Plant Overview

Smooth Aster is a stunning native perennial that adds vibrant color to late-season gardens. With its masses of violet-blue daisy-like flowers blooming from August through October, this hardy plant attracts pollinators and provides essential late-season nectar for butterflies and bees.

Plant Care

Smooth Aster is remarkably low-maintenance and drought-tolerant once established. Deadhead spent blooms to encourage continuous flowering and prevent self-seeding. Cut back stems to ground level in late fall or early spring. Division is recommended every 3-4 years to maintain plant vigor and prevent center die-out.

Planting Instructions

Plant in spring or early fall, spacing plants 18-24 inches apart. Dig a hole twice the width of the root ball and at the same depth. Remove the plant from the container and gently loosen the roots. Place in the hole, ensuring the crown is level with the soil surface. Backfill with soil, water thoroughly, and apply a light layer of mulch around the base, keeping it away from the crown.
