Can anyone recommend a low growing, tough shrub that still looks pretty that I can plant along the front of my border to protect the plants behind it from footballs and rampaging children? I've tried growing a lavender hedge for the past few years but my soil is too damp (we're near a river and have very high groundwater) - even the English varieties don't survive a wet winter. I'm not a big fan of formal planting so want to avoid a box / euonymus hedge effect, but can't think of anything else that's evergreen! Or at least ever- present - perennials that die back underground are no use half the year or I'd go for sprawling mounds of hardy geraniums.
It's south and west facing, good loam soil rather than clay but very damp in the winter.
All suggestions greatly welcome!
