Believer™ Purple Aster

Believer™ Purple is the purple color variety in Syngenta’s Believer line of New York asters. The breeder identifies it as Aster novi-belgii, code 70018144, with purple flowers in fall; its North American and EMEA profiles report different finished-plant heights, so size should be treated as a production estimate ([Syngenta North America](https://www.syngentaflowers.com/ams/product/flower/70018144), [Syngenta EMEA](https://www.syngentaflowers.com/emea/product/flower/70018144)). ## Form and Placement The cultivar has an upright, medium-vigor habit and suits sunny borders and containers for autumn color. Syngenta’s North American profile lists a garden height of 16–18 inches and width of 20–24 inches; its EMEA profile gives a height of 20–30 cm. Those regional figures differ, while retail listings may show a smaller finished plant, so use local stock and pot size to guide spacing ([Syngenta North America](https://www.syngentaflowers.com/ams/product/flower/70018144), [Syngenta EMEA](https://www.syngentaflowers.com/emea/product/flower/70018144), [Proven Winners](https://www.provenwinners.com/plants/aster/believer-purple-aster-novi-belgii)). ## Growing Conditions Provide full sun and moist, well-drained soil. New York asters also tolerate part shade; general species guidance recommends moist, well-drained conditions and periodic division for established clumps ([The Morton Arboretum](https://mortonarb.org/plant-and-protect/trees-and-plants/new-york-aster/)). Syngenta lists fall flowering and no USDA zone on its North American product page; Proven Winners gives a cultivar range of zones 3a–8b ([Syngenta North America](https://www.syngentaflowers.com/ams/product/flower/70018144), [Proven Winners](https://www.provenwinners.com/plants/aster/believer-purple-aster-novi-belgii)). ## Maintenance Water consistently during active growth and flowering, allowing excess water to drain. Remove spent stems after flowering and discard damaged foliage. Divide established landscape clumps in spring when crowded; in containers, refresh the growing medium and remove the plant after its display if it is being used as a seasonal crop.
