Butterflies are magical. When first considering the plants you will put into your garden, know that butterflies are attracted to large splashes of color. However, if your intention is to keep them around you'll need to supply them with what they like to eat. This is not to undermine the importance of plants that encourage butterflies to lay their eggs. Butterflies like Great Swallowtail, Monarch, Painted Lady, Tiger Swallowtail, Red Admiral, etc. have particular plants that will attract them.
