Harry W. Radtke, a beloved member of the Wisconsin Green Industry Federation, died March 17 at age 74. He owned and operated W. & E. Radtke Perennial Nursery for 32 years and was always very helpful to people getting started in the industry, and that was one of the reasons he was inducted into the WGIF Hall of Fame in 2003.
Harry Radtke grew up in the family business. The family's agricultural roots go back to 1852, when Harry's ancestors grew vegetables on the outskirts of Milwaukee. The nursery relocated and expanded in 1970; eventually, the number of perennial and herb plants he grew reached more than a million every year, and his nursery became one of the largest wholesale growers in the state.
In 1998, his children took ownership of the nursery, but Harry remained part of the operation every day, as long as his health permitted.
“As long as he could, he was here every day. And we found out it took three people to replace him,” remarked his daughter Liesl. He is survived by his wife, Marilyn; his children George Radtke, Liesl Thomas and Rhonda Weber; three grandchildren, Lianne, John and Arthur; and other family members and friends who will miss him dearly.
