Bellflower

Campanula waldsteiniana | Also known as: Campanula | Rating: 0 votes | Print / Pdf

Campanula waldsteiniana or the waldstein bellflower may be a low-growing plant but it doesn’t keep a low profile with its incredible purple-blue flowers that have an open bell shape and are supported on slender stems above toothed ovate to lance-shaped green leaves. Suited to gritty and fertile soils with good drainage, this plant appreciates full sunlight but will grow in partial shade too. The waldstein bellflower is striking within a rock garden but don’t rule it out if you have a small outdoor space as it can also be grown in a container, making it a stunning choice for a patio or a compact courtyard.
