Wats. ssp. purpusii grows naturally in stony soils derived from granite and volcanic rocks. A pH range of 6.5 to 7.5 is ideal for its growth, but the plant can tolerate soils that are slightly acidic or alkaline. It is best to avoid planting this species in heavy clay soils as they retain too much moisture, which can cause root rot.
Cultivation Methods:
Eriogonum kennedyi Porter ex S. Wats. ssp. purpusii (Brandeg.) Munz is a low-growing herb that thrives in full sun and well-drained soil. It requires a warm and dry climate, with temperatures ranging from 60-90°F. The plant grows well in rocky and sandy soil, and it is resistant to drought and frost.
Watering Needs:
The plant does not require frequent watering once it is established. It is best to water it deeply instead of frequently, preferably once a week in the summertime and twice a month in the cooler months. Over-watering can lead to root rot, so make sure the soil is dry before watering.
Fertilization:
Eriogonum kennedyi Porter ex S. Wats. ssp. purpusii (Brandeg.) Munz is a low-maintenance plant that does not require frequent fertilization. Apply a slow-release fertilizer once or twice a year, preferably during the growing season. Avoid high-nitrogen fertilizers, as they promote foliage growth but can hinder the development of flowers.
Pruning:
The plant does not require frequent pruning, but it can benefit from some light pruning after flowering. Prune back any dead or damaged stems and remove any spent flowers. This can help promote bushier growth and keep the plant looking neat and tidy.
Propagation of Eriogonum kennedyi Porter ex S. Wats. ssp. purpusii (Brandeg.) Munz
Eriogonum kennedyi Porter ex S. Wats. ssp. purpusii (Brandeg.) Munz, commonly known as Purpus' buckwheat, is a low-growing, shrubby perennial plant that is native to the southwestern United States. As an attractive landscape plant, it is often propagated by various methods, including seeds, cuttings, and division of clumps.
Propagation by Seeds
Propagation of Eriogonum kennedyi Porter ex S. Wats. ssp. purpusii by seeds is a simple and effective method. The seeds can be collected in autumn or winter when the seed capsules are fully ripe and dried. Once collected, the seeds should be stored in a cool, dry place until ready for use in spring.
Before sowing, the seeds should be stratified in the refrigerator for about six to eight weeks, which helps to break seed dormancy. The seeds can then be sown in a well-draining potting mix, pressed lightly into the soil surface, and then watered gently. The pots should be kept under light shade until germination, which typically occurs within two to three weeks.
Propagation by Cuttings
Eriogonum kennedyi Porter ex S. Wats. ssp. purpusii can also be propagated through stem cuttings. Select stem cuttings from the current season's growth in spring or early summer and make them about 3-4 inches long. Remove the lower leaves of the cutting and dip the cut end in rooting hormone to promote root development.
Prepare a rooting medium consisting of sand and perlite and insert the cutting about an inch deep into the medium. Water the tray and cover it with a clear plastic bag to maintain the humidity. Place the tray in a semi-shaded area and maintain the moisture level in the rooting medium by misting the cuttings daily. Rooting typically takes place within three to four weeks.
Propagation by Division of Clumps
Eriogonum kennedyi Porter ex S. Wats. ssp. purpusii can also be propagated by division of clumps. This method is best used in fall or early spring when the plant is dormant and is a good method for rejuvenating older clumps.
The plant should be lifted from the ground and the root ball gently separated into smaller sections. Each section should have some roots and several shoots. Plant the sections at the same depth as the original plant, water thoroughly, and keep the soil moist until new growth appears.
