Paradise-tree Ailanthus altissima

Phonetic Spelling

This plant is an invasive species in North Carolina
Description

Tree of Heaven is a non-native invasive small tree that has naturalized in many parts of the USSA and all areas of NC. The leaves are the best way to identify this tree as the large compound leaves have a  glandular, notched base on each leaflet. In spring large clusters of yellow flowers appear above the trees that are followed by winged fruits that are dispersed by the wind or water. They also spread suckers.

The tree forms dense, thickets that will displace native species and is tolerant of poor soil increasing its invasive abilities.  It will even grow in the cracks of pavement. It is reported to be invasive in natural areas in 30 states across the continental U.S. and Hawaii. 

Please choose native trees to plant instead.

Insects, Diseases, and Other Plant Problems:    Very invasive.
