Leiocarpa (Payson & St. John) C.L. Hitchc.
Draba aurea Vahl ex Hornem. var. leiocarpa (Payson & St. John) C.L. Hitchc. can be propagated through different methods, including seeds, cuttings, and division.
Propagation by Seeds
Propagation by seeds is the most common way to propagate Draba aurea Vahl ex Hornem. var. leiocarpa (Payson & St. John) C.L. Hitchc. Seeds should be collected when the pods turn brown and the seeds can be easily shaken out. The collected seeds should be sown in sterile, well-draining soil.

Propagation by Cuttings
Propagation by cuttings can also be done with Draba aurea Vahl ex Hornem. var. leiocarpa (Payson & St. John) C.L. Hitchc. Stem cuttings can be taken in late spring or early summer, using a sharp, sterile knife. The cuttings should be about 5 to 10 cm in length and have at least one set of healthy leaves. The lower leaves should be removed, and the cuttings should be treated with a rooting hormone. The cuttings should be planted in well-draining soil and kept moist. The cuttings should be placed in a warm and bright location but should be protected from direct sunlight.
Propagation by Division
Propagation by division can also be done with Draba aurea Vahl ex Hornem. var. leiocarpa (Payson & St. John) C.L. Hitchc. This method involves dividing the plant at its base into two or more sections, each with its own roots and foliage. Division is best done in early spring, before new growth appears. The divided sections should be planted in well-draining soil and kept moist until new growth appears.
