Asters are in the daisy family and while some flower in spring, most flower in late summer and autumn, hence their common name Michaelmas daisy. Symphyotrichum laeve ‘Calliope’ is a particularly tall aster, bearing masses of small, lilac-blue flowers with yellow centres. It’s ideal for growing in herbaceous borders and makes a welcome flash of colour when other flowers are starting to fade. It’s also an important source of nectar and pollen for late-flying insects.
