Xylorhiza tortifolia var. imberbis, also known as Mojave woody-aster, is a drought-tolerant perennial plant. It is native to the Mojave and Sonoran deserts in the Southwestern United States. Propagation of this plant can be achieved through several methods, including division, seed propagation, and stem cuttings.
Division
Division is the most straightforward method for propagating Xylorhiza tortifolia var. imberbis. The ideal time to divide the plant is in early spring or fall when the weather is mild, and there is less stress on the plant. To divide the plant, dig it out of the ground and wash away the soil from the roots. Use a sharp, sterile pair of scissors or a knife to cut the root ball into sections, ensuring that each section has several buds and a healthy root system. Transplant the divided sections into a well-draining soil mix and water them thoroughly. Keep the soil moist until new growth emerges.
Seed Propagation
Seed propagation is another method for propagating Xylorhiza tortifolia var. imberbis. The plant produces small, black, winged seeds in late summer. Collect the seeds before they disperse and sow them in a container filled with a well-draining soil mix. Cover the container with plastic wrap or a clear plastic bag to create a greenhouse effect and maintain moisture. Place the container in a bright location away from direct sunlight. Keep the soil moist until the seeds germinate, which can take 2-4 weeks. Once the seedlings have emerged, remove the plastic wrap or bag and place the container in a sunny location.
Stem Cuttings
Stem cuttings are another way to propagate Xylorhiza tortifolia var. imberbis. This method is most successful in the summer when the plant is producing new growth. Take a cutting from the tip of a stem that is at least 3 inches long and has several pairs of leaves. Remove the lower pairs of leaves, leaving only a few at the tip. Dip the cut end of the stem in rooting hormone and place it in a container filled with a well-draining soil mix. Cover the container with plastic wrap or a clear plastic bag to maintain moisture and place it in a bright location away from direct sunlight. Keep the soil moist until roots develop, which can take several weeks. Once the cutting has developed roots, remove the plastic wrap or bag and transplant the young plant into a larger container or the ground.
