Whiteclintonia (Albizia kalkora)

The Tree of Heaven (Ailanthus altissima) is a medium-sized ornamental tree that shares some characteristics with the Silk tree (Albizia julibrissin). Known for its decorative appeal, Ailanthus altissima features attractive foliage and rapid growth. However, its aggressive nature and remarkable ability to self-seed have led to its invasive spread in North America, where it disrupts native ecosystems.
