Tiara™ Royal Purple Aster

Tiara™ Royal Purple is a vigorous New York aster selected for richly colored purple flowers and seasonal impact. [Syngenta’s numbered cultivar listing](https://www.syngentaflowers.com/ams/product/flower/70089407) identifies selection 70089407 as Royal Purple and lists full sun, summer-to-fall flowering, and potted production. ## Garden use and seasonal interest Use this aster in a sunny container or seasonal border where its purple flowers can carry color from summer into autumn. The open, daisy-like flowers are characteristic of the [Royal Van Zanten Tiara series](https://www.royalvanzanten.com/en/concepts/tiara/), and its color makes it a useful late-season accent. ## Siting and care Provide a sunny position and soil that drains freely. [NC State Extension’s New York aster profile](https://plants.ces.ncsu.edu/plants/symphyotrichum-novi-belgii/common-name/new-england-aster/) describes the broader species group as suited to full sun or part shade and moist, well-drained soil; avoid leaving container roots saturated. Syngenta’s listed 9a–11a range is a commercial production range, so confirm local winter performance before relying on this plant to return outdoors. ## Maintenance Keep containers evenly moist during active growth and remove faded flower heads as needed for a neat display. Maintain airflow around dense growth and water at soil level.
