Campanula isophylla – STAR OF BETHLEHEM

Star of Bethlehem is a pretty flowering plant which can produce hundreds of blooms, especially in its second year. It has an orderly, bushy shape and bears attractive bell-shaped flowers, usually blue, but sometimes white. The leaves are clear green and heart-shaped with serrated edges. It is quite easy to grow.


Growing season 15-22 °C (60-72 °F)star-of-bethlehem-campanula

Minimum winter 7-8 °C (45-46 °F)

Soil: A soil-less compost. Use a very weak feed. Where to position: In good light; not strong sunlight. Avoid draughts and temperature changes; the flowering will be better.

Watering requirements: Keep the soil in a moist condition. It needs no spraying or special humidity provisions.

General care: With modest care, this plant can be covered in flowers. Feed weekly when in bud or in flower, with weak liquid fertilizer. Pick off faded blooms to stop seeds forming and weakening the plant. Use a good-sized pot.

Rest and care: When flowering stops, cut the plant down to around 4 ins and stand it in a good light, in a cool, frost-free place. Water very sparingly; keep soil just moist. Re-pot in spring and start into growth again in a slightly warmer spot. Step up watering slowly. Re-start feeding as growth becomes strong.

When it looks sick:

The plant looks unkempt and tatty : The likely cause is bright sunshine. Screen it from the sun’s rays.

The plant wilts: Correct soil condition to a springy texture; it may have been over or under-watered.

Yellowing leaves: These may result from over-feeding. Have you been too liberal? If not, suspect drainage. This can often be improved without unduly checking the plant. Tap it from the pot, place crocks in the bottom of one slightly larger and replace the plant filling the gap with fresh soil.

Blotchy, sticky-looking leaves : Check for parasite attack.
