The A. engleri is native to islands south of Japan, including Taiwan and the Ryukyu Islands. This palm can cause severe allergic reactions so best to consider wearing gloves when handling seed or fruit.
Very easy to propagate from seed. Seed bank can be viable up to two years. Propagation can also be achieved by division as well as by removing the suckers.
The plant is viable in sub tropical as well as temperate (reports it is hardy to Zone 7) climates which is most probably why it is popular for those attempting to achieve a "tropical" look in their landscape.

This is one of the best palms you can grow in San Francisco, they grow slowly but beautifully in cool coastal climates, although they would like the hotter sumers. They handle downn to 24 F, but occasionally down to 18, as one did in Seattle, but it rotted in the summer.

This is the most commonly grown palm of this genus in the US. It is a clumping palm that does very well in many of the southern states in the warmers areas (like here in So Cal). It can handle frosts down to about 24F... maybe even a bit colder. It is very drought, wind, sun and shade tolerant when mature. In the sun it tends to stay more compact and shrubby, but in shady conditions it develops longer, lankier trunks and becomes an elegant palm. It is a slow poke, though, at least when young.
As noted, it is a monocarpic palm, but since it is a suckering palm, only the flowering stem dies. It has one of the best odors of all flowers in the palm world, and very potent. It also has nice looking flowers (often an insignificant part of a palm). In Southern California it is a prolific seed producer, and seeds are generally pretty easy to germinate. Native to Japan and Taiwan
