Bonin Islands Palm

Bonin Islands palm is a tall palm endemic to Japan’s Ogasawara (Bonin) Islands. Tokyo’s Hachijo Botanical Park reports that it exceeds 10 meters in height and identifies the island group as its native range. ## Form and origin The [Tokyo Park Association plant profile](https://www.tokyo-park.or.jp/park/hachijo/flora/detail/073.html) identifies the species as Clinostigma savoryanum in the palm family and records it as an Ogasawara endemic. Its account also notes that the young palm heart was harvested during wartime, contributing to a sharp decline in wild numbers. ## Siting Allow space for a tall palm and its mature crown. The botanical profile documents native range and stature but does not provide a verified USDA hardiness range or detailed landscape irrigation schedule. ## Maintenance Do not remove the growing tip. Avoid collecting from natural populations, since harvesting the young heart damaged wild numbers.
