The Emerald Ash Borer (Agrilus planipennis) is a very destructive wood-boring beetle native to Asia. It was discovered in North America in July 2002, and has become established in Michigan, New York, Ohio and Ontario (Canada). Millions of ash trees have been killed in the northeastern US. Although the borer has not been detected in Florida (Dec. 2011), the presence of ash trees and the ongoing movement of wood, trees and cargo into the state make Florida an area where the beetle could potentially become established. Your help is needed to detect possible infestations so they can be quickly eradicated...if you see it, contact the Florida Division of Forestry. Use in wet settings to improve the aesthetics of drainage ponds and swales. This is a good plant to retain in natural wetlands as it is frequently used for roosting by wading birds. Often multi-trunked.

Will not produce flowers/seed unless it gets adequate winter cold, hence not recommended for use south of its native range. Salt spray tolerance was based on comments about tolerance to winter road salt in the northeastern US. Specimen tree. Woodlot tree.

Very robust.  Forms large patches.  Given its potential to be very tall, it may needs to have support from adjacent plants.   Data on salt tolerance comes mostly from northern sources where the source of salt is winter road de-icing. Background plant as tall.

While it naturally occurs in or near wetlands, this tree can also grow in uplands. Stems root readily and most of the stems stuck in a moist substrate will survive without any further care. Is often used in stream bank restoration. Plant along streams or in informal landscape settings along ponds or canals.
