I have been advised by a local nursery to plant dogwoods instead of alder for a wet part of my garden. I want to form a hedge /screen . What in you opinion is the best and which would look the best?
Much depends on the size of the area. If it is good sized area then plant alder to fill it, or dogwood for a smaller area. The dogwood to plant is Cornus stolonifera. which is best in wet ground.
Or plant both, some taller alder at the back and a scatter of red-twigged dogwood in front.
