Pandanus tectorius (a.k.a. “Wild Pineapple” in Chinese) can be widely seen in outlying islands and along coastlines in Hong Kong, such as Tung Ping Chau, Grass Island and Wong Chuk Kok.
It grows wild mainly in semi-natural vegetation in littoral habitats throughout the tropical and subtropical Pacific, where it can withstand drought, strong winds, and salt spray. It propagates readily from seeds.
“Wild Pineapple” can be eaten raw or cooked. The fibrous nature of the fruit also serves as a natural dental floss.
