Propagation of Sidalcea malviflora (DC.) Gray ex Benth. ssp. sparsifolia C.L. Hitchc. var. sparsifolia
Sidalcea malviflora (DC.) Gray ex Benth. ssp. sparsifolia C.L. Hitchc. var. sparsifolia can be propagated through a variety of methods, some of which include:
Seed Propagation
The easiest method of propagating Sidalcea malviflora (DC.) Gray ex Benth. ssp. sparsifolia C.L. Hitchc. var. sparsifolia is through seed propagation. The plant can be grown from seed, which should be sown in the fall or early spring. Sow the seeds directly into the soil in a prepared bed, spacing them about 12 inches apart. Cover the seeds lightly with soil, water them well, and keep the area moist until germination. Germination usually occurs within two to four weeks.
Division
Sidalcea malviflora (DC.) Gray ex Benth. ssp. sparsifolia C.L. Hitchc. var. sparsifolia can also be propagated through division. Divide the plant in the spring or fall, making sure that each new division has both roots and shoots. Transplant the divisions into prepared soil, spacing them about 12-18 inches apart.
Cuttings
Another method of propagating Sidalcea malviflora (DC.) Gray ex Benth. ssp. sparsifolia C.L. Hitchc. var. sparsifolia is through cuttings. Cuttings should be taken in early summer when stems are still green and semi-soft. Cut a 3-4 inch section of stem below a node, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cutting in soil, mist the plant, and cover it with a plastic bag to create a humid environment. Keep the soil moist until roots form, which usually takes about six to eight weeks. Once the plant has established roots, it can be transplanted into a prepared bed.
