This type of work – the horticulture industry – is a big part of Mississippi’s overall agriculture revenue. Horticulture’s commodities account for some $114 million annually. Willie and Glynda Rivers became a part of the state’s horticulture arena when they moved with their four children to Rankin County from Dothan, Ala., in 1979. They soon started a small nursery business and eventually built their first greenhouse. Within seven or eight years, they had an established wholesale operation and around 16 greenhouses. A retail mart was added in 1987.
