See lots of butterflies by planting a garden that will attract them. You can add plants to your yard if you have one, and plant a window box if you don't.   Grow flowering plants that attract local butterflies. Do some research online or in your local bookstore or library to identify these plants.   Include both the plants that adult butterflies collect nectar from and the plants that caterpillars eat.   If possible, let some dandelion and clover grow in your grass. Butterflies love them!   Plant your flowers in sunny spots. Also, provide rocks and stones for sunbathing butterflies!
