Comments: This bellflower grows in sun or shade and is considered drought resistant. The plant spreads by underground runners and may become rampant on good sites. Although a trailing plant about 8 inches tall, it can grow to 3 feet if the stems are supported. The flowers are lavender blue and are more open and star shaped than other campanulas. Flowering occurs in June, July, or August.
Propagation: Division may be done in spring or fall. Seed may be planted outdoors in late spring or early summer with flowering occurring the following year. The seed is fine and may be hard to handle. Seed planted indoors germinates in 2 to 3 weeks.
