Origin
Ericameria nauseosa (Pallas ex Pursh) Nesom & Baird ssp. nauseosa var. latisquamea (Gray) Nesom & Baird, commonly known as rubber rabbitbrush, is a native species found in western North America. It can be found in the Northern Rocky Mountains, Great Basin, and across the western United States, including in areas of Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming.
Common Names
Rubber rabbitbrush is also known as gray rabbitbrush or chamisa, but it is most commonly referred to by its scientific name.
Uses
Rubber rabbitbrush has many uses, both for animals and humans. It is an important food source for many wildlife species, including rabbits, elk, and deer during the winter months when other vegetation is scarce. It is also a preferred browse for livestock during the fall months.
Human uses for rubber rabbitbrush include traditional Native American medicinal uses for treating a variety of ailments, such as sore throats, stomach issues, and infections. The plant was also used by Native Americans to make baskets, brooms, and ceremonial items.
In addition, rubber rabbitbrush is an important plant for soil stabilization in disturbed areas, such as mines, roadsides, and construction sites. The dense root system of the plant helps to hold soil in place and prevent erosion.
General Appearance
Rubber rabbitbrush is a deciduous shrub that can grow up to six feet tall and ten feet wide. The plant has a woody stem and small, narrow leaves. In the fall months, the plant produces bright yellow flowers that cover the entire shrub, creating a beautiful display. The flowers are followed by white, fuzzy seed heads that persist throughout the winter months.
The plant prefers dry, sandy soils and can tolerate drought conditions. It is able to grow in a variety of habitats, including grasslands, deserts, and mountainous areas.
Growth conditions of Ericameria nauseosa subspecies nauseosa variety latisquamea
Ericameria nauseosa subspecies nauseosa variety latisquamea is a western North American plant species that prefers dry, sunny habitats. It is commonly found in grasslands, sagebrush plains, and subalpine meadows at elevations ranging from 2,000 to 11,000 feet.
Light Requirements
This species requires full sun for optimal growth. It can tolerate some shade but will not thrive if shaded for extended periods. In areas with hot summers, a little afternoon shade may benefit the plant.
Soil Requirements

Temperature Requirements
This species can tolerate a wide range of temperatures. It is drought-tolerant and can withstand high heat and periods of prolonged drought. However, it also grows well in areas with cold winters, and it can tolerate freezing temperatures.
In conclusion, Ericameria nauseosa subspecies nauseosa variety latisquamea, is a hardy plant that requires full sun, well-drained soil, and can tolerate a wide range of temperatures. It grows in many different types of soil, but the plant will not survive in waterlogged soil. Understanding these growth requirements can help gardeners and land managers cultivate a healthy population of Ericameria nauseosa ssp. nauseosa var. latisquamea to protect these plants and the ecosystems they inhabit.
Cultivation
Ericameria nauseosa var. latisquamea is a hardy plant that thrives in areas with full sunlight. It can tolerate a wide range of soil types, including sandy soils, loamy soils, and clay soils. The plant is drought-tolerant and can grow in areas with relatively low amounts of rainfall. This plant is typically propagated from seeds.
Watering Needs
Ericameria nauseosa var. latisquamea requires minimal watering once established. During the first year of growth, it may be necessary to provide regular watering to ensure proper establishment. After that, the plant can go extended periods without being watered. Water should be provided when the soil around the plant feels dry to the touch.
Fertilization
Ericameria nauseosa var. latisquamea does not require regular fertilization. However, if the plant appears weak or unhealthy, it can benefit from a balanced fertilizer applied in the early spring. It is important not to over-fertilize the plant, as this can lead to weak growth.
Pruning
Ericameria nauseosa var. latisquamea typically does not require pruning. However, to maintain a neat and tidy appearance, you can prune the plant in late winter or early spring. Any dead or damaged branches should be removed at this time. Light pruning can also be done to shape the plant if necessary.
Propagation of Ericameria nauseosa ssp. nauseosa var. latisquamea
Ericameria nauseosa ssp. nauseosa var. latisquamea, also known as rubber rabbitbrush, is a shrub that is native to western North America. It is commonly found in arid regions and can grow up to six feet tall.
Propagation of this plant can be done through several methods, which include seed propagation, stem cuttings, and division.
Seed Propagation
The seeds of Ericameria nauseosa ssp. nauseosa var. latisquamea can be collected in the fall and sown directly into the ground in the same season or in the spring. The soil should be well-draining and the seeds should be covered with a thin layer of soil. Water the soil regularly, but do not soak it. The seeds should germinate in one to two weeks.
Stem Cuttings
Another method of propagating this plant is through stem cuttings. Take a four to six-inch cutting of a stem in the summer and dip the cut end in rooting hormone. Plant the cutting in a pot filled with well-draining soil and keep it in a warm, bright location. Keep the soil moist and within two to four weeks, roots should begin to grow.
Division
Ericameria nauseosa ssp. nauseosa var. latisquamea can also be propagated through division. This method is best done in the spring. Dig up the plant and gently separate the root ball into smaller divisions. Plant the divisions in well-draining soil and keep the soil moist until new growth appears.
Propagation of Ericameria nauseosa ssp. nauseosa var. latisquamea can be done through several methods, each with its own advantages. Seed propagation and stem cuttings are relatively simple and do not require much equipment, while division can be a more intensive process. Whichever method you choose, make sure to choose healthy plants for the best results.
Disease and Pest Management of Ericameria nauseosa ssp. nauseosa var. latisquamea
Ericameria nauseosa ssp. nauseosa var. latisquamea, commonly known as rubber rabbitbrush, is a tough and hardy shrub that can tolerate harsh environmental conditions such as drought, poor soil, and extreme temperatures. However, like any plant, it can still fall prey to diseases and pests that can weaken or even kill it if left unchecked.
Common Pests
Some common pests that can affect rubber rabbitbrush include:
- Aphids: These tiny insects can infest the plant and suck the sap from its leaves and stems, causing stunted growth and distorted leaves. To manage aphids, try spraying the plant with a strong stream of water or using an insecticidal soap.
- Spider mites: These arachnids are very small and can build webs on the plant's leaves. They also suck the sap from the plant, causing stunted growth and yellowed leaves. To manage spider mites, try spraying the plant with a strong stream of water or using an insecticidal soap.
- Leafhoppers: These insects can cause yellowed leaves and stunted growth by sucking the sap from the plant. To manage leafhoppers, try using sticky yellow traps or applying an insecticide approved for garden use.
Common Diseases
Some common diseases that can affect rubber rabbitbrush include:
- Fungal diseases: Rubber rabbitbrush can be susceptible to various fungal diseases such as leaf spot, powdery mildew, and root rot. To manage fungal diseases, try removing any infected plant material and avoiding overhead watering. You can also try applying a fungicide approved for garden use.
- Viral diseases: Rubber rabbitbrush can be infected by various viruses, including mosaic virus and yellow dwarf. There is no cure for viral diseases, so it is best to remove infected plant material and practice good hygiene to prevent the spread of the virus.
Regular monitoring of your plants and quick action against any signs of pests or diseases can help keep your rubber rabbitbrush healthy and strong.
