Many types of palms are a good indicator of climate, and what other plants from a particular area will do well in a specific climate. Jubaea chilensis does great through out the west coast of the US (easily the most cold hardy feather palm for the west US), but on the east it rarely survives the hot summer nights. This climate matching is mirrored in the bamboo species Chusquea culeo which is from the same area of high elevation South America as Jubaea chilensis and will also not survive in the east US.
In general the plants from Madagasgar would probally do just fine in both Florida and So Cal(since the palms do), but I am excited about the So Cal match because there are so many micro climates in southern California that there is likely to be a perfect match for climate found. I think most of Madagasgar has a pronounced dry season. Coastal hills like are found around Santa Barbara, and Ventura, also have a very pronounced dry period, and the area could be a perfect match.
I would be cool if eventually some of the mainland African Ensete species were introduced into cultivation for climates like Texas, Arizona, southern New Mexico, and southern California, since some of the climates are very similar with monsoonal summer rains, and a dry die back period which is common for most of the hot climate African Ensete species.
