Superbells® Double Redstone Double Calibrachoa

Superbells® Double Redstone is a mounding, trailing calibrachoa with fully double vermilion-red flowers edged in gold. The [Proven Winners cultivar profile](https://cdn6.provenwinners.com/plants/calibrachoa/superbells-double-redstone-double-calibrachoa-calibrachoa) lists a 6–12 inch height, 12–24 inch spread, and spring-to-fall flowering. ## Flowers and placement The red petals and fine golden edges create a bright pattern in hanging baskets, window boxes, and mixed containers. Use the stems as a spiller over a planter rim or repeat the compact plants along a sunny bed edge. This tender perennial is generally grown as an annual in cooler climates; the breeder lists USDA zones 9a–11b. ## Growing conditions Set the plant in full sun to part sun and use a fertile, well-drained potting mix. [NCSU Extension](https://plants.ces.ncsu.edu/plants/calibrachoa-x-hybrida/) recommends moist, organically rich soil for calibrachoa while cautioning against wet roots; [Illinois Extension](https://extension.illinois.edu/flowers/calibrachoa) advises regular watering and feeding, especially for containers. Water when the mix begins to dry slightly and keep the pot from standing in water. ## Maintenance Feed during active growth according to the fertilizer label. The flowers are self-cleaning, so routine deadheading is unnecessary. If stems become uneven, shorten the longest shoots lightly and continue regular care.
