Baldcypress

Taxodium  distichum
Although this tree is native to the Southeast, it is very hardy and adapts well to SW Ohio. This slow-growing tree can reach heights of 35-120 ft. and likes wetlands and grounds along rivers. These growth characteristics make it a good conservation tree since it absorbs much water. Its lacey, needle-like leaves turn yellow and red and drop every fall.  It grows best in full to partial sun. The heart wood is rot resistant, which is probably why it is a good source of mulch. There are several good specimens in Washington Park and the Greenbelt. The state champion is in Spring Grove Cemetery.
