Maclura pomifera, or osage orange, is native to regions near Ontario. This species is highly adaptable, tolerating urban pollution, a wide range of pH levels, heat, drought, and various soil types. This species is typically not recommended for planting due to its large, rough, inedible fruit that creates significant litter, along with its sharp thorns. This species can form a dense, thorny barrier and suckers freely, forming potential colonies of plants. Although this is a deterring factor, the thornless and fruitless cultivar White Shield 'White Shield' osage orange is a great choice for urban landscapes. This species is highly adaptable, tolerating urban pollution, a wide range of pH levels, heat, drought, and various soil types. Another cultivar includes Wichita 'wichita', which is a mostly thornless variety.
