Paws, I was daft and forgot to add there is already a low hedge at front - it looks to be a not very exciting coniferous hedge so although I'd love something gorgeous like holly (some lovely berries out in the hedgerows and woods right now) it's already there, and of course will remain green over the winter which is a bonus. I'm planning to allow that to grow to six foot so it will block out the road from the kitchen. But I also want to grow a visual 'green screen' as to block the road from the bedroom window too. I'd prefer a native tree so my Dad suggested an Elder that's got points for having folk-lore interest and being wild-life friendly. Plus being pretty and even practical too). Though I've also considered Almond and Mulberry, don't know much about them though.

I'm in Essex, anyone relatively local who could share interesting seeds, cuttings or root divisions would be greatly appreciated! (eg: Woodland Plants, Wild Flowers, Heritage Veg., Cottage Garden Flowers and all kinds of Herbs)
