|What is the best Buddleia to attract the most Butterflies?
|There are many cultivars of Buddleia davidii, and exact plant characteristics will vary. Growing conditions will also have an impact on the plant's mature size. But generally speaking, Buddleia davidii can get 6'-12' tall and have a spread of 4'-15'. Blooms on the plants can be purple, pink, white, or red, and they usually have an orange "throat" in the center. All attract butterflies but the purple flowring species is particularly adept at attracting tiger swallowtails. It also attracts hummingbirds and bees so I think it's perfect for the garden.
