All B. davdii cultivars require weekly deadheading for them to look and bloom its best.
Butterfly bushes may be good nectar sources for adult butterflies, but they are not food sources for the caterpillars of any Lepidoptera native to the continental US.
In some places, B. davidii can be an invasive weed: England, France, New Zealand, and the states of Oregon and Washington. It has naturalized in eastern N.

If it can survive our rough handling of it, it can survive anything!
