Propagation of Geum rossii (R. Br.) Ser. var. depressum (Greene) C.L. Hitchc.
Geum rossii (R. Br.) Ser. var. depressum (Greene) C.L. Hitchc., commonly known as Ross's avens, can be propagated using different methods. The plant can be propagated by seeds or vegetative means such as division and cuttings.
Propagation by seeds
Propagation by seeds is the most common method of propagating Geum rossii (R. Br.) Ser. var. depressum (Greene) C.L. Hitchc. Seed propagation can be done in fall or early spring. Seeds should be collected when they are ripe and then stratified at low temperatures for one to two months.
After stratification, the seeds should be sown on a seedbed. The soil should be well-draining and moist. Seeds should be covered with a thin layer of soil and kept moist. Germination usually occurs within two to six weeks.
Division
Propagation by division is another method of propagating Geum rossii (R. Br.) Ser. var. depressum (Greene) C.L. Hitchc. This method is suitable for mature plants. Division should be done in spring or fall.
To divide the plant, carefully dig up the clump and separate it into smaller sections. Each section should have several shoots and a healthy root system. Replant the divisions in well-prepared soil and water thoroughly.
Cuttings
Propagation by cuttings is also possible with Geum rossii (R. Br.) Ser. var. depressum (Greene) C.L. Hitchc. This method is usually used to propagate cultivars. Stem cuttings should be taken in spring or early summer.
To make a cutting, select a healthy stem and make a clean cut just below a node. Remove the leaves from the lower part of the stem and dip the cut end in rooting hormone. Plant the cutting in well-prepared, moist soil and keep it in a bright, shaded area until it roots.
