That is the logic I do not follow. If the plant from different habitat
that you are considering planting will support only a small number of UK

garden, in what way does planting it help make your garden more prolific
in insects and birds?

I'm so surprised you don't understand me. Hence me giving an example of
the lonely lawn and the rose bush ''garden'. This will never provide
enough habitats and will never attract enough insects. Don't you agree?
Therefore the more we plant the better. And in my other choice of
plants, vervain being European to a certain degree ...!


By all means plant it in your garden because you like it, and it adds to
your variety of plants. But if you are planting specifically to extend
your range of insects and other fauna, it makes more sense to plant
either a UK native or something closely related from N Europe.

I think we've gone full circle.
