Meet Proven Winners

Meet Proven Winners

The Proven Winners cooperative is made up of an international team of horticultural experts, each of whom makes a substantial contribution to our growing program. The founding members came together in 1992 to form the Proven Winners cooperative. In partnership with one another and the network of international breeders and licensees, the founding members provide quality plant material and innovative ideas to support the continued evolution of Proven Winners. The cooperative has expanded across North America and now includes four additional licensed propagators. These operations join the founding members in producing superior Proven Winners and Proven Selections plants and marketing them throughout the United States and Canada. These unique and innovative plants are grown from materials bred by a network of top international breeders. Breeders provide plants to Proven Winners propagators located throughout the world - South Africa, Germany, Holland, Japan, Australia, New Zealand, Spain, Poland, Italy, Great Britain, Canada, and the United States.




The unique and innovative plants in the Proven Winners line are grown from material bred by a network of top international breeders.  Every plant that is chosen to become a Proven Winners has passed a lengthy series of tests lasting 2-3 years to trial the varieties for performance in numerous greenhouse and garden performance situations. This is why very few varieties are selected to become Proven Winners!
