Garry Grueber
Garry Grueber, the CEO of Cultivaris GmbH, recently announced he is retiring. Grueber’s name will be remembered for his countless ground-breaking product innovations such as Euphorbia ‘Diamond Frost’, Cleome ‘Señorita Rosalita’, Erysimum, Bacopa, and Scaevola, and plant brands such as Fall Magic® and Spring Magic®. He was also one of the founding members of the international Proven Winners network.
According to a statement from Cultivaris, “Grueber is one of the very few individuals in the plant industry that have an intuitive gift for recognizing the potential of truly innovative products and concepts with solid sales potential. Over the years, he has brought joy to many garden enthusiasts – but has also excelled in generating substantial sales and profits for growers around the globe.”
“’After many decades of intense work and a worldwide travel regimen, the time has come to slow down a bit’ as Garry Grueber explained – but also says that he is ‘very grateful and honored to be passing on a huge range of ideas and innovation potential to the next generation of plant scouts, breeders, and product managers.’”
As of January 2026, Grueber will step down as CEO of Cultivaris GmbH and subsequently withdraw from the operative part of the business. His current responsibilities will be assumed by Robert Wacker, his partner of many years at Cultivaris GmbH, who has managed finances and sales to date.
With his own consulting firm, Garry will continue to offer his services to interested plant breeders, growers, and the industry.
“I could not imagine slamming on the brakes and going from 100 to zero; I would very much like to remain active in the green industry and share my accumulated knowledge and experience in a constructive manner – albeit on a rather reduced level moving forward,” Grueber says.
Grueber says he is confident that innovative breeding and product development will continue to be of utmost value and vital importance to the next generation of plant enthusiasts and growers, even given the current uncertainties in the international marketplace.
“Even given semi-retirement, I will continue to keep an eye on the dynamic changes in the industry, but am also looking forward to having more time for my much-neglected other hobbies,” Grueber says.
