Catalpas have elegant narrow and upright canopies that mature to about 50′ x 25.’ They are slow growing trees that prefer medium soil moisture. They do well in most soil types and are drought and winter tolerant. Catalpas have very large, heart-shaped, dark green leaves. The seed pods are very large and resemble cigars which remain through the winter and give the tree its second common name of “cigar tree.” Beautiful white clusters of trumpet-shaped flowers bloom in the late spring and make catalpa trees an appealing selection for the Front Range.
Occasional structural issues that can be addressed when the tree is young with structural pruning.
Some fungus problems occur, but not generally a problem.
Eriophyid mites can be an issue sometimes, but it are fairly uncommon.
History and Use
Catalpa wood has been traditionally used outdoors for things like railroad ties and fence posts because of its natural resistance to decay. It is also used for furniture making because it is a clear and fine looking grain and is stable. Anglers will seek out catalpa trees that are infested with Catalpa Sphinx Moth to use them as bait.
