Propagation of Haplopappus bloomeri Gray var. ophitidis J.T. Howell
Haplopappus bloomeri Gray var. ophitidis J.T. Howell, commonly known as Snake River rabbitbrush, is a deciduous shrub that belongs to the Asteraceae family. The plant is native to the western United States and is mainly found in areas with well-draining soils in full sun or partial shade. One of the most popular methods of propagating Haplopappus bloomeri Gray var. ophitidis J.T. Howell is by seed, although cuttings can also be used.
Propagation by Seed
Propagation by seed is an easy and cost-effective way to grow several plants from one parent plant. The best time to collect seed is in the summer after the plant has finished blooming. The seeds should be mature and ready for harvest when the flowering heads turn brown and dry. Once collected, the seeds should be stored in a cool, dry, and dark place until ready for planting.
To plant the seeds, the soil should be prepared by loosening it up and removing any debris. The seeds can be either broadcast in place or sowed individually in pots. Once planted, the soil should be kept moist but not overly wet. Germination can take 10-14 days, after which the plants can be thinned to one plant every 12-18 inches.
Propagation by Cuttings
Propagation by cuttings can also be used to propagate Haplopappus bloomeri Gray var. ophitidis J.T. Howell. This method involves taking a cutting of the plant and rooting it in soil or water. The best time to take cuttings is in the fall when the plant is going into dormancy.
The cuttings should be taken from healthy, disease-free parent plants and should be at least four to six inches long. Once collected, the cuttings should be trimmed of any leaves or flowers and then dipped in rooting hormone. The cuttings can then be planted in a well-draining potting mix or a soilless mix. The soil should be kept moist, and the cuttings should be kept in a bright but shaded area. Roots should develop in 3-4 weeks, after which the plants can be transplanted into their permanent growing location.
