Our History

After World War II, many Dutch citizens left their native country in search of opportunities. Twenty-three-year-old Ted van der Zalm was one of them. Ted joined his brother John in Canada, eventually purchasing a rundown flower shop in St. Catharines, Ontario in 1957. At the time of purchase, Colonial Flower Shop was netting a whopping $5 per week, which would translate to fifty bucks today.

Other family members soon joined them in Canada, including brothers Jim, Clemens, and Arnold and their mother. Together, the van der Zalm family worked hard to make ends meet, taking on extra jobs until the flower business began to flourish. As the business grew, Colonial Flower Shop expanded its operations, supplying finished flowers to retail chains and rooted cuttings to growers. Today, Colonial is a leading supplier of high-quality plant materials.

Over the years, there have been many changes such as automatic watering and misting, computer controls, shade systems, rolling shipping carts, hot water heating and a biomass boiler. However, one thing hasn’t changed… Our unwavering commitment to quality and customer satisfaction.
