Vanna™ Snow Chrysanthemum

Vanna™ Snow is a white, daisy-form garden mum selection listed in Syngenta’s shaded program for both small and large production containers. Iowa State Extension describes garden mums as fall-blooming plants and recommends spring planting where they are to establish outdoors. [Syngenta Shaded Program](https://www.syngentaflowers.com/ams/sites/g/files/kgtney2381/files/file_field/import/field_media_link/sites/g/files/zhg721/f/gardenmumshadedprogram_0.pdf) · [Iowa State Extension](https://yardandgarden.extension.iastate.edu/how-to/growing-chrysanthemums-iowa) ## Placement and season Use this named selection in a sunny container or garden display, leaving enough room for air movement and mature growth. The Syngenta program identifies it with daisy mums and notes a late six-to-seven-week shade response for its production grouping; that is a grower scheduling measure, not a promise of a fixed outdoor flowering date. Full sun, moist well-drained soil, and even moisture support garden mums. Iowa State recommends spring planting in its climate so roots have time to establish before winter; local season length and winter survival depend on site and climate. [Iowa State growing guidance](https://yardandgarden.extension.iastate.edu/how-to/growing-chrysanthemums-iowa) · [NC State Plant Toolbox](https://plants.ces.ncsu.edu/plants/chrysanthemum/) ## Maintenance Water consistently while plants establish and through dry periods, without leaving roots in poorly drained soil. For a bushier garden mum, Iowa State advises pinching young shoots in spring and early summer and stopping by early July in Iowa, since later pinching can delay flowering. That calendar is regional guidance, so adjust it to local growing conditions. Remove spent flowers for a tidy display; consider dividing established garden-mum clumps every few years if they become crowded.
