Polyalthia longifolia

Polyalthia longifolia, the false ashoka native to India, is a lofty evergreen tree, commonly planted due to its effectiveness in alleviating noise pollution. It exhibits symmetrical pyramidal growth with willowy weeping pendulous branches and long narrow lanceolate leaves with undulate margins. The tree is known to grow over 30 ft in height.

Polyalthia is derived from a combination of Greek words meaning ‘many cures’ with reference to the medicinal properties of the tree while Longifolia, in Latin, refers to the length of its leaves.Polyalthia longifolia is sometimes incorrectly identified as the ashoka tree because of the close resemblance of both trees.
