Endless Illumination Browallia (Browallia 'Endless Illumination')
bro-WAL-ee-ah 'Endless Illumination'

Annual (usually grown as an annual near you) Mounded in the Solanaceae Family

A shade-loving Proven Winners annual with vivid violet-blue flowers from spring through frost -- no deadheading needed.

Browallia speciosa 'UNHBR12' (Endless™ Illumination) is a compact, mounding selection in the Endless series bred by Rosanna Freyre at the University of New Hampshire and introduced through Proven Winners. It produces a profusion of vivid violet-blue, star-shaped flowers over glossy green foliage, blooming continuously from spring through frost with very little seed set and no deadheading required.

Browallia speciosa itself is a tender tropical perennial native to Colombia, Ecuador, Peru, and neighboring parts of South and Central America, grown throughout the Chicago area as a shade-garden and container annual.

Pros

  • Blooms continuously from spring through frost with no deadheading needed
  • One of the few true annuals that thrives in partial to full shade
  • Vivid violet-blue flowers are an unusual, true-blue color among shade annuals

Cons

  • Tender tropical perennial grown as an annual; will not survive a Chicago winter outdoors
  • Flowers best with consistent moisture and can decline if allowed to dry out
  • Will scorch in full sun, limiting it to shadier sites
This plant is probably not winter-hardy outdoors where you live.
Highlights Award Winner Continuous Bloom or Rebloomer Heat Tolerant Deadheading Not Necessary

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!
