A GARDEN PLAN for Butterflies IN THE SHAPE of butterflies from Birds & Blooms. Invite butterflies to your backyard with a butterfly-shaped garden plan filled with their favorite eats. For a fun way to attract them, try planting this butterfly-shaped garden. We have two plans to choose from: one a pairing of perennials, composed of host plants and nectar plants, and the other a feast of nectar-rich annuals. Before you know it, butterflies will be frequent guests at their new dining digs.
