I am gradually replacing a stretch of shrub honeysuckles and multiflora roses that back up to a deer fence. The fence is see-through and sometimes breached, so having a dense and fairly high shrub border is important. I have planted two native elderberries which are doing well, but there is a gap about 12 feet wide between them. What would you recommend to fill the gap? Another elderberry, maybe a contrasting variety? And what about fronting all of them? The elderberries jumped to about five feet in one season but are very leggy. It's hard to describe the sun exposure but it seems to be fairly moist, good drainage, and in a clearing that gets full sun about half the day. This part of the property (a hillside) was made into a maze of paths, using forsythia and spirea as well as the honeysuckle. I am keeping the basic concept but trying to move it to a more interesting and bird friendly sanctuary. It's one of those areas that needs an incentive to visit if you know what I mean. It requires climbing a hill and isn't on the way to anything in particular. There is the view from the high point, but for that there is a shortcut. In short, a knock-your-socks off mixed shrub border - native, deer-resistant - is what I'm after! Thanks.
