We have a property where the house is lower to the ground than the road. We have steps down into the front of the house and a retaining wall holding back the driveway. We have many issues with people looking into the house as they pass the road and would like to add a shrub for privacy above the retaining wall. We only have about 3-4 feet between retaining wall and the driveway. Hoping to find something that won’t destroy the wall but will still provide privacy. If possible something also low maintenance. Area is full sun, dry conditions, sandy/clay soils.
Below, you will find a link to a previous question posed to the Toronto Master Gardeners which you may find useful as all three shrubs mentioned would work very well in your situation and provide you with year round privacy.
I’m also giving you a link to our gardening guide on “Ornamental Shrubs for Various Light Conditions” where you will find other options, again see below.
Hope this helps.
