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.
