About Sobkowich Greenhouses

At Sobkowich Greenhouses we are proud of our beginnings and where we have grown to today. With over 50 years of growing experience in the Niagara Region, we're the leading choice for high-quality Proven Winners® plants in Eastern Canada.

Family-Owned For 50 Years

Sobkowich Greenhouses is a family-run operation started by Ed Sobkowich Senior and his wife Estelle Sobkowich in 1964. Ed Sr was a fruit farmer looking to continue the growing season through the winter. They decided to grow hothouse tomatoes and the first 3 greenhouses were built on their Grimsby property.

Around 1972 the business evolved into bedding plants and is now a complete floriculture production farm.

Sobkowich Greenhouses has expanded to over 160,00 square feet under cover and our first 3 greenhouses are still part of our production space today.
