3 plants need identifying please

I saw these whilst walking around Goodnestone Park Gardens and Mount Ephraim (both in Kent) and would love to get them!

 

The 3rd picture looks like one of the Artemesias, google them and see if the images look similar, but i'm not familiar with the other two.

 

1. Might be veronicastrum virginicum. Whatever it is, i've got one and it looks exactly like your one. Haven't seen/found the label for years though.

Buy culver's root Veronicastrum virginicum 'Fascination': Delivery by Crocus.co.uk

2.Might be a polygonum. Does it have pink or redd bottlebrush shaped flowers?
3.I'd go with artemisia. Does it have strongly aromatic foliage?

 

Thanks. Yes - the last one does look like a wider leaved variety of
Artemisia ludoviciana.

 

Thanks. I haven't seen any flowers, as I haven't returned to the garden since I saw it a couple of weeks ago. I'll have to go back to Goodnestone Park and ask them if they have a name for that last plant - I would have asked today whilst I was there but I had a very grumpy six year old with me!
