Butterfly Bush (Buddleja davidii)

The Butterfly Bush, scientifically known as Buddleja davidii (often spelled Buddleia), is a popular shrub celebrated for its vibrant flowers and ability to attract butterflies, hummingbirds, and beneficial insects.

Common Names

  • Butterfly Bush
  • Orange-eye Butterfly Bush
  • Summer Lilac

Taxonomy and Nomenclature

  • Scientific Name: Buddleja davidii
  • Genus: Buddleja (also historically given as Buddleia)
  • Family: Not specified in the text.

Distribution and Habitat

Originally from China, Buddleja davidii has been widely planted. It thrives in U.S. Department of Agriculture plant hardiness zones 5 through 10.

Ecological Role

The Butterfly Bush is considered an invasive species in some regions. This means it can outcompete and crowd out beneficial native plants. Some varieties, like 'Lo & Behold', are being developed to not set seed and therefore be non-invasive.

Morphological Characteristics

The Butterfly Bush is described as:

  • A large, arching shrub
  • Fast-growing
  • Deciduous to semi-evergreen
  • Reaching a height of 8 to 10 feet or up to 5 meters
  • Produces masses of flowers in midsummer to fall
  • Flower colors include blue, pink, red, violet, yellow, and white
  • Has flower spikes that drench the air with a fruity scent
  • Some varieties are dwarf

Quirky Facts

  • The text highlights a debate surrounding the Butterfly Bush, suggesting varied opinions on its overall value in gardens.
  • The 'Lo & Behold' variety is noted as the first to not set seed, specifically addressing invasiveness concerns.

Interactions with Other Organisms

  • Highly attractive to butterflies, hummingbirds, and beneficial insects.
  • Provides only nectar, which some argue is not beneficial for birds and butterflies in the long run compared to native plants.
