Nikki™ Yellow Chrysanthemum

Nikki™ Yellow is Syngenta’s yellow-to-gold garden mum in the medium-vigorous Nikki™ family. Its decorative fall flowers bring a warm color to seasonal displays and mixed-color containers. ## Flowers and season The [Syngenta product page](https://www.syngentaflowers.com/ams/product/flower/70067027) identifies this selection as a garden mum, lists full sun and fall flowering, and recommends medium or large pots. Syngenta’s [2025 Garden Mum catalog](https://www.syngentaflowers.com/ams/sites/g/files/kgtney2381/files/media/document/2025/05/19/sf-17808-mumscatalog-final-300dpi-2024-07-09.pdf) describes the flowers as decorative and small to medium, with medium-large plant vigor. Syngenta describes the Nikki family as a good option for large tricolor pots and notes that high night temperatures can delay blackcloth crops. ## Siting Choose a sunny site. For garden planting, [Iowa State Extension](https://yardandgarden.extension.iastate.edu/how-to/growing-chrysanthemums-iowa) recommends at least six hours of direct sun and moist, well-drained soil. Its Iowa guidance favors spring planting to allow garden mums time to establish before winter. ## Maintenance Water regularly while plants establish and avoid wet, poorly drained ground. In Iowa, spring planting gives garden mums a better chance to overwinter; results depend on local conditions.
