Len Busch Roses



Len Busch Roses first opened in 1965 with a few employees, a modest 28,000 square feet of space, and a crop of pom poms. Since then, the company has grown to 530,000 square feet of greenhouses and 160 full-time workers. Len Busch Roses produces a wide variety of flowers including roses, alstroemeria, lilies, tulips, snapdragons, gerberas, and potted flowering plants. Over seven million stems and pots are produced and sold each year through its greenhouses. Len Busch Roses is one of the only rose growers in the country outside of California.

Growing roses has demanding heating requirements, especially in Minnesota’s climate, and biomass has played an integral part in heating Len Busch Roses’ greenhouses for over thirty years.
