Lantana plants are a flowering, tropical perennial native to the tropical regions of the Americas. This low-growing shrub attracts butterflies to the garden with its bright, colorful flowers. Plant lantana in full-sun and well-draining soil. Though hardy in stressed conditions and drought, lantana flowers best when watered weekly. Lantana is in the family Verbenaceae, a large plant family with more than 150 species, according to Texas A&M University. The herbaceous stem cuttings of the lantana plant root easily, making this the preferred method of propagation.
Fill a 2-inch pot with a damp mixture of equal parts vermiculite and peat moss. Alternative planting mediums include coarse sand, perlite or a perlite and peat mixture. If you are staring several cuttings, fill an 8- or 10-inch pot with the rooting medium and put all the cuttings together.
Take cuttings from a healthy lantana plant. Select a new, green shoot and measure about 4 to 6 inches down from the tip of the shoot. Make a clean cut at a 45-degree angle just below a leaf node (the place where a leaf attaches to the branch). Use clean, sharp pruning shears to avoid transferring disease or damaging the cutting.
Pinch off all of the bottom leaves, leaving only two or three leaves at the tip of the cutting. Roll the cut end of the lantana cutting in hormone rooting powder or liquid hormone rooting compound.
Slide the bottom 2 inches of the cutting into the pot filled with rooting material. Press down gently around the cutting to secure it in the pot. Space multiple cuttings 2 to 3 inches apart in the pot. Mist the cutting leaves with clean, cool, water.
Slide a clear plastic bag upside down over the lip of the pot. Secure the plastic bag with a rubber band or twist tie. Drive a 8-inch stick or dowel into the center of the pot before putting the bag on, to keep the plastic from touching or falling on the leaves.
Place the pot in a warm room away from direct sunlight. Keep the cutting between 70 and 80 degrees F to stimulate root formation. Remove the plastic bag every three to four days and feel the soil mixture. When it feels slightly dry, add water until the medium is damp. Replace the plastic bag around the lantana cuttings to maintain a humid environment.
Give the cutting a gentle tug after two weeks. If there is resistance, rooting is taking place. Gently remove the lantana cutting from the propagation pot and check the root development after the fourth week. When the roots are 1 inch long, transplant the cuttings into individual 6-inch pots filled with potting soil.
