It is native to Mexico and prefers warm climates where the average temperature is around 70°F. The plant produces trumpet-shaped flowers that are purple and bloom during the summer and fall.
Propagation methods
Ruellia lorentziana Griseb. can be propagated through various methods including seeds, cuttings, and division of the root ball.
Seeds
Seeds can be sown either indoors or directly into the ground. For indoor sowing, the seeds should be sown in a mixture of equal parts of sand, peat, and perlite. The mixture should be kept moist until the seeds germinate. For direct sowing, the soil should be loosened and the seeds should be sown about a quarter-inch deep. The seeds should be kept moist until germination.
Cuttings
Stem cuttings can be taken from the plant during the active growth period. The cuttings should be around 6 inches long and should be taken from the tips of the plant. Remove the leaves from the lower half of the cutting and dip the cut end into a rooting hormone. Place the cutting in a pot filled with soilless potting mix and cover it with plastic to retain moisture and increase humidity.
Division of the root ball
Division of the root ball can be done in late winter or early spring. Dig up the plant and gently separate the roots into smaller sections. Each section should have at least one stem and a healthy root system. Replant the sections in well-draining soil and water thoroughly.
