Chamaerops (Dwarf fan palm)

I have recently been give one a Chamaerops but I don't know the variety. There seems to be conflicting advice on the hardiness. Its quite big, about 4ft tall. Is there any way of identifying the variety? Has anyone any experience of overwintering one of these outdoors? I am in West Essex.

 

Could well be Humilis which is the commonest

Its said to be hardy as a big mature plant, If I was you considering the winter being forecast I would give it some protection over winter, either in a greenhouse, conservatory, or a sheltered spot and protected with fleece during the coldest spells

 

I've got a humilis, been growing outside for about 5 yrs now. They come from southern Europe, and can take quite a bit of frost. The first 3 yrs I protected mine, although it is planted in a sunny sheltered area near to the house.
I have heard that minus 5 C is about the limit, after that you get some damage and with a newly planted plant, probably death.
I definately would not plant it out at this time of the year, I'd wait till spring.
Do you know if it is an import, or was it grown in the UK, it could affect hardiness.

 

It came from a friend who now has no where to put it now he has moved. He got it from a garden centre where they said it was hardy, but who knows? He had it outside under a verandah but lived in town whereas we are out in the sticks. Its in a big pot, very difficult to move, and I intend to keep it in it. Ground here is heavy clay and not at all well drained. I don't think it would like it. I have it positioned near the house in a sunny, sheltered position so I will follow your advice and give it some protection if we get a really cold spell. Thanks to you both.
