Summer Wave Large Silver Wishbone Flower (Torenia 'Summer Wave Large Silver')
tor-EE-nee-ah 'Summer Wave Large Silver'

Annual (usually grown as an annual near you) Trailing in the Linderniaceae Family

Summer Wave Large Silver is a trailing Suntory-bred Torenia with soft, pale lavender-blue flowers, blooming from planting until the first frost. Like its Large-series siblings, it cascades well in hanging baskets and prefers part sun to part shade.

Pros

  • Trailing habit good for hanging baskets
  • Unusually pale, soft flower color versus typical deep purple/blue Torenia
  • Long bloom season

Cons

  • Prefers part sun to part shade; less sun-tolerant than some Large-series siblings
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.

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!
