Nothing says the tropics like the beautiful flowers from frangipani or plumeria (Plumeria alba) plants. Their smell is almost intoxicating; available colors are as vast as the rainbow. Highly prized by gardeners around the world, full-grown plants can fetch a price of several hundred dollars. Despite their delicate beauty the U.S. Department of Agriculture plant hardiness zone 10-to-12 perennials are fairly easy to grow, as cuttings are quite forgiving of neglect and drought. These are perfect plants for the black-thumbed or lazy gardener.
Allow your frangipani cuttings to dry out before planting. This is especially true if you are working with fresh cuttings. The cut ends need to scar over before you place them in the ground. Allow your cuttings to dry out for anywhere from three days to a week. Lay them on a table, or on the ground where you cut them, exposed to the air so they can "cure" for planting.
Fill a 3-gallon container with potting mix or sand. Frangipanis aren't too fussy about having a rich medium to grow in. In fact, if you use a medium such as potting soil, the cuttings may rot before they grow roots; potting soil has a tendency to retain too much water, and doesn't drain efficiently enough for frangipani cuttings to properly root. Use a potting medium that has good drainage and won't retain too much water.
Dig a 4-inch hole in the soil in the center of your container. Frangipani cuttings can be relatively heavy, so plant your cutting deep enough that it can stand up on its own. If your cutting is large, use a bigger container and a deeper hole.
Place your frangipani cutting into the hole, scar-side down. If the cutting has leaves attached to it, don't worry about pulling them off. The leaves will not impede the cutting's rooting process. Pack the soil firmly around the cutting, and make sure it is able to stand upright on its own.
Water your planted frangipani cutting. Pack the soil once again if the water loosens it. Water the container every three to four days, until the roots have started to establish themselves. Place your container in an area that gets full to partial sun. Frangipanis are very tolerant of drought conditions, so it's okay if the soil is dry for several days to several weeks.
