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. Shade tree.

Can be distinguished from non-native agave by its bare basal trunk. Endemic to southern peninsular Florida from the Monroe County Keys north along the coasts to Martin and Manatee counties. Specimen plant. Plant where its pointy foliage will be an asset but not be touched.
