Bicolor Butterfly Bush (Buddleja x weyeriana 'Bicolor')
Buddleja ex weyeriana BY-kul-or

Deciduous Perennial Shrub in the Scrophulariaceae Family

Buddleja x weyeriana 'Bicolor' is part of the x weyeriana group (a hybrid of B. davidii and B. globosa first bred by Major William van de Weyer in England during WWI); this particular selection was raised in 1999 by Michael Dirr at the University of Georgia. Its dense flower clusters open a rich violet-purple and fade to a warm gold-orange, giving each spike a genuinely two-toned look, set off by gray-green foliage. Fast growing and sweetly fragrant, it blooms from midsummer into fall and draws butterflies and hummingbirds to the garden.

Pros

  • Genuinely bicolor flower spikes - violet-purple opening to gold-orange
  • Fast growing and sweetly fragrant
  • Blooms from midsummer into fall
  • Attracts butterflies and hummingbirds; deer resistant

Cons

  • Needs full sun to perform well
  • Dies back to the ground most winters in colder zones, regrowing from the base in spring
  • Benefits from deadheading to prolong bloom

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!
