Plants are dispatched in growing condition and may not be in full flower. If too tall to pack safely, we may cut them back — this helps them establish more quickly. Read our Mail Order FAQs.
Symphyotrichum oblongifolium ‘October Skies’ produces soft lilac-blue daisy flowers with warm yellow centres over grey-green foliage from late summer into autumn. Compact and bushy in habit, it forms a neat clump of lance-shaped, slightly hairy leaves on upright stems and is notably more drought tolerant than most asters.
Well suited to the front of a border or gravel garden, it combines well with ornamental grasses, Hylotelephium, and other autumn-flowering asters. It thrives in fertile, moist but well-drained, neutral to alkaline soil in full sun or partial shade. Mulch in autumn and avoid sites prone to winter waterlogging.

Care Guide:
Divide clumps every 3–4 years to maintain vigour — any time after flowering but spring is preferred. Cut back stems after flowering in autumn. Taller selections may require staking. Symphyotrichum novi-belgii cultivars benefit from good air circulation to help prevent mildew.
