Can you fine people help me identify some food in my garden

[Scrooge]

Right, I'm useless at this, I'm using sites like the tortoise table and I'm still frightened I'll poison Percy

We've just bought a house that has a nice weedy but nice-ish garden. Theres lots of plants front and back and here's a few I've taken shots of, are any safe to eat for Percy?

This doesn't look like normal Clover to me



Loads of these dotted around the lawn, also what about the grass itself?















I did recognise this one, safe apparently but is that the flower, the leaves or all of it?











Thanks in advance
