Supercal Light Yellow Petchoa (Petchoa 'Supercal Light Yellow')
Petchoa 'Supercal Light Yellow'

Evergreen Perennial (usually grown as an annual near you) Mounding, Trailing in the Solanaceae Family
A soft yellow petchoa with an ombre fade from a darker gold eye to pale yellow edges.

SuperCal® Light Yellow Petchoa (Sakata Seed Corporation's breeding code 'SAKPXC017', US Plant Patent 28,612, granted 2017) is a Petunia × Calibrachoa hybrid (×Petchoa) grown for its light yellow blooms, which fade in an ombre effect from a darker gold eye and yellow-green veins near the throat to pale yellow at the petal edges. It has a mounding, somewhat trailing habit, blooming continuously from spring through the first fall frost. The patent's own trial measurements reflect a young plant; mature retail container size is somewhat larger, consistent with its siblings in the SuperCal line. Like other petchoa hybrids, it is self-cleaning - spent flowers drop cleanly without deadheading.

Pros

  • Self-cleaning - no deadheading required
  • Continuous bloom from spring through the first fall frost
  • Vigorous, trailing habit ideal for hanging baskets and containers
  • Good heat and rain tolerance once established

Cons

  • Not winter-hardy in Chicago - grown here strictly as a warm-season annual
  • Dislikes soggy, poorly-drained soil
  • May need an occasional mid-season trim for the best rebloom
This plant is probably not winter-hardy outdoors where you live.
Highlights Light yellow, ombre-effect blooms with darker veining and eye; US Plant Patent 28,612; self-cleaning, no deadheading needed.
 

Plant Data

Mature Size 10 - 16 inches tall. 14 - 20 inches wide.
Sun Exposure Partial Sun - Full Sun
Moisture Tolerance Medium : Prefers evenly moist, well-drained soil. Avoid letting the root ball dry out completely between waterings, but don't let it sit in standing water or soggy mix - overwatering in poorly-drained containers is the most common way to lose this plant. Container and hanging-basket plantings dry out faster than in-ground beds and need more frequent watering, especially in hot weather.
Zones 10a - 11b (Usually hardy to 30° F)

Commonly Planted with...

An excellent 'spiller' for the edge of mixed containers and hanging baskets - pairs well with upright 'thriller' plants (e.g. ornamental grasses, Angelonia, or upright Coleus) and other mounding 'filler' annuals in a classic thriller-filler-spiller combination. Also effective massed on its own in window boxes.

Field-Grown vs. Greenhouse-Grown Plants

Plants which are well-adapted to our local climate are most often field-grown (outside). Field-grown plants are generally cheaper and have the advantage of already somewhat acclimated to our cold winters, but that means they’re not artificially far along in the spring and tend to bloom at the normal time in our area.

Spring annuals and tender perennials are typically grown in Greenhouses so they can be ready and luxurious exactly when customers want them. Some perennials are also “forced” into early bloom in greenhouses. In May, there can be a very big difference between field-grown and greenhouse-grown plants of the same type. The latter typically look good right away (so they’re a great choice where that’s important), but we typically pay a premium for it.

No Pricing or Availability Right Now

We order from a rotating cast of the best nurseries in the Great Lakes region. It looks like we've offered this plant in the past, but the nurseries we're working with this week don't appear to have it in stock at the moment.

Our goal is to bring as many plants together under "one roof" as possible, so we'll try hard to make it available again in the future!
