Also known as false campanula, ladybells (Adenophora) sports tall spikes of attractive, bell-shaped flowers. Adenophora ladybells are attractive, elegant, easy-to-grow plants often grown in borders. Read on for Adenophora plant info and learn the specifics of growing false campanula in gardens.
Adenophora Plant Information
There are at least ten species of Adenophora ladybells. However, the most common include purple ladybells, which produce blue flowers and grows in USDA zones 7 to 9. Common ladybells, with droopy blue flowers, and lilyleaf ladybells, with blue or white hanging blooms, are both hardier plants suitable for zones 3 through 7.
Lilyleaf ladybells and purple ladybells reach heights of 18 to 24 inches at maturity, while common ladybells display sturdy spikes of 24 to 36 inches.
Growing False Campanula in Gardens
False campanula is difficult to transplant or divide due to the long roots, but it’s easy to grow from seed in spring or fall. You can also propagate false campanula by taking stem cuttings from mature plants in late spring.
Although it tolerates partial shade, Adenophora ladybells prefer full sunlight. Average, well-drained soil is suitable for most species.
How to Care for Adenophora Ladybells
Caring for ladybells is uninvolved, but here are a few helpful tips:
Irrigate regularly during the warm summer months, but be careful not to overwater. Ladybells exposed to hot afternoon sunlight may need a little more water.
Deadhead plants regularly to encourage more blooms. Deadheading also keeps the plant tidy and prevents rampant reseeding.
Fertilizer is optional, although the plant may benefit from a dry, time-release fertilizer applied in spring.
Cut plants near the base in fall or spring. Spread a layer of mulch around the plants in autumn if winters are cold.
Adenophora ladybells are generally pest and disease resistant. However, slugs may be a problem.
Are Ladybells Invasive?
Invasiveness depends on the species. Most, including the three species mentioned above, aren’t considered invasive, but they can definitely be aggressive. Regular deadheading immediately after blooming is critical if you don’t want seeds to scatter throughout your garden. The plant may also spread by runners, but the roots tend to grow slowly so this usually isn’t a major problem.
Creeping bellflower (Campanula rapunculoides), however, is a separate species that escapes cultivation in a hurry. This bully spreads by seeds and by aggressive underground roots. Think twice before starting this thuggish plant in your garden. Once established, creeping bellflower is extremely difficult to get rid of because even small pieces of root can begin a new plant.
