Propagation of Machaeranthera pinnatifida (Hook.) Shinners ssp. gooddingii (A. Nels.) B.L. Turner & Hartman var. paradoxa B.L. Turner & Hartman
Machaeranthera pinnatifida (Hook.) Shinners ssp. gooddingii (A. Nels.) B.L. Turner & Hartman var. paradoxa B.L. Turner & Hartman, commonly known as Goodding's aster, can be propagated by seeds or cuttings.
Propagation by Seeds
To propagate Goodding's aster by seeds, collect the ripe seeds in late summer or early fall. The seeds can be directly sown in the garden or started indoors. If starting indoors, sow the seeds in seed trays filled with a well-draining potting mix. Keep the soil moist and at a temperature of around 70°F. The seeds should germinate in 1-2 weeks. Once the seedlings have 2-3 true leaves, transplant them into individual pots and grow them until they are large enough to be planted in the garden.
Propagation by Cuttings
Goodding's aster can also be propagated by stem cuttings. Take stem cuttings in early summer, when the plant is actively growing. Cuttings should be 3-4 inches long and should have at least two sets of leaves. Dip the cut end of the stem in rooting hormone and plant it in a well-draining potting mix. Keep the soil moist and the cutting in a bright, but not direct, light. The cutting should root in 2-3 weeks. Once the cutting has rooted, transplant it into a larger pot or directly into the garden.
