used in 1992, Tom and Sarah Rumery, organic farmers from Boulder, found their dream property between Silt and New Castle—twenty acres of prime agricultural land located between the Colorado River and Interstate 70 in the wide expanse of the eastern end of Colorado’s Grand Valley.

For the first decade, they focused exclusively on tomatoes. As Osage Gardens expanded, so too did a regional demand for culinary herbs so they shifted their business model to focus on basil. Their first row of basil was so successful that they expanded immediately, covering three of their 20 acres with greenhouses jam-packed with basil and other culinary herbs. 

At the same time, their significant customer base exploded to include small regional natural grocers and Whole Foods stores in the greater Rocky Mountain region, including the states of Colorado, Idaho, Kansas, New Mexico, Nebraska, Kansas, Wyoming, Utah, and parts of Texas.

Knapp Ranch purchased Osage Gardens from the Rumerys in 2019, with the intent to continue the high quality, certified organic production standards and community-based agriculture. It’s a match that makes sense given the Ranch’s dedication and commitment to sustainable organic farming and Colorado’s agricultural heritage.

Manager Jared McDermott continues to oversee day-to-day operations, ensuring that  the quality standards established by the Rumerys are continued under the Knapp Ranch ownership. “Osage Gardens is a year-round operation,” says McDermott. “The farm is busiest during November and December, but this is a business where there is always something to do.”

The collaborative partnership between Knapp Ranch and Osage Gardens is built upon a shared belief in growing fresh, healthy, and organic produce in a sustainable setting. Biodiversity, pollination, wildlife conservation, healthy soils, and clean water —everything that you would expect in an ecologically resilient landscape — are values we believe in.
Our customers are our biggest advocates and they want to know where their food comes from. Fortunately, we can tell them.
We know everything about our produce, including where the seeds came from, when they were planted, how they were fertilized, when they were harvested, and how they were packaged. We even know the composition of the soil they grow in!  With over 30 years of dirt under our fingernails, we know what our customers want. Our knack for producing quality culinary herbs in a hands-on growing environment is evident in the thousands of pounds of produce we distribute throughout the intermountain West on a weekly basis.

What We Grow

Since 1992, Osage Gardens has been growing over twenty varieties of certified organic culinary herbs including their signature Basil. Osage Gardens Herbs are available in select natural grocers and at Whole Foods stores across the Rocky Mountains, including Colorado, Idaho, Kansas, New Mexico, Nebraska, Kansas, Wyoming, Utah, and parts of Texas.

We pride ourselves on our products, which we grow using resilient and regenerative farming practices. Our highly integrated methods of composting and crop rotation enrich the naturally rich and fertile soils of the Colorado River floodplain on which our farm is located. Our methods are dynamic and self-renewing which means we don’t need chemical fertilizers, pesticides, or other artificial inputs.
