The stem will start developing roots within two to three weeks, and new growth will emerge from the top of the stem.
Division Propagation
Division propagation is another method you can use to propagate Downingia yina Applegate. The best time to divide the plant is in the fall when the plant has gone dormant. Dig up the entire plant and divide it into smaller sections, making sure that each division has a healthy root system.
