My garden's a real mix of wild things with the odd cultivated thing here and there. It doesn't look like a 'conventional' garden, it's haphazard and definitely not groomed. Tall hawthorn hedge currently covered in blossom, big bushy wild fuchsia in bud, lilac tree, 3 ash trees, 3 elder trees, 1 silver birch, ivy, brambles, nettles, columbine, strong mint, climbing wild rose, jasmine (I think) cotoneaster, then in a rockery I have lavender, bay, chives, parsley, rosemary and a few flowering bulbs like tulips, iris, mini daffs etc. I don't use any chemicals, so basically I grow what slugs don't eat 
I've a couple of buddleia and a bush with blue flowers waiting to be planted. It's only a good fortnight since we've stopped having night frosts, so I'll have a go and see what'll come and what won't among the seeds and bulbs I still have. I know it's late, but never say never.
I'm delighted to say we have bees in abundance, blackbirds, jackdaws, sparrows, thrush, goldfinches, chaffinches, bluetits are around every day, as are pigeon and collared doves. Jenny Wren has a quick sortie around 11am. Pheasant and red legged partridge often drop in for a wander, as does the occasional robin and a hedgehog.
Once again, thanks for such informative replies.
