Wild carrot

Here's another white flower that looks like cow parsley and grows quite commonly on waste ground and by the roadside. Unlike hemlock and hemlock water dropwort (my pet hate), you could eat this one.

I've never dug one up but I suspect if you did you'd find a little orange root, which after generations of selective propagation became our edible carrot.

I've back-blipped one for yesterday as well (not even as exciting as this is).
