It is a large, Colorado native shade tree that is well adapted to our area because it tolerates drought conditions well. It is easily identifiable by it corky ridged bark as it matures. This is a great street tree that is capable of reaching 60 feet tall and 40 feet wide. Its flowers are insignificant and the fruits are small and pea sized. The nipple gall is a problem as the leaves are often disfigured by these small bullet-like growths, however this is only an aesthetic problem.
