Propagation of Eriogonum ericifolium Torr. & Gray var. thornei Reveal & Henrickson
Eriogonum ericifolium Torr. & Gray var. thornei Reveal & Henrickson, commonly known as Thorne's buckwheat, is a rare shrub that is native to the southwestern region of the United States. Propagation of Thorne's buckwheat can be challenging due to its slow growth rate, limited seed production, and strict environmental requirements.
Seed Propagation
Thorne's buckwheat can be propagated by seed, but the process requires patience and attention to detail. The seeds need to be collected when they are ripe, which usually occurs in the late summer or early fall. The collected seeds should be dried and stored in a cool, dry place until ready to plant.
Before planting, the seeds should be treated with a dilute sulfuric acid solution to improve germination rates. Once treated, the seeds can be planted in well-drained soil and kept moist until germination occurs, which can take anywhere from several weeks to several months. The seedlings should be transplanted to individual containers once they are large enough to handle, and they should be grown in a greenhouse or under shade until they are large enough to be planted in their permanent location.
Cuttings Propagation
Another method of propagating Thorne's buckwheat is through stem cuttings. The best time to take cuttings is in the late summer or early fall, when the plant has finished flowering. The cuttings should be taken from the current year's growth and should be about 4-6 inches long.
The cuttings should be treated with a rooting hormone and then planted in a well-drained soil mixture. They should be kept moist and covered with a plastic dome or placed in a propagator to maintain humidity. After a few weeks, the cuttings should begin to form roots and can be transplanted to individual containers. The rooted cuttings should be grown in a greenhouse or under shade until they are large enough to be planted in their permanent location.
Division Propagation
Thorne's buckwheat can also be propagated through division, but this method should be used with caution as the plant does not respond well to transplanting. The best time to divide the plant is in the early spring, before it begins to produce new growth. The plant should be carefully dug up and divided into smaller sections, making sure each section has some roots attached.
The divided sections should be planted in well-drained soil and kept moist until established. It is important to note that Thorne's buckwheat has a taproot, so it may take some time for the plant to recover from the division and establish a new root system.
