The Northern Catalpa (Catalpa Speciosa) is considered both a shade tree and a flowering tree. Considered a medium to fast rate grower with height increases of anywhere from 13″ to more than 24″ per year. Grows to a height of 40–60′ and a spread of 20–40′ at maturity. The Northern Catalpa can develop a unique twist in branches and the trunk. Begi3n flowering about 7 years after planting. Produces clusters of large, trumpet-shaped white flowers in May and June that are showy and somewhat fragrant. Grows in an oval shape. Features distinctively large leaves that are up to 12″ in length and 4–8″ wide, with a somewhat heart or spear shape. Yields bean-like seed pods that are 8–20″ long and ¼–½” wide, starting out green and turning brownish as they ripen. They are filled with numerous, 1″ long seeds that are fringed at the ends. Should not be planted where fruit and flowers can drop on sidewalks, as they are slippery right after they fall. The northern catalpa grows in acidic, alkaline, loamy, moist, rich, sandy, silty loam, well-drained, wet and clay soils. A wide range of moisture conditions can be tolerated, including some flooding and extremely hot, dry conditions.
Full sun and partial shade are best for this tree, meaning it prefers a minimum of four hours of direct, unfiltered sunlight each day.
