Propagation of Artemisia tridentata Nutt. ssp. bolanderi (Gray) Hall & Clements
Artemisia tridentata Nutt. ssp. bolanderi (Gray) Hall & Clements, commonly known as Bolander's sagebrush, can be propagated through both seed and vegetative methods.
Seed Propagation
Seeds of Bolander's sagebrush can be acquired by collecting ripe seeds from the parent plant in autumn or purchasing them from a reputable dealer. The seeds should be sown in a well-draining potting mix and covered lightly with soil. They should be kept moist and placed in a warm, sunny location.
Alternatively, the seeds can be stratified for 4-6 weeks in moist sand or vermiculite prior to planting to enhance germination rates. Once germinated, the seedlings should be transplanted into individual containers and grown until they are large enough to be transplanted into their final location.
Vegetative Propagation
Bolander's sagebrush can also be propagated through vegetative methods such as cuttings. Semi-hardwood cuttings can be taken from the parent plant in mid-summer, when the stems are partially matured but not fully lignified. The cuttings should be 4-6 inches long and have at least two leaf nodes.
The lower leaves should be removed, and the cuttings dipped in rooting hormone before being planted in a well-draining potting mix. They should be kept moist and placed in a shaded location until roots have formed, after which they can be transplanted into their final location.
