Butterfly Bush is a deciduous shrub that grows from 3 to 15 feet tall. This species is celebrated for its robust growth, fragrance, and range of bloom colors, and is often recommended for its ability to grow in poor soil and to attract butterflies. It is now considered an invasive species.

Flowers bloom between mid-summer and the first frost. These flowers have 4 petals and can be purple, white, or pink. The flowers produce high quantities of nectar and are attractive to butterflies. These shrubs also alter the nitrogen and phosphorus amounts in the soil.
