Ajuga - aggressiveness of
I've planted some Ajuga Chocolate Chip in my semi-shady parking strip. Also there are aspidistra and a recently planted choisya ternata 'Aztec Pearl'. I know ajuga can be sort of aggressive. Could it be aggressive enough to overwhelm the other plants I have there?
Should I add some sort of root barrier around the other plants? The fellow at the nursery advised me against planting vinca minor because of it could swamp other plants so that's why I went for the ajuga reptans.
Also, is it conceivable that ajuga could creep under the sidewalk and emerge on the other side? This may be the silliest question of the year...or not. I'll wait to find out.
