The flowers of a butterfly bush grow in clusters a foot or two in length, and have side branches and blossoms.
As the name suggests, a butterfly bush is attractive to butterflies in the garden.
In fact, it is almost like a butterfly magnet. Butterflies will swarm to the brightly colored and fragrant blooms of a butterfly bush.
Bees and oftentimes even hummingbirds are attracted to the nectar of the butterfly bush.
A butterfly bush works in many settings in the garden. It can be planted in a row, making a lovely border for a perennial garden, and can even be used as an accent plant.
A butterfly bush is very easy to hybridize, and for this reason, volunteer seedlings may look nothing like their parent plant.
It is also important to try to prevent the spread of a butterfly bush, as it can become aggressive and kill neighboring plants.
