Which Tree Has Better Characteristics Sycamore Or London Plane Tree

Question From: K. krafka - Bellwood, Nebraska, United States
Q: Sycomore vs london plane tree -- Which has strongest limbs? the most drought tolerance? best longevity? Less attractive to birds? less of a seed mess? Drops leaves soonest in fall? less disease problems? Sugested web sites? cold hardy? Thanks, Ken Krafka Bellwood nebraska (eastern) Zone 5

A: Ken, Of the two I would choose a London Plane tree. However, the downside is these are considered messy trees. They drop small branches and leaves etc. Like the Sycomore, they may get anthracnose, a disease that causes leaf drop during the growing season. A couple of varieties have shown resistance, but there are no guarantees. Check out the Morton Arboretum website for more information and recommended cultivars. Best And Happy Yardening, Nancy
