Description
The Bottle Palm's stem swells from near its base

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 palms have only four to six leaves open at any time. The leaves of young palms have a red or orange tint, but a deep green is assumed at maturity. The flowers of the palm arise from under the crownshaft.

This species is often confused with its relative, the Spindle Palm, which also has a swollen trunk. However the Spindle palm's trunk swells in the middle (resembling the shape of a spindle), whereas the trunk of the Bottle palm swells from near the base and tapers further up. Its inflorescence branches in 4 orders, and its 2.5 cm fruits can be orange or black. The trunk of both species becomes more and more slender as the palm ages.

Within Mauritius, the only other extant Hyophorbe species is the common Hyophorbe vaughanii. The Bottle palm can be distinguished from this species however, by its swollen trunk when young; by its much smaller (2.5 cm) orange or black fruits; and by its inflorescence, which branches in four orders rather than three.[2]

Distribution and habitat

The bottle palm is naturally endemic to Round Island, off the coast of Mauritius. While habitat destruction may destroy the last remaining palms in the wild, the survival of the species is assured due to its ubiquitous planting throughout the tropics and subtropics as a specimen plant. It is one of three Hyophorbe species which naturally occur in Mauritius, and one of only two that are still extant.

Cultivation

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. Only southern Florida and Hawaii provide safe locations in the USA to grow Bottle Palm, although mature flowering specimens may be occasionally be seen in favored microclimates around Cape Canaveral and Tampa-St. Petersburg-Clearwater in coastal central Florida. It makes a fine container-grown palm in other locations as long as it is protected from the cold and not overwatered.

gollark: It depends what you mean by "freedom of speech", really, it's a loosely defined term.
gollark: Yes, might.
gollark: Preemptively harming people who might harm you if they were in a different position is very problematic.
gollark: I mean, I'd agree with that assessment, I just wouldn't agree with attacking them because of it.
