Yes.

much more than off flowerbeds.

Birmingham bees do well from the well-established lime trees lining many of
the streets; cars parked under them do not do as well.

Blooms

But the flowering period is not long - there has to be a succession.

And I still ask - where are all the crops in a city?  Do we really need bees
there, other than to keep beekeepers amused?  If we are going to spend money
'saving the bees', is it not better spent elsewhere?
