As Director of Product Development for J. Frank Schmidt and Son Co., one of the world’s largest nurseries, he created an extensive tree evaluation program, testing virtually every new deciduous cultivar during his 40-year career. Partnering with scientists, breeders, and nursery growers, he guided 87 new tree cultivars to commercial introduction, including 37 trademarked or patented trees from his personal breeding and selection work.показать меньше
