I got some great advice on here for a small tree a couple of years ago and the weeping pear we put in is doing well.
I'm now looking for a hardy shrub for a downward sloping, east-facing border between a terrace and the lawn. I have taken out a huge buddleia which had taken over and cut back a massive, straggly, old hypericum and several smaller ones. The soil is acid with clay. Ideally I'd like something that flowers and will attract butterflies and bees. Scented would be nice next to the terrace. Evergreen would be great too. Maximum height 2m when fully mature. There are already laurels, rhododendrons, hydrangeas and spireas in the garden.
