Propagation of Fremontia Californica Torr. Var. Typica M. Harvey
Fremontia Californica Torr. var. Typica M. Harvey, also known as California flannel bush, is a shrub native to California and Baja California. It is a hardy plant that can grow 15 to 20 feet tall and wide. Propagation of this plant can be done through several methods:
Seed Propagation
Fremontia Californica can be propagated from seeds. Collect the seeds in summer, store them cool and dry conditions, and sow them in early spring. The seeds need a cold stratification period of 4 to 8 weeks, after which they can be germinated at temperatures between 70°F to 80°F. Sow the seeds in well-draining soil mix and lightly cover them with soil mix or sand. Keep the soil moist and place the container in a bright location, but not under direct sunlight. Seedlings take 2 to 3 months to germinate and should be transplanted to a larger container or outdoors when they are large enough to handle.
Softwood Cuttings
Fremontia Californica can also be propagated from softwood cuttings. Take 3- to 6-inch cuttings from new growth that is not yet woody and remove all leaves except for the topmost one or two. Dip the cuttings in rooting hormone and place them in a well-draining soil mix or a mix of peat and perlite. Keep the soil moist and place the container in a bright location, but not under direct sunlight. Cover the container with clear plastic to create a greenhouse-like environment. Once the cuttings develop roots, transfer them to a larger container or outdoors in a well-draining location.
Hardwood Cuttings
Propagation of Fremontia Californica from hardwood cuttings is also possible. In late fall or early winter, take 6- to 9-inch long cuttings from the previous year's growth that are woody and have no foliage. Make a clean cut at the base using a sharp knife and dip the cuttings in rooting hormone. Place the cuttings in well-draining soil mix or a mix of peat and perlite. Keep the soil moist and place the container in a bright location, but not under direct sunlight. Cover the container with clear plastic to create a greenhouse-like environment. Once the cuttings develop roots, transfer them to a larger container or outdoors in a well-draining location.
