Aideen™ Red Fire Chrysanthemum

Aideen™ Red Fire is a named Syngenta garden mum, Chrysanthemum morifolium, catalog number 70021416. Syngenta describes it as compact-to-medium in vigor, red-flowered, and naturally flowering in fall; the breeder lists full sun, several container sizes, and a pollinator-friendly profile. ## Garden use and growing conditions The red flowers provide a strong seasonal accent in autumn borders and containers, and flowering stems can be cut for arrangements. Use this cultivar where its late-season color can contrast with grasses and other fading perennials. Syngenta does not report an outdoor hardiness zone or mature landscape dimensions for this selection, so check local cold tolerance and spacing with a supplier. Garden chrysanthemums perform best with ample light and fertile, organic-rich soil that holds moisture without becoming waterlogged. Iowa State Extension recommends at least six hours of direct sun and moist, well-drained soil; in warmer climates, afternoon shade may reduce stress. Flowering responds to shortening days, so the calendar date can shift with region and production conditions.

For garden-grown mums, Iowa State recommends pinching in spring and early summer and stopping by early July to avoid delaying flowers. Check winter performance locally before treating this cultivar as a permanent perennial.
