It typically grows in dry, rocky soils, and is tolerant of high heat and drought.
Common Names and Uses
Dicoria canescens Gray ssp. wetherillii is commonly known as white tackstem or Wetherill's tackstem. This plant is known for its medicinal properties where it has been used traditionally by Native Americans for its healing properties in treating various conditions such as sore throats, stomachaches, and skin ailments. Moreover, some Native American groups consume this plant as a tea for its soothing properties.
General Appearance
Dicoria canescens Gray ssp. wetherillii is a low-growing, perennial shrub that typically grows to a height of 5-20 centimeters. The plant has rigid stems that are covered in a dense layer of fine hairs, giving it a grayish appearance. The leaves of the plant are small, narrow, and covered in fine hairs, which also contributes to the grayish appearance of the plant. During the blooming season, the plant produces small, white flowers that are clustered together at the ends of the stems. The plant has small, prickly fruit that are covered in hooked spines.
Light Requirements
Dicoria canescens Gray ssp. wetherillii (Eastw.) Kartesz, comb. nov. ined. prefers full sun exposure for optimal growth and reproduction. The plant can tolerate some shade, but it may result in reduced growth and delay in flowering. Therefore, it is best to plant the species in an area with direct and continuous sunlight.
Temperature Requirements
The species is adapted to grow in the arid and semi-arid regions of North America. Dicoria canescens Gray ssp. wetherillii (Eastw.) Kartesz, comb. nov. ined. can tolerate extreme heat and drought conditions, making it an ideal plant for xeriscaping. The average temperature range for the plant's growth is 10°C to 30°C. However, the plant can also tolerate temperatures as low as -20°C.
Soil Requirements
Dicoria canescens Gray ssp. wetherillii (Eastw.) Kartesz, comb. nov. ined. grows best in well-draining and sandy soils that are rich in minerals. The plant can also tolerate rocky and gravelly soils, as long as they have good drainage. It is essential to avoid planting the species in heavy clay soils that retain water for extended periods since this can lead to root rot and eventual death of the plant.
Cultivation methods for Dicoria canescens Gray ssp. wetherillii (Eastw.) Kartesz, comb. nov. ined.
Dicoria canescens Gray ssp. wetherillii (Eastw.) Kartesz, comb. nov. ined. is a hardy plant that grows well in a range of soil types. It prefers well-draining soils with a pH of 6.0 to 7.0. The plant is tolerant of drought conditions and can grow in areas with low rainfall. It prefers full sun but can tolerate some shade, especially in hot climates.
Watering needs for Dicoria canescens Gray ssp. wetherillii (Eastw.) Kartesz, comb. nov. ined.
While the plant is drought-tolerant, it still requires regular watering. In the first few months after planting, water the plant every two to three days. Once the plant is established, reduce watering to once a week. Be sure to water deeply to promote healthy root growth.
Fertilization for Dicoria canescens Gray ssp. wetherillii (Eastw.) Kartesz, comb. nov. ined.
This plant does not require regular fertilization. If you choose to fertilize, use a balanced fertilizer in early spring. Avoid fertilizing during the hot summer months as this can damage the plant.
Pruning Dicoria canescens Gray ssp. wetherillii (Eastw.) Kartesz, comb. nov. ined.
Pruning this plant is not necessary, but you can pinch back new growth to promote a fuller, bushier plant. If the plant becomes leggy, it may be cut back to promote new growth. Do this in early spring before new growth emerges.
Propagation of Dicoria canescens Gray ssp. wetherillii (Eastw.) Kartesz, comb. nov. ined.
Dicoria canescens Gray ssp. wetherillii (Eastw.) Kartesz, comb. nov. ined. is commonly known as Wetherill's dicoria and belongs to the family Asteraceae. This plant is native to North America and is commonly found in the deserts of the southwestern United States. Wetherill's dicoria can be propagated through several methods as explained below.
Seed Propagation
Seed propagation is the most common and effective way of propagating Dicoria canescens Gray ssp. wetherillii. The seeds of this plant can be collected from the mature flower stalks during the late summer months. After collecting the seeds, they should be dried and stored in a cool and dry place until planting time. The best time to plant the seeds is in the early spring months when the soil temperature is warm enough to promote germination.
The seeds should be sown onto well-draining soil, barely covered, and watered gently until the seedlings emerge. It is important to keep the seedlings moist but not water-logged. Once the seedlings have grown big enough, they can be transplanted to their permanent location.
Division Propagation
Dicoria canescens Gray ssp. wetherillii can also be propagated through division. This method involves dividing the root clump of the plant into several sections and planting each section separately.
The best time to do division propagation is during the early spring months when new growth is beginning to emerge. The clump should be carefully dug up, dividing the rootball into smaller sections, each with a shoot and some roots. These sections can then be replanted into well-draining soil and watered gently.
Cuttings Propagation
Cuttings are another way to propagate Wetherill's dicoria. This method is not as reliable as seed or division propagation, but it can be used if the other methods are not available. Cuttings should be taken in the early spring months when new growth is beginning to emerge.
The cuttings should be taken from the tips of the stems and should be about 3-4 inches in length. Remove the leaves from the bottom half of the cutting and dip the cut end in rooting hormone. Place the cutting into well-draining soil and keep it moist but not water-logged. With time, the cutting will start to root and grow into a new plant.
Overall, Dicoria canescens Gray ssp. wetherillii can be propagated through several methods including seed, division, and cuttings. Each of these methods has its advantages, and the choice of method will depend on the purpose and availability of plant material.
