Campanula (Bellflower) Indoor Care: Charming Bells for Cool, Bright Spots

Campanulas—bellflowers—bring delicate, nodding bells in blue, violet, white, and pink to cool, bright interiors. With 300+ species from the Mediterranean to Asia, they range from tiny creepers to 2-foot uprights. Many adapt well to pots, trailing over edges or covering small trellises.

Easy Indoor Species

• C. carpatica – low mounds, spring bloom
• C. portenschlagiana – trailing, covers walls/pots
• C. isophylla – "Italian bellflower," trailing, long bloom
• C. glomerata – clustered "superbells"

Light and Temperature

Bright, indirect light. Cool temperatures: 60–68°F (15–20°C) active; 45–50°F (7–10°C) winter rest. Heat causes rapid decline.

Water and Soil

Moist, well-drained soil. Water regularly in growth; keep barely moist in winter rest. Feed twice monthly in summer with bloom booster.

Winter Rest

Essential. Cool, bright, nearly dry. Without it, plants weaken and stop flowering.

Pests

Aphids and spider mites in hot, dry conditions. Mist and inspect regularly.

Propagation

Division in spring, or basal cuttings. Seeds for species types.
