Poplar Hawkmoth, lovely
one of the Viburnum opulus cultivars, probably 'Sterile'
Weeds re my speciality. I hold a National Collection.
That one is creeping cinquefoil, Potentilla reptans
cut the flower stems back to base but not the leaves.
Don't cut the leaves off now, plants need leaves. You can cut off the flower stems. Cut off the old leaves as new growth starts in the new year
That's the attitude
Don't get a peach or nectarine, get something unrelated that can't get the peach leaf curl
This has got a disease. I'd get rid of it. A sick plant will never be an asset to your garden
I think that's a crucifer, 4 petals, not white campion. It has the look of a gone to seed radish
But not hollyhock or foxglove either
