Creeping Bellflower (Campanula rapunculoides) has arrived in our yard. Which is not surprising since down the street the plant is being encouraged in a flower bed. Hopefully they will not cause too much trouble. Thankfully it was around the lilac tree in the lawn and not the flower bed.
Note to fellow gardeners: please pull out this notourious weed and don't be tempted by NEW and exciting exotic flowers that are the potential next invasive weed for us to deal with. Focus on native or near-native species where possible.
