Hyophorbe lagenicaulis, known commonly as the Bottle Palm or Palmiste Gargoulette, is a species of flowering plant in the Arecaceae family. It is native to Round Island, Mauritius.
Bottle Palm has a large swollen (sometimes bizarrely so) trunk. It is a myth that the trunk is a means by which the palm stores water. Bottle Palm has only four to six leaves open at any time. The flowers of the palm arise from under the crownshaft.
Bottle palms are very cold sensitive and are killed at 0°C (32°F) or colder for any appreciable length of time. They may survive a brief, light frost, but will have foliage damage
