Erigeron 'Azure Beauty' is an easy, free-flowering perennial with large light lavender-blue daisy flowers with yellow centres from June to August. Attractive to butterflies and good as cut flowers. Height and spread 45cm. Ideal for the front of a herbaceous border in well-drained soil which does not dry out in summer, in a sunny position. Deadhead to prolong flowering. Cut down to the ground in autumn. Lift and split in spring every few years to maintain vigour, discarding the woody pieces in the centre.
