Northern Catalpa, Catalpa speciosa are beautiful trees. They flower later in spring to early summer usually May or June. The flowers are very striking. They are white with purple markings.
This tree has a spread of 20 to 40 feet and a height of 40 to 60. One drawback to planting this tree is that fast growing trees tend to be weak wooded trees. The Northern Catalpa in the picture is fairly close to the house. Consider using this tree to shade the back yard or at least place it further away from the house.
But while in flower, this tree is spectacular. The leaves are heart-shaped or cordate leaves. In the fall of the year, you would have to rake the leaves so that they will not smother the turf. The size of the leaves can be from 6 to 12 inches. They are a little difficult to totally breakdown under the mower blades.
Because these trees are fast-growing, people look to these trees to provide shade. They grow in zones 4 through 8.
The best features of this tree are as follows:
- tolerates hot weather
- drought tolerant
- grows in a wide range of soils including alkaline soils
