Overview

Petchoa 'Caliburst Yellow' is a ground-breaking intergeneric hybrid that combines the best traits of Petunia and Calibrachoa. This cultivar is specifically celebrated for being the first solid yellow Petchoa from seed, offering the large, vibrant flower size of a Petunia with the high flower density and pH tolerance of a Calibrachoa. Its controlled, mounded habit makes it a premier choice for high-impact seasonal displays.

Plant characteristics

  • Mature size: 7 to 10 inches in height; 12 to 20 inches in spread.

  • Flower: Large, vibrant lemon-yellow trumpet-shaped blooms that cover the plant from spring until the first frost.

  • Foliage: Mid-green, oval-shaped leaves; notably less "sticky" than traditional petunia foliage.

  • Hardiness: Typically grown as a tender annual; USDA zones 9–11.

Light requirements

Full Sun is required for peak performance. At least 6 hours of direct sunlight per day ensures the plant maintains its compact shape and produces a continuous carpet of yellow blooms.

Water requirements

Requires regular watering to keep the soil consistently moist. While more resilient than standard Calibrachoa, 'Caliburst Yellow' should not be allowed to wilt completely. Ensure water is applied to the soil level to keep the blooms looking fresh.

Soil and drainage

Thrives in light, well-drained potting media or garden soil enriched with organic matter. Unlike some Calibrachoas that struggle with high pH, Petchoas are more adaptable but still prefer a slightly acidic environment (pH 5.5 to 6.2) for optimal nutrient uptake.

Fertilizer

This is a "heavy feeder." Apply a balanced liquid fertilizer every 1–2 weeks, or use a slow-release formula at planting. High iron levels in the fertilizer can help maintain the lush green color of the foliage.

Maintenance and pruning

'Caliburst Yellow' is largely self-cleaning, meaning it does not require constant deadheading to stay tidy. However, a "haircut" (trimming back by one-third) in mid-summer can help rejuvenate the plant and encourage a fresh flush of growth for the autumn.

Uses and design notes

Due to its mounding and slightly trailing habit, it is perfect for hanging baskets, window boxes, and premium containers. In the landscape, it functions beautifully as a vibrant groundcover or front-of-border accent. The bright yellow hue pairs exceptionally well with purple companions like Salvia or Angelonia.

Summary

Petchoa 'Caliburst Yellow' represents the pinnacle of modern breeding, offering gardeners the sun-bright intensity of a yellow petunia with vastly improved weather resistance and ease of care. It is a high-performance annual that provides reliable, season-long luminosity to any sunny space.
