If you don't like the phormium overhanging the path, I would dig it out. You can't prune it like that and get a good result.
It looks like Beech to me too. You can either trim it to keep it small or hedge like, or let it grow into a huge tree. If you trim in late July or August, it keeps its leaves over winter, and drops them in Spring rather than Autumn.
I think it is a Dactylorhiza fuchsii but it could be a hybrid.
Yes they look like hardy orchids, you lucky so and so. I wish they were in my garden.
I can't see a photo, is there one or is it my kindle at fault.?
A couple of metres .
Generally, they trail along the floor, a couple of metres or so.
They have tendrils ,so will cling to a support, but may also need tying on with some soft string.
2nd one is Snow In summer Latin name. Cerastium tomentosum.
No, no, no, muddle up.
Art installations do not count.
You have Norah Barlow too. Do you find it mixes with the others to get hybrids, or have you not had it long.? It's what I started with, then the bees were visiting neighbours as well, and I get all sorts.
