Common name: Ashok, False Ashok, Mast Tree
Ashok is native to India and Srilanka. Somehow, the name Ashok has stuck in north India, although the “real” Ashok is what is also called Sita Ashok.
Mast Tree is commonly seen as a lofty column, very graceful with its downward-sweeping green foliage. It is a very popular tree in India. For a short period — two or three weeks only — the tree is covered with a profusion of delicate, star-like flowers.
The tree trunks were suited for making the masts of sailing ships and hence the name.
Botanical name: Polyalthia longifolia Family: Annonaceae (sugar apple family)
