Cosmic Galaxy Purple™ Chrysanthemum

Cosmic Galaxy Purple is a very late-season garden mum in Ball’s five-color Cosmic family, with purple decorative flowers and a European, mounded habit. Ball [lists it for autumn flowering and mixed containers](https://ballseed.com/Products/043100001052024/garden-mum-cosmic-galaxy-purple) and describes the Cosmic family as closely timed in flowering and habit. ## Landscape Use and Seasonal Interest Use Cosmic Galaxy Purple in a sunny autumn container, mixed basket, or landscape planting for late-season color. Ball describes the Cosmic family as suitable for pots, hanging baskets, and mixed containers. ## Size and Siting Ball lists this selection at 14–24 inches tall and 20–36 inches wide. Allow room for its spreading mound and place it in full sun. ## Soil and Water Choose fertile soil that drains well and retains even moisture. Water regularly during active growth and flowering, especially in containers, while allowing excess water to drain. Ball rates the plant for medium water needs. ## Maintenance Keep the root zone evenly moist during flowering and remove spent blooms as desired to tidy the display. [NC State Extension](https://plants.ces.ncsu.edu/plants/chrysanthemum-x-morifolium/common-name/mum/) recommends pinching garden mums in spring and early summer to encourage branching; stop pinching by mid-summer so flower buds can form. In colder regions, fall-purchased florist mums may be less reliable as long-lived perennials than plants established in spring.
