Caddo Sugar Maples


Sugar maples often have significant problems with our Kansas weather. Our hot, often dry summers and windy conditions can shorten the life of these trees. However, some sugar maples are better adapted to Kansas conditions than others. Our John C. Pair Horticulture Center has evaluated sugar maples for well over 20 years and has identified selections that are much better adapted to Kansas. Of particular interest are the Caddo sugar maples which originated from an isolated population in Caddo, County, Oklahoma. These are true sugar maples and are considered an ectotype and are more drought tolerant, better adapted to high pH soils and more resistant to leaf scorch and tatter than the norm. Just how resistant to scorch is impressive. The last three weeks of August in 2003 saw temperatures at our research station over 100 degrees each day with no rain for the month prior. All other sugar maples in the trial had severely scorched leaves. Not a single leaf of any of the Caddo maples was scorched. Leaf water potential readings taken pre-dawn showed all other trees in the trial past the wilting point while the Caddo maples were barely stressed.

Another interesting characteristic of Caddo maples is that they tend to retain their leaves in the winter and therefore have been suggested as screens or for use in windbreaks. Dr. John Pair, the late director of the Horticulture Center, selected and released two Caddo maples over 10 years ago. Both these selections color early and have consistent good red fall color. Drought tolerance and resistance to leaf scorch and leaf tatter are exceptional. However, neither will do well in a heavy clay soil that is frequently saturated. These trees can be damaged or killed if planted in wet sites.

The first selection, ‘Autumn Splendor’, has the traditional sugar maple growth pattern and needs plenty of room to mature. ‘John Pair’ is smaller and more compact and more likely to fit a residential landscape. This tree is also noted for a dense, uniform crown.  Flashfire is a third Caddo maple that has done well in Kansas.  If you are in the market for a sugar maple, consider these before making a final decision.
