While not widely used in traditional medicine or as a food source, some Indigenous peoples in the western United States have used the plant for medicinal purposes, such as treating respiratory infections and digestive issues. However, the plant is primarily used for its ornamental qualities, particularly its unique foliage and showy flowers.
General Appearance
Eriogonum deflexum Torr. ssp. insigne (S. Wats.) S. Stokes is a low-growing, sprawling perennial plant that typically reaches heights of 6 to 12 inches. Its leaves are grayish-green and wavy-edged, giving the plant its common name of Wavy-leafed Buckwheat. The plant's flowers are small and pink, and are arranged in dense clusters at the ends of the stems. The blooms typically appear from early summer through early fall, attracting a wide variety of pollinators.
Light Requirements
Eriogonum deflexum Torr. ssp. insigne (S. Wats.) S. Stokes is typically found in full sun or bright light conditions. It thrives in open, exposed areas like rocky slopes or open meadows.
Temperature Requirements
Eriogonum deflexum Torr. ssp. insigne (S. Wats.) S. Stokes is native to areas with a dry, continental climate. It can tolerate hot temperatures in the summer and cold temperatures in the winter. However, it cannot withstand prolonged periods of freezing temperatures.
Soil Requirements
Eriogonum deflexum Torr. ssp. insigne (S. Wats.) S. Stokes prefers well-draining, sandy soil. It can grow in nutrient-poor soil and is often found in areas with rocky soil. However, it does not tolerate wet or poorly drained soils.
Cultivation Methods
Eriogonum deflexum Torr. ssp. insigne (S. Wats.) S. Stokes is a beautiful plant that is known to grow well in rocky or sandy soils. It prefers dry and well-drained soils and full sun to semi-shade environments. It can withstand hot and dry climates but requires occasional watering during long dry spells.
The plant can be propagated by seed or cuttings. If you are propagating from seeds, the best time to sow is in fall. You can sow the seeds in a mixture of sand, peat, and perlite. It is important to keep the seeds moist and warm. They will take about two weeks to germinate. Once they have grown to a size of 5-6 inches, you can transplant them into the final growing environment.
Watering Needs
Like most plants, Eriogonum deflexum requires some watering, especially during the first few weeks after planting. It is important to avoid overwatering as this plant thrives in drier environments. We recommend watering once a week or every ten days, depending on the level of moisture in the soil.
If you are unsure of when to water, you can use a soil moisture meter to check the soil's moisture level. The moisture requirement reduces during winter. Reduce watering frequency if the plant is grown in a more shaded area as plants grown in shaded areas require less water to survive.
Fertilization
Eriogonum deflexum is not a heavy feeder. It is adapted to low fertility soils, and applying fertilizer can actually harm the plant. Therefore, refrain from applying chemical fertilizers as they can affect the plant's growth and development.
Instead, the plant can benefit from mulching. Mulching provides shade for the roots, conserves water, and prevents soil erosion. Alternatively, use compost or leaf mould to add nutrients to the soil. This way, the plant receives the necessary growth nutrients without harming the plant's natural adaptation to low nutrients. Ensure you add only sufficient amounts that will not alter the plant's main growth habits.
Pruning
Eriogonum deflexum Torr. ssp. insigne (S. Wats.) S. Stokes can be pruned to maintain its shape after blooming. Late winter when there is no longer a risk for frost is the ideal period for pruning. Use a sterile pruning shear to lace or remove the dead or dying leaves, stems, or flowers.
You can either cut back the plant to a desired height, or selectively cut back only the limbs that have finished blooming the previous year. Avoid pruning during the hot weather seasons as this would cause stress on the plant.
Propagation Methods for Eriogonum deflexum Torr. ssp. insigne (S. Wats.) S. Stokes
Eriogonum deflexum Torr. ssp. insigne (S. Wats.) S. Stokes, commonly known as Spreading Buckwheat, is a hardy and low-growing plant that is native to California and Nevada. It is a popular choice for landscaping projects due to its attractive silvery-gray leaves and showy yellow flowers. Propagation of Eriogonum deflexum Torr. ssp. insigne can be done through various methods, including seeds, stem cuttings, and division.
Seeds
The easiest and most common propagation method for Eriogonum deflexum Torr. ssp. insigne is through seeds. Seeds are readily available from nurseries or can be collected from the plant in the fall. The seeds are small and can be sown directly into the soil where they are expected to grow. Make sure to choose a location with well-drained soil and full sun exposure. Seeds will germinate in the spring and the plant will begin to grow. While seeds are easy to germinate, a drawback is that it may take longer for the plant to mature, and it may be more difficult to ensure the resulting plant is identical to the parent plant.
Stem Cuttings
Eriogonum deflexum Torr. ssp. insigne can also be propagated by stem cuttings, though this method is slightly more challenging than using seeds. Cuttings, taken in the summer, should be about 4-6 inches long and include at least two nodes. Remove the leaves from the bottom half of the stem, dip the cut end in rooting hormone, and plant in well-drained, moist soil. Keep the soil moist and the cutting in a humid environment. If the cutting takes root, new growth should start within a few weeks. A potential drawback of this method is that it requires more care and attention than spreading seeds.
Division
The most difficult, but effective way to propagate Eriogonum deflexum Torr. ssp. insigne is by division. This method involves separating the plant into several sections and planting them separately. This method should be performed in the spring when the plant is actively growing. Dig around the plant's drip line and remove it from the soil. Gently separate the roots into several sections, each with its own set of stems and leaves. Make sure each section is large enough to survive on its own and replant. Tamp soil around the plant and water it well. Keep it moist until new growth appears. Division is an effective method but requires care, attention, and knowledge about the plant's root system to avoid damage.
With any of these propagation methods, it is important to make sure your plant is healthy and vigorous before attempting to propagate it. By using these methods, gardeners can ensure they will have a steady supply of the beautiful Eriogonum deflexum Torr. ssp. insigne in their gardens for years to come.
