From what I can work out it seems very much like a "trachycarpus", common names, Chinese windmill palm, windmill palm or chusan palm.
Or a "chamaerops humilis", common names, European fan palm, Mediterranean dwarf palm.
Thing is, both are down as winter hardy in UK. Yet this spring it looked on it's last legs, though to be fair, as you can see, it's doing ok now.
I don't want the cycle to be, do ok in summer, almost die in winter, come back the following summer, almost die in winter, etc etc etc.
Or, maybe it was because I only planted it last summer that it didn't fare too well in its first winter. It might be "bedded" in a bit better now and might do ok during this winter.
I'll probably just leave it where it is and see how it looks in spring of 2022.
