Vivid Magenta Blooms When the Garden Needs Them Most

Showmakers Magenta Aster (Symphyotrichum 'Showmakers Magenta') smothers itself in bright magenta, yellow-centered daisies in late summer and fall, just as most perennials wind down. This native-type aster is a critical late-season fuel stop for migrating monarchs and native bees, and its tidy, mounded habit keeps it looking neat in borders and containers. A pollinator powerhouse for Edina, Maple Grove, and Woodbury fall gardens.

Landscape Uses

Use Showmakers Magenta in pollinator and native gardens, mixed borders, and containers for a burst of late-season color. It pairs beautifully with ornamental grasses, sedum, and goldenrod for a classic fall combination.

Best Time to Plant

Plant in spring or early fall. Spring planting gives the longest establishment window before winter.

How to Plant

Dig a hole twice as wide as the root ball and just as deep. Set the crown level with the soil, backfill, water in well, and mulch 2–3 inches deep, keeping mulch off the stems.

Watering

First Year: Water deeply 1–2 times per week to establish the roots.
After Year One: Water during dry spells. Asters are fairly drought tolerant once established but bloom best with occasional water.
Drip Irrigation: A drip line keeps moisture even without wetting foliage, which helps prevent mildew.
