I looked it up on the RHS 

[Trillium]

I'd go for Artemisia as well, either Silver Mound, or because of its size it might be Powis Castle.

looking at the pic its not a cotton plant

[gobs]

Don't be cruel. I'm looking at real ones, not pictures. 

Dogwood then, frozen, still don't prune it.

[Aunt Sally]

Dogwood

?  Don't you mean Southernwood ?

[gobs]

There are some 500 Artemisias, I do not know them all, Aunty.

[Aunt Sally]

Isn't Dogwood a Cornus, gobs ?

[gobs]

Yeah, but I had the idea for some reason, that's where we were heading here.

Not the same as Artemesia, gobs

I bought  a lovely white daisy flower with unusual foliage - just like this - grey/silver, quite frondy and feathery - can't remember its name - just to put it into the mix!

You probably mean marguerite and it's not that either!

I still think it is artemisia.

It is an Artemis Powys castle. I have the same one. It's leaves smell gorgeous
