Use the plant water needs as a guideline. Actual plant water needs will vary for several reasons, including weather conditions, soil type, sun exposure, root depth, wind and elevation. Adjust your watering schedule as needed to meet the plants' needs at your site. Water recent transplants more often than established plants.

Butterfly bush is a somewhat irregularly shaped, arching shrub. The flowers are arranged in cone-shaped clusters on the end of the stems and are very fragrant. The scent is very attractive to bees and butterflies. Flowers can be white, pink, blue or purple depending on the cultivar, each with a deep orange center.
Its leaf color is usually medium green. Butterfly bush is drought-tolerant, and is a colorful addition to gardens and landscapes. It has sometimes suffered dieback in exposed sites in the Colorado Springs area, so it needs a protected location to thrive.
Butterfly bush is growing at the Cottonwood Creek Garden and has been planted in a low water zone of the Mesa Garden for many years.
They have often died back part way over the winter. Nonetheless, the flowers are beautiful and support butterflies and bees. In a sunny, protected location, butterfly bush can be a good choice.
Remove winter-killed branches to the ground in spring.
