Grandalia™ Yellow Dahlia

Grandalia™ Yellow is a named Dahlia × hybrida in Syngenta Flowers’ Grandalia series. The Americas profile identifies code 70019190 and lists yellow flowers, upright growth, spring-to-summer flowering, and a size of 14–16 inches tall by 18–22 inches wide [for this selection](https://www.syngentaflowers.com/ams/product/flower/70019190). ## Site and care Set this medium-vigor plant in a bright, warm site; the profile allows part sun or full sun. Its upright stems and broader 18–22 inch spread suit a large container or a place in a mixed annual bed. Dahlias prefer fertile soil that remains moist but drains freely. The [RHS dahlia guide](https://www.rhs.org.uk/plants/dahlia/growing-guide/) advises additional watering in hot, dry weather and regular watering for container-grown plants. ## Seasonal interest Syngenta lists flowering from mid-spring through late spring and summer. Use the published dimensions as an approximate guide and leave enough room for the plant to fill out as it grows. ## Maintenance Water consistently during warm, dry periods while avoiding waterlogged soil. Deadhead faded flowers regularly to encourage additional blooms, as recommended by the RHS. Grandalia Yellow is the exact named selection represented by this record; retain its yellow color identity when planning combinations.
