    Aromatic Aster (Symphyotrichum oblongifolium) 'October Skies' is a low-growing aster with light blue lavender blossoms that appear in late summer to early fall. 'October Skies' spreads out rather than growing tall. It is a nectar source for butterflies and has special value to native bees. Aromatic aster also supports conservation biological control by attracting beneficial insects to the garden. The seedheads may be enjoyed by birds.

    Aromatic aster 'October Skies' is tough as nails and a beautiful addition to the fall garden. In Tennessee, it can bloom well into November.
