Symphyotrichum oblongifolium 'October Skies' (Fragrant Aster)

Compared to 'Raydon's Favorite' this selection is a bit shorter and more blue/lighter purple. It provides just as much late season activity in the garden.  Tough as nails and can take some pretty horrible garden conditions like drought, poor soil, and heat.  This selection was discovered at the Scott Arboretum just outside of Philadelphia.
