Propagation of Pycnocoma parviflora Pax
Pycnocoma parviflora Pax, commonly known as small-flowered pycnocoma, is a perennial herb that belongs to the Asteraceae family. It is native to California and can be propagated both by seeds and cuttings.
Propagation by Seeds
The seeds of Pycnocoma parviflora Pax can be easily collected from the plant after the flowering season. The collected seeds should be thoroughly cleaned to remove any debris or chaff and stored in a cool and dry place until sowing time.
The best time to sow the seeds is in the fall season, as the plants require a chilling period to germinate. The seeds can be sown in seed trays filled with well-draining soil mix. The seeds should be lightly covered with soil and kept moist until germination.
The germination of Pycnocoma parviflora Pax seeds generally takes about 2-3 weeks, and the young seedlings should be transplanted to individual pots as soon as they become large enough to handle. The plants can be planted in their permanent location in the garden after they have established their roots.
Propagation by Cuttings
Pycnocoma parviflora Pax can also be propagated through stem cuttings, although this method is not preferred over seed propagation. The stem cutting should be taken from a healthy parent plant in the spring or early summer season.
The cutting should be about 4-6 inches long and should be taken from a non-flowering stem. The lower leaves of the cutting should be removed, and the remaining leaves should be cut in half to reduce the water loss from the cutting.
The cutting should be dipped in rooting hormone and planted in a well-draining soil mix. The soil should be kept moist, and the cutting should be placed in a bright but shaded location. The cutting will develop roots in about 6-8 weeks, and the young plant can be transplanted to its permanent location in the garden.
