Along with the bamboos and pampas (?) I got from my neighbours, I also have what I think is a canary date palm, in a pot , about 4Ft tall. My neighbour says it should be brought in for the winter, but a lot of websites say it is frost hardy. Does anyone have any experience of these? I haven't really got room for it in the house or greenhouse anyway & it's very spiky, so if there's no chance of it surviving outside I'll get rid of it & use the pot for something else! (I'm in Yorkshire, BTW)
If you leave it outside in a pot it probably won't survive.
As you are not worried about getting rid of it, try it in the garden (take it out of the pot). The older the plant the more likely it is to survive. Worth a try. Fleece the top in frosty weather will help as well.
