Are butterfly bushes native?
Similarly one may ask, where are butterfly bushes native to?
It's not that butterfly bush is inherently a bad plant. It is native to China, not North America, Europe or New Zealand. The insects, birds and other residents with which it evolved in China and that depend on it for food there aren't present in the areas in which it was introduced.
Also, are butterfly bushes an invasive species?
Butterfly bush is an invasive plant, meaning it crowds out beneficial plants that have naturally grown in your community for centuries. In fact, Buddleja davidii (the scientific name for butterfly bush) has certain traits that make it invasive in most environments.
Buddleia is well-loved by butterfly gardeners because it is well-loved by butterflies. It blooms from spring to fall (depending on your growing zone), and produces an abundance of nectar-rich flowers that butterflies cannot resist. Butterfly bush is easy-to-grow and tolerates poor soil conditions.
