Could anyone pls help with plant identification?
Visited a friend's garden at the weekend and they had a few plants they and I couldn't identify so I offered to help through this forum. Here's hoping!
Plant 1 (they don't know where this came from):
Plant 2 (some kind of iris?):
Plant 3 (some kind of giant trefoil weed to be pulled out?):
Plant 4 (afraid photo close-up not very good, should it be pruned, whatever it is?):
Many thanks for any help on these!
