Morgan "Bill" Evans (June 10, 1910 – August 16, 2002) was a horticulturalist who guided the landscape design of Disney theme parks for half a century.
He joined the Merchant Marine in 1928 and traveled around the world on the SS President Harrison, gathering seeds for his father's garden from the countries he visited.
He left school early in 1931 because of the Great Depression, and returned home to transform his father's garden into a nursery business selling rare and exotic plants to the Hollywood elite.
In less than a year, Evans had transformed 80 acres (320,000 m2) of Anaheim orange groves into lush theme park attractions filled with exotic plants.
Aside from his work at Disney, Evans was also a writer for Sunset magazine, a trustee for the Los Angeles County Arboretum, and a fellow of the American Society of Landscape Architects.
