There is little to indicate size here. Ar we looking at a bush, low growing perennial of something bigger?
mine's 3' wide now and hasn't started going up yet. Fairly upright isn't the same as upright.
It's a big plant. needs a good 4 foot spread, maybe more.
If it was mine I'd probably plant it.
Don't be alarmed by the rate of growth. Ferns shoot up in spring but once those fronds are uncurled that's as tall as they get.
And don't be alarmed by the bracken thing, this isn't bracken.
I'd try any garden maintenance company or tree surgeon, they have the equipment.
I think you're right, lilac, not sure which one, 'Palibin' maybe,
They're nice photos, I keep trying to get pics of some of mine but no good ones so far (pics that is, the aquilegias are lovely)
Unless you bought a named variety they won't have names. They're a promiscuous lot and every one is different.
Nut is always right, except when she's wrong
I agree with Kitty, hypericum
I don't know palms but they look more like flowers to me.
