Height 23cm (9in)

Planting distance 15cm (6in)

Flowers early summer to early autumn

Well-drained garden soil

Sunny situation

Hardy annual

The intense blue bell-shaped flowers of Phacelia campanularia make this hardy annual an attractive addition to a rockery or unusual edging for a border. Appearing from early summer to early autumn, the flowers are carried on 23cm (9in) high plants with lush green irregularly toothed leaves. When these are crushed they give off a strong but pleasant fragrance.

Bees find the blue flowers parti-cularly attractive.


Sow the seeds in the flowering site in early to mid spring, just covering them with soil. Thin the seedlings to 15cm (6in) apart.

In a warm sheltered garden the seeds can be sown in early autumn for earlier flowering plants. Protect them with cloches during the winter.

Phacelia will grow in any well-drained and light soil and thrive especially in sandy soils. The situation must be sunny.

Pests and diseases

Slugs may eat the seedlings.
