Propagation of Draba sphaerocarpa J.F. Macbr. & Payson
Draba sphaerocarpa J.F. Macbr. & Payson is a small, perennial herbaceous plant commonly found in subalpine and alpine zones in Western North America. There are several methods for propagating Draba sphaerocarpa, including seed propagation, division, and cuttings.
Seed Propagation
Seed propagation is the most common method used to propagate Draba sphaerocarpa. The seeds should be collected when the seed pods are fully ripe and dry. The seeds should be sown in a well-draining soil mix that is moist but not wet. The seeds should be sown to a depth that is approximately equal to their diameter. The seedlings should be kept in a cool, shaded area until they are established and then they can be transplanted to their final location.
Division
Draba sphaerocarpa can also be propagated by division. This method involves digging up the plant and separating the clumps into individual plants. The separated plants should be replanted in a well-draining soil mix that is moist but not wet. The new plants should be cared for in the same manner as the seedlings.
Cuttings
Another method for propagating Draba sphaerocarpa is through stem cuttings. The stem cuttings should be taken from the plant during the summer months when the plant is actively growing. The cuttings should be approximately 3-4 inches in length and should be taken from healthy, disease-free plants. The cuttings should be planted in a well-draining soil mix that is moist but not wet. The cuttings should be kept in a cool, shaded area until they are established and then they can be transplanted to their final location.
