Campanula 'Sarastro'
bellflower
One of the tallest bellflowers, this is a real showstopper, with a long flowering period and the added advantage of being low-maintenance and easy to grow. From early summer to early autumn magnificent, large, deep purple, pendent, bell-shaped flowers, 5cm long, appear on tall stems above rosettes of large, hairy leaves.
A clump-forming perennial, Campanula 'Sarastro' is a real asset to a cottage-garden scheme, or a scheme based on blues and purples. Or simply use it to add height to a mixed border.

How to care for Campanula Sarastro:
Plant in full sun or light shade, in moist but well-drained soil enriched with organic matter. Space them with good airflow to help prevent mildew, and water during prolonged dry spells, especially in their first season. Protect emerging foliage in spring from slugs, which can cause early damage.
Stake with brushwood or canes early in the season to support the upright stems. Apply a 5-7cm (2-3in) mulch of well-rotted compost in spring to retain moisture and suppress weeds. Deadhead regularly to extend the flowering period and reduce unwanted self-seeding. Cut back the faded flowering stems in late summer to neaten the plant and encourage possible late blooms. Divide congested clumps in spring or autumn to maintain vigour.
