Jubaea chilensis

Probably the hardiest feather palm. This palm is from Chile , a massive palm when mature, up to 25 metre tall , with a grey trunk up to 1.3 metres wide. Large head of stiff feather leaves which are dull green above and greyish underneath. The seeds are known locally as `coquitos` or miniature coconuts where they are a delicacy.
Once covering vast areas of Chile in millions the palm was cut in huge numbers to harvest the sap from the trunks to make Chilean palm wine, each tree reportedly yielding 90 gallons. Today it is thought around 100,000 trees survive.

It is highly drought tolerant , takes severe frost when established and does not need hot summers to grow well.
Mature palms in Montpelier France survived temperatures of -17C.
Excellent gardenpalms for our climate.
