Butterfly Bush

Buddleia davidii

Butterfly Bush Plant Features

As fragrant as it is beautiful, buddleia, commonly called butterfly bush, is must-have plant for your garden. Available in standard varieties that grow 6 feet tall and dwarfs that top out at 18 inches, you'll find a butterfly bush that's perfect for any sunny spot in your landscape. The long flower spikes of colorful, nectar-rich blooms appear all summer long and will attract hordes of butterflies and other pollinators. Butterfly bush is also drought tolerant and relatively disease free.

Butterfly Bush Growing Instructions

Plant butterfly bush in a sunny spot where it will receive at least 6 hours of direct sun a day. The plants aren't fussy about soil type, but do best in a rich, well-drained location. Fertilize in the spring with an application of granular, slow-release fertilizer. Use standard varieties of butterfly bush in the back of the border where their height will show to best effect and plant dwarf varieties along a garden path or in containers. Although butterfly bush is attractive to adult butterflies, it has no food value for native caterpillars so be sure to include other species to support them.

In the northern part of its range butterfly bush will often die back to the ground. Be patient in the spring because these plants are slow to break dormancy. After a severe winter you may need to replant. Also, in some locations, butterfly bush can become invasive so look for newer sterile seedless varieties. 

Butterflies love to feast on butterfly bush flowers, but don't try it yourself. It's not an edible plant.
