I should think that Solanum is S. crispum 'Glasnevin'. it's one of the most common garden ones.
I wondered if the yellow might be an erigeron
I've blown them all up and can't see any ivy at all, I think it's all Russian Vine as Fritillary suggested.
This is Salvia barrelieri, not one I know but Robin's Salvias has been a reliable source of info in the past
It sounds as though you haven't got S.barrelieri but without a photo it will be difficult to ID.
odd to see it from the top like that but I think it's a Godetia
are we supposed to use tools? No wonder there's always dirt under my fingernails
top one looks like a tomato
I fear that's dead wakeshine
My money would be on voles.
unless you've got molehills,
I think Victoria is right
gardening is full of mysteries Michael
