Origin
Ericameria viscidiflora (Hook.) L.C. Anders. ssp. puberula (D.C. Eat.) L.C. Anders. is a plant species that is native to North America. It can be found in the southwestern United States and northern Mexico.
Common Names
The Ericameria viscidiflora is commonly known as the Sticky goldenbush, brea or black brea in English and chamizo pegajoso in Spanish.
Uses
The Sticky goldenbush has several traditional medicinal uses, including using the leaves to treat headaches and body aches. It is also used for stomach problems and as a cold remedy. One of the most significant uses of this plant is that it is considered a pioneer species and can be used for land reclamation in disturbed areas.
General Appearance
The Ericameria viscidiflora is a shrub that can grow up to five feet tall and three feet wide. It has a woody stem and branches that are covered in sticky resin. The leaves are narrow, linear, and less than an inch long. The plant produces small yellow flowers that are about a quarter of an inch in diameter. The flowers bloom between August and November. The plant has a distinct resinous odor that can be detected from afar.
Light requirements:
Ericameria viscidiflora ssp. puberula typically grows in areas with full sun exposure. It requires at least six hours of direct sunlight each day to grow and thrive.
Temperature requirements:
This plant is native to the western United States and grows best in regions with hot, dry summers and cool winters. It can tolerate temperatures as low as -20 degrees Fahrenheit (-29 degrees Celsius) but prefers temperatures ranging from 50 to 80 degrees Fahrenheit (10 to 27 degrees Celsius).
Soil requirements:
Ericameria viscidiflora ssp. puberula grows in a variety of soil types, including clay, loam, and sandy soils. However, it prefers well-draining soils with a neutral pH between 6.5 and 7.5. It can tolerate soils that are slightly acidic or alkaline but struggles in highly acidic soils.
Cultivation
Ericameria viscidiflora ssp. puberula is adapted to arid and semiarid environments, so it thrives in well-drained soils and under full sun exposure. This plant can grow in various soil types, including sandy, loamy, and rocky soils. It prefers slightly acidic to neutral soils with a pH level ranging from 6.0 to 7.5. The plant is propagated by seeds or cuttings, and it can be grown in containers or directly in the ground.
Watering Needs
Ericameria viscidiflora ssp. puberula has moderate water requirements. The plant is drought-tolerant and can withstand long periods of dryness. However, it needs regular watering during the establishment phase. Mature plants should be watered sparingly, especially during periods of high humidity, as excessive moisture can lead to root rot. It is best to water the plant deeply and infrequently, allowing the soil to dry out between each irrigation cycle.
Fertilization
Ericameria viscidiflora ssp. puberula is a low-maintenance plant that does not require frequent fertilization. However, a light application of a balanced fertilizer can promote healthy growth and flowering. The plant can benefit from fertilization once a year, preferably in early spring, before the growing season begins. A slow-release fertilizer with equal amounts of nitrogen, phosphorus, and potassium can be incorporated into the soil around the base of the plant.
Pruning
Ericameria viscidiflora ssp. puberula does not require frequent pruning. However, it is recommended to trim back any dead or diseased branches as soon as they appear to maintain the plant's overall health and appearance. The best time to prune is in late winter or early spring before the growing season begins. Pruning can also be done after the plant has finished flowering to encourage bushier growth and more blooms in the following season.
Propagation of Ericameria viscidiflora (Hook.) L.C. Anders. ssp. puberula (D.C. Eat.) L.C. Anders.
Propagation of Ericameria viscidiflora (Hook.) L.C. Anders. ssp. puberula (D.C. Eat.) L.C. Anders. is mainly by seed. However, vegetative propagation by stem cuttings can also be successful. Sowing seeds directly in the soil during the fall or early winter is the best method, as the seeds need exposure to cold temperatures for germination.
Stratification can also be used to improve seed germination rates. This involves storing the seeds in a moist and cool (but not freezing) environment for around a month before sowing them. Scarification, which involves breaking down the seedcoat to allow moisture to penetrate and initiate germination, can also improve germination rates.
Stem cuttings, taken from semi-hardwood branches in the summer, can also be used for vegetative propagation. The cuttings should be around 4-6 inches long and taken from the current year's growth. Dip the cuttings in rooting hormone before planting them in a well-draining potting mix. Place the pot in a warm and bright area and keep the soil moist until the cuttings have rooted.
Disease Management
Ericameria viscidiflora (Hook.) L.C. Anders. ssp. puberula (D.C. Eat.) L.C. Anders. is generally a healthy plant, but there are a few diseases that can affect it. The most common diseases include:
- Leaf spot: The plant can develop leaf spots caused by fungal infections. These infections can lead to leaf drop and defoliation, which can weaken the plant. To manage leaf spot, remove infected leaves and dispose of them properly. Avoid overhead watering and use a fungicide if necessary.
- Root rot: Ericameria viscidiflora (Hook.) L.C. Anders. ssp. puberula (D.C. Eat.) L.C. Anders. can develop root rot caused by soil-borne pathogens. Poor drainage and overwatering can exacerbate root rot. To manage root rot, improve soil drainage and reduce watering frequency. Use a fungicide if necessary.
Pest Management
Ericameria viscidiflora (Hook.) L.C. Anders. ssp. puberula (D.C. Eat.) L.C. Anders. is also susceptible to some pests. The most common pests include:
- Mites: Mites can cause defoliation and stunted growth in the plant. To manage mites, use insecticidal soaps or oils and avoid over-fertilizing the plant.
- Scale: Scale insects can cause chlorosis and defoliation in the plant. To manage scale, prune heavily infested branches and use horticultural oil to suffocate the insects.
Overall, maintaining good plant health through proper watering, fertilizing, and pruning can prevent many disease and pest problems from occurring. Regularly inspecting the plant can help identify issues early and prevent their spread.
