Origin
Coreopsis goffardii Sherff, commonly referred to as Goffard tickseed, is a flowering plant that belongs to the family Asteraceae. The plant is native to North America and can be found growing naturally in the western parts of the United States, including Idaho, Montana, Utah, and Wyoming.
Common Names
Goffard tickseed is the most commonly used name for this plant. It is also known by other names such as Goffard coreopsis and Goffard's tickseed.
Uses
Coreopsis goffardii Sherff is a popular ornamental plant that is grown in gardens and landscapes due to its attractive flowers and foliage. The plant is grown for its long-lasting yellow flowers that bloom in the spring and summer seasons. The flowers attract a variety of pollinators, including bees, butterflies, and hummingbirds. The plant is also used for medicinal purposes by some Native American tribes. The roots of the plant are used to make a tea that is believed to have anti-inflammatory and pain-relieving properties.
General Appearance
Coreopsis goffardii Sherff is a herbaceous perennial plant that grows up to 1-2 feet tall. The plant has a clumping growth habit and has a bushy appearance. The leaves of the plant are lance-shaped, green, and about 1-2 inches long. The flowers of the plant are daisy-like with yellow petals and dark brown centers. The flowers are about 1-2 inches wide and bloom from May to July. The plant prefers full sun to partial shade and well-drained soils. It is drought-tolerant and easy to care for, making it a popular choice for gardeners and landscapers.
Growth Conditions for Coreopsis goffardii Sherff
Light: Coreopsis goffardii Sherff prefers full sun, meaning it requires at least six hours of direct sunlight per day to develop properly. Lack of sunlight results in poor flowering and less compact growth.
Temperature: The plant thrives in warm weather, with an optimal temperature range of 50 to 80°F (10 to 26°C). In cold weather, it becomes dormant or dies back to the ground. Freezing or below-freezing temperatures can severely damage or kill the plant.
Soil Type: The plant prefers well-drained soils with a pH range of 6.0 to 7.5. Excessively water-logged soils can cause root rot and stunt growth. An excellent sandy loam mix of equal parts of sand, loam, and compost will create ideal conditions for growing Coreopsis goffardii Sherff.
Water: The plant requires moderate watering, but it is also drought-tolerant once it is established. Overwatering can lead to waterlogged soil, which can cause root rot. It is best to water the plant when the soil is dry to the touch or when the leaves start to wilt.
Fertilizer: The plant requires minimal fertilization. Feeding the plant with a balanced, slow-release fertilizer once in the spring is sufficient. Applying too much fertilizer can cause excessive foliage growth and reduce flower production.
Propagation: The plant can be propagated through seed, division, or stem cutting. However, the easiest and most reliable method of propagation is through division during the spring season.
Cultivation methods for Coreopsis goffardii Sherff
Coreopsis goffardii Sherff, commonly known as Goff's Coreopsis, is a perennial plant that is native to south-central Arizona and northern Sonora, Mexico. It is a hardy plant that can be cultivated in USDA hardiness zones 9a to 11b. The plant prefers full sun to partial shade and well-drained soil. It can tolerate drought conditions, but it is not tolerant of wet soil. The plant can grow up to three feet tall and two feet wide.
Watering needs
The plant’s watering requirements will vary based on the climate, soil type, and other environmental factors. However, in general, the plant requires moderate watering. Water the plant when the top inch of the soil feels dry to the touch. Do not overwater the plant as it can lead to root rot and other diseases.
Fertilization
To encourage healthy growth and blooming, fertilize the plant with a balanced fertilizer that is rich in nitrogen, phosphorus, and potassium. Apply the fertilizer in the early spring, before new growth appears. Avoid fertilizing the plant during the summer months when growth slows down.
Pruning
Pruning is not necessary for the Coreopsis goffardii Sherff plant. However, deadheading the spent flowers can encourage the plant to produce more blooms. Cut the stalks of the flowers back to a side shoot or leaf node. This will also help to prevent the plant from self-seeding and becoming invasive.
Propagation of Coreopsis goffardii Sherff
Coreopsis goffardii Sherff, commonly known as Goffard's tickseed, is a beautiful flowering plant native to the United States. This plant is evergreen and produces pretty yellow flowers with brown centers that attract pollinators. Propagating Coreopsis goffardii Sherff is relatively easy, and there are several methods of propagation that can be used.
Propagating from Seeds
One of the most common ways of propagating Coreopsis goffardii Sherff is by seed. The best time to plant seeds is in early spring. The process involves collecting dry seeds from the flower heads and planting them in well-prepared soil. The seeds should be lightly covered with soil, and the soil should be kept consistently moist until the seeds germinate, which can take several weeks.
Propagating from Cuttings
Another way to propagate Coreopsis goffardii Sherff is through cuttings. This method is best done in late spring or early summer. To propagate through cuttings, cut a healthy stem about four to six inches long from the mother plant, ensuring that it has at least two leaves. Remove the lower leaves and cut the stem at an angle, dip the end in rooting hormone and place it in well-draining soil. Keep the soil moist and place the cutting in a shaded area until it roots, which can take around a month.
Propagating through Division
Propagating through division is an excellent way to rejuvenate older plants. This method is best done in spring or fall. To propagate through division, carefully remove the plant from the soil and gently separate the roots into smaller sections. Ensure that each section has enough roots and plant it in a new location with well-prepared soil and enough moisture.
Overall, Coreopsis goffardii Sherff is a beautiful and easy-to-grow plant that can be propagated through seeds, cuttings, and division. With proper care, these propagation methods will ensure the production of many beautiful Goffard's tickseed plants.
Disease and Pest Management for Coreopsis goffardii Sherff Plant
Coreopsis goffardii Sherff, commonly known as threadleaf coreopsis, is a perennial plant that produces stiff, thread-like leaves and bright yellow flowers. Although this plant is relatively low maintenance, it is not immune to certain diseases and pests that can affect its growth and overall health.
Common Diseases
One of the most common diseases that can affect Coreopsis goffardii Sherff is powdery mildew. This fungal disease appears as a white, powdery coating on leaves, stems, and flowers. To prevent powdery mildew, avoid overhead watering, provide adequate ventilation, and maintain good air circulation around the plant. In addition, you can apply a fungicide to the plant according to manufacturer's instructions.
Another disease that can infect Coreopsis goffardii Sherff is root rot. This disease is often caused by overwatering or poor soil drainage, which can lead to fungal growth and root damage. To prevent root rot, ensure that the soil is well-drained and avoid overwatering. If root rot does occur, remove the infected plant and dispose of it properly to avoid spreading the disease to other plants.
Common Pests
Coreopsis goffardii Sherff can also be susceptible to certain pests, including aphids and spider mites. Aphids are small, soft-bodied insects that feed on the sap of plants. They can be controlled by spraying the plant with a strong jet of water, applying insecticidal soap according to manufacturer's instructions, and attracting natural predators such as ladybugs and lacewings.
Spider mites are tiny pests that suck the sap of plants, causing a stippling or yellowing of the leaves. To control spider mites, you can use insecticidal soap or a miticide according to manufacturer's instructions. In addition, you can increase humidity around the plant by misting it with water, which will help keep spider mites at bay.
To maintain the health of Coreopsis goffardii Sherff, it is important to monitor the plant regularly for signs of disease and pest infestation and take action promptly to prevent further damage.
