Campanula rotundifolia (harebell)

This delicate violet flower is a perfect addition to a cottage-style garden. The slender stem often bends with the weight of the flower. Blooms sporadically over several months. Deadhead to encourage more blooms. Pairs well with spring bloomers like pasque flower, prairie smoke, and wild strawberry. Also called witch's bells, Scottish bluebell, and lady's thimble. This plant is native to northern regions around the globe.

Tip: Avoid planting with tall, competitive plants.
