Alexa™ White Chrysanthemum

Alexa™ White is a white-flowered garden mum (Chrysanthemum morifolium) from Syngenta Flowers, cultivar number 70119386. Syngenta describes it as a medium-vigor, full-sun selection with a midseason natural flowering response, a few days later than Addison™ White. ## Garden use and growing conditions Use the white blooms in fall containers, seasonal borders, or mixed plantings where a clear flower color complements richer autumn tones. Syngenta lists small-to-medium pots and hanging baskets. The cultivar page does not report a USDA hardiness zone or numeric mature landscape dimensions; local outdoor performance and spacing can vary. Garden mums need a bright site and fertile, organic-rich soil that is moist but well drained. Iowa State Extension recommends at least six hours of direct sunlight and notes that flowering responds to shortening days. Container plants need closer moisture monitoring than in-ground plants, while saturated soil can damage roots. Bloom timing depends on the cultivar’s natural response and local climate.

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