It thrives in full sun to semi-shade, with regular watering. The delicate, fragrant lavender and purple flowers that the bush produces attract butterflies and hummingbirds. Although the plant is invasive, it is also a mature plant that is cold hardy at least down to 30s F for a short period of time, and is flood tolerant. This makes it relatively easy to grow in USDA zones 9-11.

When it comes to growing the blue butterfly-bush in a pot, it should be noted that it can be done in colder regions provided certain conditions are met. The soil should be moist at all times and the pot should be placed in a sheltered spot to prevent frost damage. A good winter mulch will also help to insulate the roots and keep them warm. If you are living in an area with cold winters, it may be best to bring the pot indoors for the duration of the winter season.
