Identifying a Fall-Blooming Purple Bush: Need Photos for "Old English Aster"

"Old English Aster" Isn't a Standard Name

The term doesn't match known cultivars. True asters (Symphyotrichum) are perennials, not shrubs. Some are called "subshrubs" but stay low.

Likely Candidates for a Purple Fall-Flowering Shrub in Northern Indiana

• Beautyberry (Callicarpa) – Purple berries, not flowers.
• Russian Sage (Perovskia) – Lavender-blue flowers, subshrub.
• Blue Mist Shrub (Caryopteris) – Blue/purple late summer.
• Purple Smoke Bush (Cotinus 'Grace') – Pink-purple plumes.
• Fall-blooming hydrangea (H. paniculata) – Pinkish aging to purple.

Post clear pictures of flowers, leaves, whole plant, and size on a gardening forum (GardenWeb, Reddit r/whatsthisplant) or email to your Extension office. A cutting for propagation is a great idea once ID'd.
