The plant produces yellow or orange-yellow flowers that are roughly 2-3 cm in diameter. The flowers grow in clusters at the top of the stems and are in bloom from July to September.Uses
Bidens scopulorum has been used for a variety of purposes by Native American tribes. The Navajo have traditionally used the plant as a medicinal herb for treating colds, stomachaches, and sore throats. The Cheyenne used the dried and powdered roots to treat toothaches. The plant is also used for landscape and erosion control purposes. Its spreading habit and tolerance to poor soils make it an attractive option for landscaping in dry and rocky regions.Conclusion
Bidens scopulorum, commonly known as Rocky Mountain beggarticks, is a plant species native to the western United States. It has lance-shaped leaves, yellow or orange-yellow flowers that grow in clusters, and is used for medicinal and landscaping purposes.Light Requirements
Bidens scopulorum typically thrives in areas with partial to full sun exposure. It needs around 6 hours of sunlight per day to grow properly. Inadequate amounts of sunlight can lead to stunted growth or even death of the plant. Therefore, it should be placed in a location where it can receive sufficient amounts of sunlight.
Temperature Requirements
This plant grows best in temperate to warm conditions. It can tolerate temperatures up to 30°C, but anything beyond that can interfere with its growth. Bidens scopulorum is generally frost-tolerant and can survive in temperatures as low as -10°C. However, it is recommended to avoid planting it in areas with extreme temperatures as it can lead to stunted growth or death of the plant.
Soil Requirements
Bidens scopulorum prefers well-drained moist soils that are rich in organic matter. The soil should be slightly acidic with a pH range of 4.5-7.0. This plant can tolerate a wide range of soil types, but it grows best in loam or sandy loam types. It is important to make sure the soil is well-aerated to prevent waterlogging.
Cultivation Methods:
Bidens scopulorum is an herbaceous perennial plant that belongs to the Aster family. The plant is native to North America and grows well in USDA zones 7 to 9. It prefers full sun to partial shade and well-drained soil rich in organic matter. The plant grows up to 2 feet tall and equally wide, making it an excellent choice for borders, beds, and containers. It is also suitable for rock gardens and naturalized areas.
Watering Needs:
Bidens scopulorum requires moderate watering, especially during the growing season. The plant prefers evenly moist soil that is neither too wet nor too dry. To achieve this, water the plant deeply once a week, or more often depending on the soil condition and weather conditions. Water the plant at the base, keeping the foliage dry to minimize the risk of diseases and pests.
Fertilization:
Bidens scopulorum benefits from regular fertilization during the growing season. Apply a slow-release balanced fertilizer such as 10-10-10, following the manufacturer's instructions. Alternatively, use a liquid fertilizer such as fish emulsion or seaweed extract every two weeks. Avoid over-fertilizing as it can lead to excessive growth and reduce the plant's flowering performance.
Pruning:
Bidens scopulorum does not require extensive pruning, but you can prune it to shape the plant and stimulate bushier growth. Prune the plant in early spring before new growth appears, cutting back the stems by one-third of their length. You can also deadhead the spent flowers throughout the growing season to encourage the plant to produce additional blooms. Remove any discolored, damaged, or diseased leaves and stems promptly to prevent the spread of pathogens and pests.
Propagation of Bidens Scopulorum (Sherff) T.G.J.Rayner
Bidens scopulorum (Sherff) T.G.J.Rayner is a plant species that belongs to the Asteraceae family. It is commonly known as Rio Grande Beggarticks, and it is native to the southwestern United States and northern Mexico. This plant is a perennial herb that grows up to 80 cm in height and produces yellow daisy-like flowers from August to October.
Propagation of Bidens scopulorum can be done through various methods, including seeds, stem cuttings, and division.
Propagation by Seeds
Bidens scopulorum seeds can be collected during the flowering season and sown in seed trays filled with a well-draining potting mix. The seeds should be covered lightly with soil and kept moist. They should germinate within two weeks and can be transplanted into larger containers or directly into the garden when they have grown big enough.
Propagation by Stem Cuttings
Stem cuttings of Bidens scopulorum can be taken in the summer from new growth. The cuttings should be around 10 cm long and should be taken from the upper part of the stem. Remove the lower leaves from the cutting and dip the cut end into a rooting hormone. Insert the cutting into a pot filled with a well-draining potting mix and keep it moist. The cutting should start to root within a few weeks and can be transplanted into a larger pot or directly into the garden.
Propagation by Division
Bidens scopulorum can also be propagated through division. This method involves dividing the plant into smaller sections and replanting them. This is best done in the spring when the plant is actively growing. Carefully dig up the plant and separate the roots into smaller sections, making sure each section has some stems and foliage. Replant the divisions into new containers or directly into the garden, keeping the soil moist.
Overall, Bidens scopulorum (Sherff) T.G.J.Rayner can be propagated through various methods, including seeds, stem cuttings, and division. Each method has its advantages and disadvantages, but they all provide an effective way to propagate this beautiful plant species.
Disease Management:
Bidens scopulorum is relatively resistant to diseases, but as with any plant, there is always a risk of infection. One common disease that can affect this plant is powdery mildew, which presents as a white, powdery substance on the leaves. To manage powdery mildew, remove any infected leaves and apply a fungicide to prevent its spread.
Another disease that can impact Bidens scopulorum is root rot, which causes the plant's roots to decay and can ultimately lead to its death. To manage root rot, ensure the plant is not overwatered, as excess water can lead to the disease. If root rot is present, remove the affected portion of the plant and treat with a fungicide.
Pest Management:
There are several pests that may target Bidens scopulorum, including spider mites, aphids, and whiteflies. These pests can cause damage to the plant by feeding on its leaves and sucking out the sap.
To manage spider mites, rinse the plant with a strong jet of water to knock them off the leaves. Repeat this process every few days, as mites are known for their ability to reproduce quickly. For severe infestations, an insecticidal soap or neem oil can be applied.
Aphids and whiteflies can be managed with a similar approach, by rinsing the plant with water and treating with insecticidal soap or neem oil as needed. It's important to note that while pesticides can be effective against pests, they should be used sparingly and with caution, as they may also harm beneficial insects and pollinators.
