Showmakers® Blue Bayou Aster

Showmakers® Blue Bayou is a New York aster bred as a decorative potted-flower cultivar with dark blue blooms. [Syngenta Flowers](https://www.syngentaflowers.com/ams/product/flower/70089412) classifies the flowers as blue and lists full sun and summer-to-fall flowering; the breeder lists medium vigor and a six-week reaction time. ## Seasonal display and placement Syngenta identifies the exact product as Aster novi-belgii Showmakers® Blue Bayou, code 70089412, and lists full sun, summer and fall flowering, blue flowers, and a potted-plant category. Its breeder, [Royal Van Zanten](https://www.royalvanzanten.com/en/products/potted-plants/aster/showmakers-blue-bayou/), calls the flower color dark blue and describes a decorative flower form with medium vigor. Together these product sources support using the cultivar for late-season color in a patio pot or sunny border. ## Growing conditions The species is a herbaceous perennial in the Asteraceae family. [North Carolina Extension](https://plants.ces.ncsu.edu/plants/symphyotrichum-novi-belgii/) says New York aster grows in sun or partial shade, prefers well-drained soil and attracts bees and butterflies. Those care and wildlife points apply at species level; Syngenta’s exact-product guidance specifies full sun. In a container, use a free-draining potting medium and check moisture more often than in a garden bed. ## Maintenance Water during establishment and when the root zone begins to dry, while avoiding standing water. Keep plants spaced for airflow and monitor for powdery mildew, which North Carolina Extension notes can affect the species. Remove spent stems after flowering, and leave room for the plant to develop rather than relying on repeated shearing.
