Polyalthia longifolia (False Ashoka) is a lofty evergreen tree, native to India, 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.
Polyalthea 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 (Saraca indica) because of the close resemblance of both trees.
One might mistake it as a tree with effectively no branches, but in fact a Polyalthia allowed to grow naturally (without trimming the branches out for decorative reasons) grows into a normal large tree with plenty of shade.
Polyalthia longifolia's common names include False Ashoka, the Buddha Tree, Indian mast tree, and Indian Fir tree. Its names in other languages include Ashoka in Sanskrit, Unboi (উনবৈ) or Debadaru (দেৱদাৰু) in Assamese, Debdaru in Bengali and Hindi, Asopalav (Gujarati), Glodogan tiang (Indonesian), Ashok in Marathi and Nettilinkam நெட்டிலிங்கம் in Tamil, and araNamaram: അരണമരം (Malayalam). The False Ashoka was cultivated and gained popularity in British India for nostalgic reasons because it resembled the Mediterranean Cypress, and also in order to be used to make ship masts. It does not require pruning in order to maintain its tall, straight, main trunk with short, drooping branches.
Found natively in India and Sri Lanka. It is introduced in gardens in many tropical countries around the world. It is, for example, widely used in parts of Jakarta in Indonesia.
Fresh leaves are a coppery brown color and are soft and delicate to touch, as the leaves grow older the color becomes a light green and finally a dark green. The leaves are shaped like a lance and have wavy edges. The leaves are larval food plant of the Tailed Jay and the Kite Swallowtail butterflies.
