The left and right peachy and pink flowers appear to be Diascia.
Trailing Lobelia 'Sapphire' and angel wing Begonia are below those.

In the middle with red hanging flowers, Begonia Superstars.

Thank you all so much, I really appreciate this!

Double Pelargonium at the top and what looks like a variegated Hedera helix around the wheel.

Can anyone identify the plant hanging on the front wheel?

I just said but we must have crossed in the ether - Hedera helix. The only hardy perennial planting in the barrow.

The peach coloured plant above the wheel and the pink variant above the handles are Diascia.

Thank you all, you have been a big help.
