If you're planning your own butterfly garden, or looking to add to it, keep in mind that most of these plants do well in full sun (with the exception of impatiens). Now is a good time to add some of these perennial plants and annuals to your garden. I'm still working on this myself. Most of the plants pictured were planted recently, and some more are waiting in flats, ready to be planted today.
Also listed are trees and shrubs, although keep in mind these are probably best planted in the fall.
Finally, remember that butterflies are insects, so insecticide will kill them! Avoid use of any nasty chemical insecticides. Biological controls are recommeneded, although I haven't tried this yet myself. Insecticidal soaps are less harmful, but I use this only on the roses (which tend to attract bees, not butterflies).
