Gardeners think of Hawaii when considering the ornamental plumeria. The flowering shrub or tree thrives in sunshine and does well in warm, dry regions. Its fragrant blossoms are popular when making flowered Hawaiian leis. New plants can grow from seeds, yet they don't necessarily mimic the parent plant's characteristics. Another way to start a new plumeria bush is to use a cutting taken from a parent plant. Start the cutting in the spring and the roots will develop in about three months and be ready to plant in the garden.
Measure the cutting, beginning at the bottom, to 4 inches and mark it with a pen.
Fill a pot with a mixture of two parts perlite to one part peat moss. Fill to about 1 inch from the rim.
Fill one paper cup with water and another with 2 to 3 inches of rooting hormone.
Dip the bottom of the cutting first into the cup of water, then into the rooting mix so that the bottom of the cutting is covered with rooting mix.
Insert the end covered with rooting mix deep enough into the soil that the marking you made in Step 1 is even with the rim of the pot.
Fill the pot up to the rim with gravel. The marking on the cutting should be level with the top of the pea gravel.
Add water slowly, until it begins to pour out of the bottom of the pot.
Set in a sunny location. Water again when the soil dries out.
