Hello, We have a large concrete planter bed (approx 3 metres by 1 metre) with a 25 year old Japanese maple in it and other less desirable plants. I'd like to keep the maple and was wondering if anyone has any suggestions of what to plant with maple that would be low maintenance? Deciduous or evergreen will do. Something to compliment the maple. Also, we have several large birch trees (bright white bark) planted in front of our condo. What could I plant around the base of the tree that would compliment the bark? Thanks!!
