A few more "what are these" photos
as promised, having been so helpful in identifying the hedging plants in our new garden, I'm now going to ask for your help with the herbaceous/border stuff. This is mostly in the "front" garden. I say "front" because the house is in one corner of a square plot so front and back are all one garden space, but this is the bit accessed from the front door, extending as far as the bridge over the pond. Thecatsfather and I also have built a gate and the start of a fence, so Daisy Doglet can be in the back garden and postie (for example) can still safely get to the front door :
But I digress
Behind me in the pic you can see the "front" garden. There's a beautiful acer, an interesting tamarisk (which you guys identified), an overgrown ilex (which may go), hostas, a couple of elders, a rose (which I found being strangled by brambles, cut everything away and found just one 6ft long rose stem striving to reach light and air, and which threw out a lovely bloom 10 days later ). Lots of hypericum, irises in the pond, a geranium, and several other herbaceousy/shrubby things which I don't know what they are. So, here you go!
1) floppy, about 2ft tall (may have been hacked back by thecatsfather so may not be showing usual flowers etc)
2) near pond, so presumably moisture-loving
3) quite big. In a prominent position so presumably a desireable plant (one pic taken mid June, second taken last week where it's started to wilt a bit)
4) about 3ft tall (2 pics)
