Origin and Common Names
Chrysopsis resinolens A. Nels. is a perennial plant species that is native to North America, particularly in the western parts of the United States. It is part of the Asteraceae (Sunflower family) and commonly known as the sticky goldenweed.
General Appearance
The sticky goldenweed typically grows up to 1-3 feet tall and wide, with a woody base and many long stems covered with sticky glandular hairs, giving it its common name. The leaves of the plant are linear to oblong, up to 2 inches long, sticky, and gray-green in color. It produces several yellow, daisy-like flower heads on each stem, which generally appear in late summer or early fall.
Uses
The Chrysopsis resinolens A. Nels. has traditionally been used for medicinal purposes by several Native American tribes. The plant was used to treat digestive issues, coughs, colds, and rheumatism. The sticky stems were also used as a glue, and the flowers were used as a dye for textiles.
Today, the plant is mainly used for ornamental purposes. It is a popular choice for home gardens and landscaping due to its bright yellow flowers and unique gray-green foliage. Its high tolerance for drought and poor soil conditions also makes it an excellent choice for xeriscaping.
Light Requirements
The plant Chrysopsis resinolens A. Nels. thrives best in full sunlight conditions. This implies that the plant requires a minimum of six hours of sunlight every day. If you live in a location that does not offer such light conditions, it would be best to place the plant in an area with the most available sunlight, like near the window facing south. It would be best if you kept in mind that insufficient light could trigger the plant to become leggy or weak, resulting in weaker growth.
Soil Requirements
Well-drained soils are the best for growing Chrysopsis resinolens A. Nels. The plant prefers slightly acidic to neutral soil conditions, from pH 6.5 to 7.5. You should avoid cultivating the plant in heavy clay-based soils as they retain moisture for a more extended period. The soil type should be a mix of organic matter, sand, and clay in equal proportions.
Temperature Requirements
The optimum growth temperature for Chrysopsis resinolens A. Nels. is between 25 °C to 35 °C, and the plant can tolerate cold temperatures as low as 0 °C. The plant's growth rate slows down in temperatures below 20°C, and it may require additional warmth to blossom correctly.
Cultivation methods
The Chrysopsis resinolens A. Nels. plant is an easy-to-grow perennial that thrives in full sun and well-drained soil. The plant usually grows up to two feet tall and prefers a soil pH of 6.0 to 7.5. It can be propagated from seeds or cuttings.
Watering needs
This plant does not require much watering and can tolerate short periods of drought. However, it is best to keep the soil slightly moist to promote growth and maintain the plant's appearance. Water the plant deeply at least once a week during the growing season and reduce watering during the winter months.
Fertilization
Chrysopsis resinolens A. Nels. plants prefer nutrient-rich soil. Fertilize the plant with a balanced fertilizer at the beginning of the growing season, and once every four to six weeks thereafter. Avoid overfertilizing which can result in excess foliage and fewer flowers.
Pruning
Pruning helps to shape and rejuvenate Chrysopsis resinolens A. Nels. plants. Prune the plant in early spring by cutting back the stems to approximately six inches above the ground. This encourages new growth and promotes a bushier plant. Deadhead regularly to encourage blooming throughout the season.
Propagation of Chrysopsis resinolens A. Nels.
Chrysopsis resinolens A. Nels., commonly known as gumweed, is a perennial plant native to North America. It is a member of the Asteraceae family and is commonly found in dry, sunny areas. Propagation of Chrysopsis resinolens can be achieved through various methods.
Propagating from seeds
The easiest and most common method to propagate Chrysopsis resinolens is through seeds. Seeds can be sown directly in the ground during the fall season before the first frost. The soil should be prepared by loosening it to a depth of 4-6 inches before sowing the seeds. The seeds should be sown at a depth of 1/8 inch and covered lightly with soil. Germination should occur in 1-3 weeks, and the seedlings should be thinned to a spacing of 12-18 inches apart.
Propagating from cuttings
Propagation of Chrysopsis resinolens can also be achieved through cuttings. Cuttings should be taken in the early spring from mature plants. The cuttings should be 6-8 inches long and should be taken from the tips of the plant. Remove the lower leaves and plant the cutting in a container filled with well-draining soil mix. The container should be placed in a location where it will receive bright, indirect sunlight. Keep the soil moist, and roots should form in approximately 4-6 weeks.
Propagating from division
Division is another method that can be used to propagate Chrysopsis resinolens. It is best to divide the plant in the fall or early spring before the growing season begins. Dig up the entire plant and carefully separate the clumps with a sharp knife or gardening shears. Each clump should have a healthy root system, and the plant should be replanted immediately at the same depth as the original plant.
With the proper techniques, propagation of Chrysopsis resinolens can be easy and successful. Whether through seeds, cuttings, or division, you can increase your plant collection with this lovely perennial plant.
Disease and Pest Management for Chrysopsis resinolens A. Nels.
Chrysopsis resinolens A. Nels., commonly known as rosinweed, is a hardy plant that is well-loved for its bright yellow flowers and its ability to thrive in dry conditions. However, like any other plant, it is vulnerable to various diseases and pests that can negatively impact its growth and health. As such, it is important to be aware of the common diseases and pests that can affect Chrysopsis resinolens and to implement effective management strategies to keep them in check.
Common Diseases
Chrysopsis resinolens is susceptible to a number of fungal diseases, including leaf spot, stem rot, and powdery mildew. Leaf spot, caused by the fungi Cercospora and Phoma, is characterized by circular or irregular discolored spots on the leaves. Stem rot, caused by the fungi Sclerotinia, Botrytis, and Rhizoctonia, manifests as soft, wet rot on the stem tissue, which can be fatal to the plant if left untreated. Powdery mildew, caused by the fungi Erysiphe and Sphaerotheca, creates a white powdery film on the leaves and can stunt growth if left untreated.
Disease Management
To manage fungal diseases, it is important to practice good hygiene by removing infected plant debris and maintaining proper air circulation around the plant. Applying a fungicide can also help to prevent the spread of fungal spores. Copper fungicides are effective against leaf spot and powdery mildew, while fungicides containing thiophanate-methyl or azoxystrobin are effective against stem rot.
Common Pests
Chrysopsis resinolens is commonly attacked by spider mites, aphids, and leafhoppers. Spider mites are tiny insects that suck sap from the plant, causing leaves to turn yellow and drop prematurely. Aphids are small insects that also suck sap from the plant and can transmit viruses. Leafhoppers are small insects that feed on the plant and can transmit a variety of plant viruses.
Pest Management
To manage pests, it is important to monitor the plant regularly for signs of infestation. Pruning out heavily infested areas can help to prevent the spread of the infestation, while regular spraying with insecticidal soap or neem oil can help to control populations of spider mites and aphids. Leafhoppers can be controlled through the use of insecticides containing pyrethroids or neonicotinoids.
By staying vigilant and implementing effective disease and pest management strategies, Chrysopsis resinolens can thrive and continue to bring joy with its beautiful, vibrant blooms.
