Campanula isophylla

Phonetic Spelling
kam-PAN-yoo-lah eye-so-FYE-lah
Description

Campanula isophylla is a tender perennial, only marginally frost hardy and often grown as an annual or houseplant. They need about 15 hours of daylight before flower buds will develop. Supplementary artificial light can induce the plants to bloom a little earlier in summer. They require consistent moisture and hey should be watered regularly to keep the potting mixture thoroughly moist but without standing water. Be careful when handling the stems and leaves as they are very brittle.
