Catalpa speciosa or Northern catalpa is native to the Midwestern United States, ranging from southern Illinois and Indiana to western Tennessee and northern Arkansas. Although non-native to Ontario, it has naturalized here. It is a fast-growing, potentially aggressive ornamental tree that adapts well to diverse soil conditions, from dry, rocky terrain to mildly swampy areas. Reaching up to 50 feet, it provides excellent shade, making it ideal for large landscapes and parks. Its stunning flowers bloom in late spring and summer, and it attracts pollinators like bees, wasps, and flies. Though it has brittle wood and produces significant litter from flowers, leaves, and long seed pods, its beauty and shade make it a great addition to any landscape.
