When choosing plants for your wall planter, look for types of succulents that will stay relatively small to best fill the heart shape. We used various types of Echeveria, Dischidia, and Haworthia cooperi, along with other succulents found at our local garden center to create a multi-textured and colorful arrangement. The trick to creating this stunning display is to prep your succulents at least a day before you start this project—these plants need a little time to develop scabs where the stems are cut. To prepare, simply remove succulent plants from their pots and brush away any excess dirt. Clip the stems so you have a long enough piece to insert into the floral foam that will fill your concrete form. Wait about a week before placing your hanging wall planter outdoors to give the plants time to anchor into their new home. Once you’re ready to hang, connect a length of chain to eye screws and secure each eye screw in the plastic anchors you inserted into the concrete during the molding process.
