Propagation of Chrysothamnus viscidiflorus var. lanceolatus
Chrysothamnus viscidiflorus var. lanceolatus, commonly referred to as Lanceleaf Rabbitbrush, is a shrub native to the western region of North America. The plant is a popular choice for reclamation projects in the southern plains and western regions. Propagation is an important aspect of cultivating the plant, and there are a few methods available for propagating Lanceleaf Rabbitbrush.
Seed Propagation
Seed propagation is one of the most common ways to propagate Lanceleaf Rabbitbrush. The plant produces plenty of seeds that are easy to collect. The best time to collect seeds is in late summer or fall, once the seeds have fully matured. Seeds can be harvested by cutting stems with seed heads, placing them in a paper bag, and shaking them to dislodge the seeds. Once harvested, the seeds can be planted directly into the ground or in containers filled with well-draining soil. They should be watered regularly until germination, which usually takes a few weeks.
Cutting Propagation
Another way to propagate Lanceleaf Rabbitbrush is through cuttings. Cuttings are taken from healthy parent plants during the growing season and rooted in well-draining soil. The best time to take cuttings is in the early to mid-summer, during the plant's active growing season. Cuttings should be about 6 inches long and taken from semi-hardwood stems. The leaves on the lower half of the cuttings should be removed, and the cuttings should be planted in a mixture of sand and peat moss. The cuttings should be kept moist and protected from direct sunlight until roots develop, which usually takes a few weeks.
Division Propagation
Last but not least, Lanceleaf Rabbitbrush can also be propagated through division. This method involves digging up a mature plant and dividing it into two or more sections using a sharp knife. Each section should have some healthy roots and a few stems with leaves. The divisions should be replanted into well-draining soil and kept moist until they become established. Division propagation is best done in the spring or early fall when the plant is not actively growing.
