Aster amellus ‘Blue King’ (also called Michaelmas daisy 'Blue King')
Herbaceous perennial with blue-lilac daisy-like flowers. Asters provide a splash of colour in autumn when many other plants have finished flowering. They are good for cutting. Reputed to be rabbit resistant. Attractive to bees, flies, beetles, moths and butterflies.
Flowers in late summer to autumn.
Upright, but fairly lax habit. May need support. H 30cm S 46cm
Leaves – mid-green, rough, oval.
Stems – straight to lax, round and green, sometimes a hint of red-brown.
Flowers – single, many-petalled daisy type flower. Blue-lilac petals, yellow centres.

Water regularly in summer. Deadhead to prolong flowering. Cut back to ground level after flowering and apply a generous mulch of compost. A. amellus is prone to damage by slugs, snails, aphids and mildew.
