Jubaea chilensis:

Jubaea chilensis, also called Chilean Wine Palm, is a truly massive palm in maturity (25-30 m)
and is probably the most cold tolerant of all feather leaf palms.
A plant with 1 m trunk is already 30-40 years old, for this reason Jubaea are so expensive.
This species is native to central Chile.
It is highly drought tolerant but will also do well in cold and humid conditions therefore it is well suited for most of the European climates.
Jubaea is also quite wind tolerant and also is not effected by salt air.
It does not need hot summers to grow well, and in winter it can take severe frost down to -15°C but we advice some protection by those temperatures.
For sure very small specimens should be protected for their first few winters when temperatures drop below -8°C.
