In this episode the discussion turns toward the horticulture industry and the impact working with plants has had overtime. Bob, Greg and Sam then turn to examine the branch of Ornamental Horticulture and its culpability in the mass production and distribution of non-native plants around the world. While this trend continues, new options of planting with native plants and the idea of cultivating native plants at home for the sake of conservation are introduced.
