K & A Greenhouse has been a cornerstone of the Madison gardening community since 1986.

Current owners Chris and Angie, both former summer staff members with teaching backgrounds, purchased the business in 2005 and have continued its tradition of quality and service. Our team of expert growers and nursery staff specialize in cultivating locally-grown plants with minimal environmental impact, ensuring healthy specimens that thrive in Wisconsin gardens.We maintain strict quality control through on-site growing, reducing plant stress and chemical use while supporting local ecosystems.
