Propagation of Silene scouleri Hook. ssp. pringlei (S. Wats.) C.L. Hitchc. & Maguire var. concolor (Greene) C.L. Hitchc. & Maguire
Silene scouleri Hook. ssp. pringlei (S. Wats.) C.L. Hitchc. & Maguire var. concolor (Greene) C.L. Hitchc. & Maguire can be propagated using both seeds and vegetative methods.
Propagation by Seeds
The seeds of Silene scouleri var. concolor can be sown directly into the soil during the fall or early spring seasons. The seeds should be surface-sown onto a well-draining soil mix that has been tamped down to ensure good seed-to-soil contact. Once the seeds are sown, water them gently to moisten the soil. Keep the soil evenly moist until the seedlings emerge. Thin the seedlings to their desired spacing once they have their true leaves.
Propagation by Cuttings
Silene scouleri var. concolor can also be propagated from stem cuttings. Take 4-6 inch long stem cuttings in the spring or early summer. Remove the lower leaves, and dip the cut end into rooting hormone. Stick the cuttings into a well-draining soil mix, and keep the soil evenly moist. After a few weeks, roots should start to form and new growth should emerge. Keep the newly rooted plants in a protected area for a few weeks before transplanting them into their final location.
