History of Phillips Mushroom Farms
The Phillips family began growing mushrooms in 1927 on the property still used today, and Produce News reports the company is now run by fourth-generation owners. Kennett Square calls itself the mushroom capital of the world, and Pennsylvania accounts for most US mushroom sales volume.
In 2021 a new growing facility in Pennsylvania was under construction, similar to the company's existing operation in Warwick, Maryland, and the trade press has covered the company's expansion in production, advancements and staff.
What Phillips Mushroom Farms Grows and Raises
The company ships fresh mushrooms around the country and emphasizes specialty varieties such as shiitake and oyster. Organic is a growing share of sales, and the company offers a 3.5-ounce organic oyster mushroom to retail partners.
It is also testing value-added products: mushroom jerky and mushroom chips are beginning to gain traction, according to director of business development Sean Steller. Customers include retail partners and vegan restaurants that use mushrooms in meat-replacement dishes. Baldor Specialty Foods lists it as one of its primary fresh suppliers.
How Phillips Mushroom Farms Makes Money
Fresh specialty mushrooms
Fresh mushrooms shipped nationwide are the core product, with the volume of growing space giving the company scale advantages in a business that depends on steady supply.
Organic
Organic mushrooms are a growing share of sales. USDA ERS reports Pennsylvania had 61 percent of US organic mushroom production area in 2021.
Snacks and foodservice
Mushroom jerky, chips and sliced products and sales to vegan restaurants add value beyond the fresh case.
Farm Insight: What Other Operators Can Learn from Phillips Mushroom Farms
The first lesson is to lead in a niche. Specialty and organic mushrooms carry different margins than the standard white button crop, and the company positioned itself there.
The second is to add value-added products to a perishable base. The third is to scale carefully with a second facility in another state, which spreads risk while keeping the team's growing knowledge.
A farm that grows in the dark has a certain mystique, and Phillips Mushroom Farms has been doing it since 1927 without a single complaint about the lighting.
