Gold Dust Mecardonia (Mecardonia 'Golddust')
Mecardonia 'Golddust'

Perennial (usually grown as an annual near you) Trailing, Mounding in the Plantaginaceae Family

GoldDust Mecardonia is a compact, trailing selection prized for its nonstop show of small, golden-yellow, nemesia-like flowers over lush green foliage from planting until the first frost. Its cascading habit makes it a natural choice for hanging baskets, window boxes, and the edges of mixed containers, where it spills gracefully over the rim, and it works equally well as a low, flowering groundcover in sunny garden beds. Thriving in full sun and well-drained soil, it shrugs off heat and short dry spells once established, needing only routine watering to keep flowering all summer.

Pros

  • Award-winning selection with months of nonstop golden-yellow flowers
  • Self-cleaning -- no deadheading required
  • Heat tolerant and easy to grow in beds, baskets, or containers
  • Fast, trailing habit spills gracefully over container edges

Cons

  • Not cold-hardy outside zones 10a-11b; grown as an annual elsewhere
  • Needs fairly consistent moisture, especially in containers
This plant is probably not winter-hardy outdoors where you live.

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.

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!
