Notes
Bellflower (Campanula isophylla) is a perennial for containers, rock gardens, and borders. It is hardy to USDA zone 7, or down to 0°F (-18°C). This plant likes full or part sun and average to moist, sandy or loamy soil. Its cascading stems grow fast and spill over walls and pot edges. Blue, purple, or white flowers appear in early to late summer and again in early to late autumn. Bees, butterflies, and hummingbirds visit the blooms.
Pairs well with Gaura, Japanese forest grass, and Casa Blanca lily.
