rose apple; Malabar plum
Refers to the tree Syzygium jambos and its fruit. Botanical term; in everyday contexts, the fruit is not widely known in Japan.
フトモモは東南アジア原産の果樹です。
The rose apple is a fruit tree native to Southeast Asia.
植物園でフトモモの花を見ました。
I saw rose apple flowers at the botanical garden.
The Japanese name フトモモ is likely a phonetic adaptation, but the exact derivation is uncertain. The kanji 蒲桃 are ateji (当て字) borrowed from Chinese, where they originally referred to a different plant.
