How Much Room Does a Butterfly Bush Need?
Butterfly bushes are medium-sized bushes that can reach up to 15 feet in height at maturity. The aggressive, fast-growing bushes should be pruned each year, but they'll continue to spread if not checked. Does this Spark an idea?

Mature Size
-
The bush grows from 5 to 15 feet in height and up to 10 to 15 feet in width. To allow the bush to spread out, plant butterfly bush 10 to 15 feet from other trees or other trees and bushes.
Container Species
-
For small spaces, plant a butterfly bush such as Lo & Behold Blue Chip. The cultivar makes a low-growing choice that's ideal for container gardens. The semi-evergreen and drought-tolerant bush reaches just 24 to 36 inches in height and up to 30 inches in width. You can also plant the smaller cultivar as a ground cover for sunny areas of the garden.

Hedges
-
Butterfly bushes make great hedges when they're planted close together. With consistent pruning, you can keep the bush at just 5 to 10 feet in height so it forms a thick hedge. In the winter, when the leaves fall off the bush, you may be able to see through the hedge, making it less ideal as a privacy screen during colder months.
