Propagation of Balsamorhiza macrolepis Sharp var. macrolepis
Balsamorhiza macrolepis Sharp var. macrolepis, commonly known as bush sunflower, is a herbaceous plant native to North America. This plant is an excellent choice for gardens, landscapes, and wildscapes. It can be propagated through different methods, including seeds, cuttings, division, and root cuttings.
Propagation by seeds
Propagation by seeds is the most common method used to propagate Balsamorhiza macrolepis Sharp var. macrolepis. Collect mature seeds from the plant in autumn and store them in a cool and dry place. You can also buy seeds from a reliable source. Sow the seeds in well-draining soil in spring, at a depth of 1/8 inch. Keep the soil moist and warm, and the seeds will germinate within 14 to 21 days. Transplant the seedlings to their permanent location after they are well-established.
Propagation by cuttings
Balsamorhiza macrolepis Sharp var. macrolepis can also be propagated through stem cuttings. Take cuttings from the plant in late spring or early summer, when the plant is actively growing. Cut a 4 to the 6-inch-long stem from the top of the plant, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cutting in well-draining soil, keep it moist, and provide it with bright indirect light. The cutting will root within 2 to 4 weeks and can be transplanted to its permanent location.
Propagation by division
Propagation by division is a straightforward method to propagate Balsamorhiza macrolepis Sharp var. macrolepis. Divide the plant in spring or fall, when the plant is dormant or semi-dormant. Dig up the plant and gently separate the roots, making sure each division has some roots and leaves. Replant the divisions in well-draining soil, water thoroughly, and keep the soil moist until the plant is well-established.
Propagation by root cuttings
Propagation by root cuttings is another method to propagate Balsamorhiza macrolepis Sharp var. macrolepis. In early spring, dig up the plant, remove some roots, and cut them into 2 to 3 inches long sections. Plant the root cuttings upright in well-draining soil, at a depth of 1/2 inch. Keep the soil moist and warm, and the root cuttings will develop new shoots within a few weeks.
