Pot or containers
Paper towel or paper plate
Sand and peat or peat and perlite
Angel trumpet, or Brugmansia suaveolens, is an exotic-looking plant featuring large blooms around 12 inches long that resemble trumpets. The blossoms open at night, release a strong, sweet aroma and close again with the morning sun. This small, semi-woody tree or shrub can reach mature heights ranging from 6 to 15 feet and grows best in USDA hardiness zones 10 to 12 outside or in other zones as a perennial or container plant. Propagate angel trumpet cuttings to grow more of these magnificent beauties.
Get the angel trumpet cuttings in the summer during the growing season. Obtain the cuttings in the early morning hours using a sharp knife or pruning shears. Cut a 6-inch section of a healthy branch that includes a small part of the older wood at the bottom. This is a "heel cutting." Collect more angel trumpet cuttings than needed to ensure enough grow.

Cut off any leaves on the bottom one-third to one-half of the cutting. Pour a small amount of the rooting hormone on a paper towel. Dip the end of the angel trumpet cutting into the hormone. Shake off any extra hormone. Discard any remaining hormone when finished to avoid contamination.
Fill a pot or container that has drainage holes with a mixture containing half sand and peat or half peat and perlite (or other well-draining soilless growing medium). Make holes 2 to 3 inches deep and the same diameter of the cuttings. Space the holes far enough apart for light to reach each leaf.
Place a cutting in each hole. Firm the soil around the cuttings to hold them erect. Saturate the growing medium with water to settle it around the cuttings. Cover the entire container with plastic to hold the moisture in. Place the angel trumpet cuttings in a location with indirect light. Mist the cuttings daily with a spray bottle to keep the soil moist.
Check the angel trumpet cuttings periodically to see if they are rooting by pulling on them gently. Roots are forming when the cuttings resist.
According to the Floridata website, all parts of the angel trumpet are narcotic and poisonous.
