Abundant and highly invasive species. Introduced into the United States from China in the 1700s, it now grows across much of the country. It is common in Maryland along roadsides and in disturbed areas. Mechanical and chemical methods of control are expensive and not very effective.
Tree of Heaven is readily recognizable in winter by the membranous, twisted fruits, or samaras.
Easily found in empty lots and along roadsides.
A primary larval host plant of the Ailanthus Webworm Moth. Tree of Heaven is also the primary host plant for the newly arrived, invasive planthopper Spotted Lanternfly. The specialized mouthparts of the lanternfly pierce the phloem tissue of leaves and stems and suck the sap; the insect does not eat the fruit or the leaves per se.
