Our Story

We Grow Our Own Onions.
It's Not Just a Living - It’s a way of life!

Overview & Grower Profiles

Sunset Produce LLC, a family owned corporation was formed by two brothers Robert Munn and Duane Munn in 1989. Lorin Munn their father started farming near Ogden, Utah raising sugar beets and cattle along with his wife Fay and their young family. Both Robert and Duane grew up working the Utah farm with their Dad. In 1954, Lorin and Fay Munn moved their family to the Eastern Oregon/Idaho area to expand their farming enterprise. Their farm eventually grew to encompass 1820 acres including their first 20 acres of onions grown in 1965 which was a test year for this new crop. They enjoyed success growing onions and the acreage has grown each year since that time.


In 1976, the family had an opportunity to move to Eastern Washington where new land was more available to develop under irrigation. Lorin and his son Duane formed L&D Farms and at that time began developing 3200 acres of a former dryland wheat farm under center pivot irrigation. Simultaneously, Robert Munn and his family moved to the same area and bought more land to join in the development project along with some farmer friends from Idaho. Today Sunheaven Farms LLC stands as a beacon for first class large scale irrigated farming with nearly 25000 acres under cultivation. Each farmer owns their own acreage and farm as individual entities.


R. Munn Farms LLC consists of Robert and Lorna (now retired), and their three sons Randy, Ryan, and Rob. Randy has three grown sons that are now farming with their dad so the 4th generation is continuing a successful history and 2015 will be their 52nd year as onion growers. Ryan is a licensed CPA and handles all of the financial and accounting functions for R. Munn Farms. The other brothers have younger children coming up who also appear to want to follow in their dad’s footsteps as well. R. Munn Farms encompasses approximately 4500 acres with 1300 acres of onions and they grow shallots and cipollini’s to complement the onions. Other crops grown include sugar beets, carrots, turf grass seed, and cereal grains as well as some fresh peas and green beans for a regional freeze pack company. They have also been proactive in developing and implementing a bio-nematicide program with good results and continue to research natural alternatives to reduce the use of synthetic fertilizers and pesticides.


Duane Munn and Sons Farms LLC is now owned and operated by Duane and Susan Munn and Shane Munn and his family including William who wants to follow in his dad’s footsteps as well. Both families are fourth generation farmers now. Duane and Shane farm approximately 6000 acres with 2370 acres of onions for Sunset Produce. In addition to onions they also grow wheat, corn, turf grass seed, carrots and maintain a commercial cattle herd. This will also be the 52nd year of onion production for them as well.


One of the notable aspects of the success of these farms is the hands on day to day management that each family member provides. They all grew up as young people on farms and know every aspect and detail of what is required to grow the very best quality crops possible. One of the sayings while driving on the farm whenever you pass a pickup, a truck, a tractor, or a road grader you had better wave because it may well be one of the owners driving. If anyone needs to see the growers during the day we find out which field they are in and that is where we meet. 


Sunset Produce and the farms are a large company that has been built from the ground up with a solid reputation for honesty, integrity, quality, and trust. We are proud to include in our Mission Statement that we guarantee any and all of our products to our customers as well as your customers.
