Dahlietta® Coby Dahlia

Dahlietta® Coby is a compact, mounded dahlia with green foliage and flowers in golden-yellow tones washed with orange. Ball Seed lists the Dahlietta series at about 10–12 inches tall and wide and describes Coby as a sunny plant with medium water needs and spring-to-late-summer flowering; other grower information highlights its two-tone flowers. ## Placement and color Plant Coby in a sunny container or small border, where the changing yellow-orange tones can stand out. Its rounded habit and modest size work well near paths and patios and among lower annuals. [Ball Seed’s Coby listing](https://info.ballseed.com/PlantInfo/?phid=021701289031001) documents the mounded habit, 10–12 inch size, sun exposure, bloom season, and wildlife characteristics. [Vite Greenhouses](https://www.vitegreenhouses.com/plantresults.asp?Query=55&hiddensearch=Dahlia+x) describes Coby’s soft golden-yellow and orange shades; a [Planter’s Palette profile](https://www.planterspalette.com/shop/c/p/Dahlia-Dahlietta-Coby-6-12-x32890400.htm) describes yellow petals dipped in orange. ## Soil and watering Choose fertile, moist but well-drained soil. Water in hot or dry periods and check pots frequently, since containers dry faster than beds. Avoid standing water around the roots. The [RHS dahlia guide](https://www.rhs.org.uk/plants/dahlia/growing-guide/) covers soil, sun, watering, and container care. ## Maintenance Deadhead faded blooms to prolong flowering. Dahlias are tender to frost; protect the tubers from freezing or lift and store them in a frost-free place after frost damages the foliage. See the [RHS overwintering guidance](https://www.rhs.org.uk/plants/dahlia/growing-guide/).
