How to Grow and Care for Wahlenbergia

Southern rockbell (Wahlenbergia marginata) is a perennial flower native to eastern and southern Asia which has also been naturalized in North America. It produces a carrot-shaped root and small, bell-like flowers that have earned it the additional nickname Asiatic bellflower.

New zealand harebell (Wahlenbergia albomarginata) is a flowering herb that is a popular ornamental plant for its five-petaled blue-white flowers. The Latin name albomarginata means white-edged in reference to these flowers. It is available in several hybrid forms. It is also known as "rock bell" for its liking for rocky habitats. Unsurprisingly, it is most commonly grown in rock gardens or containers.

The australian bluebell strongly resembles the Bluebell plant, but they are only distantly related. It is found growing wild all over Australia but is beautiful enough that it is often planted in gardens, either with the aid of nurseries or from wild-collected seeds.
