Overview
Coreopsis schlechteri (Sherff) Burtt Davy is a flowering perennial plant from the Asteraceae family. It is native to Central America and can be found in Mexico and Guatemala. The plant is also known by the common names of Golden Dance and Tickseed.
Appearance
The Coreopsis schlechteri plant can grow up to 60 cm tall and has an upright, bushy growth habit. The leaves are narrow and lance-shaped, measuring up to 7.5 cm long, and are a green hue with a slightly furry texture on the surface. The flowers bloom in the summer, from July to October, producing butter-yellow petals with orange-brown centers. Each flower measures 2.5-4 cm in diameter and grows in clusters on sturdy stems.
Uses
Coreopsis schlechteri is highly valued as an ornamental plant for its vibrant yellow petals that can enhance any garden or landscape. The plant is also beneficial for attracting pollinators like bees and butterflies. Additionally, some cultures use the plant for various medicinal purposes. The flowers are traditionally used to treat fever, heart conditions, and digestive problems. The leaves and stems are used for treating skin conditions such as eczema and rashes. Overall, the plant provides numerous benefits in gardening and medicinal practices.
Light Requirements
The Coreopsis schlechteri requires full sun to partial shade for optimal growth. When planted in areas with high levels of sunlight, it produces more blooms that tend to last longer. Therefore, it is best to plant the plant in bright areas for maximum growth.
Temperature Requirements
The Coreopsis schlechteri can tolerate a range of temperatures, including slightly colder climates. It is ideal to plant this plant in areas where the temperature is between 68°F to 80°F (20°C to 27°C) for optimal growth. However, the plant requires protection from harsh weather conditions like winter frost as it is not very frost-resistant.
Soil Requirements
The Coreopsis schlechteri prefers well-draining soils that are well-aerated. It thrives in soils with a pH range of 5 to 6.5, which implies it does better in slightly acidic soils. However, the plant has high drought resistance; therefore, it can grow in dry soils without compromising its growth rate. It can also tolerate sandy soils but requires adequate watering to support its growth.
Cultivation Methods
Coreopsis schlechteri is a hardy plant that grows well in USDA zones 5-9. It prefers full sunlight and well-drained soil with moderate moisture. The plant can tolerate dry conditions and poor soil but does better in loam or sandy soil.
The best time to plant Coreopsis schlechteri is either in the fall or early spring. These seasons allow the plant to establish its roots well before blooming. Plant the seeds in shallow furrows, cover them with a thin layer of soil, and water lightly. The seeds should germinate within 2-3 weeks, and you can expect the flowers to bloom in early summer.
Watering Needs
Coreopsis schlechteri has moderate watering needs. The plant requires regular watering during the first growing season, but once established, it can tolerate dry soil. Water the plant at the base to avoid getting the foliage wet, which can cause diseases.
Make sure the soil is moist, but not waterlogged, and allow the top layer of soil to dry out before watering again. Depending on the climate, you may need to water the plant once or twice a week.
Fertilization
Coreopsis schlechteri is a low-maintenance plant and does not require frequent fertilization. However, you can apply a slow-release fertilizer during the growing season to promote healthy growth and vibrant blooms.
Apply the fertilizer according to the manufacturer's instructions and avoid over-fertilizing, as this can cause the plant to become leggy and prone to pests and diseases.
Pruning
Coreopsis schlechteri does not require regular pruning. However, you can deadhead the flowers to encourage more blooms and maintain a tidy appearance. Deadheading involves removing the spent flowers before they turn into seeds.
If the plant becomes too bushy or leggy, you can trim the top growth by one-third in late summer. However, avoid cutting the plant back to the ground, as this can harm the roots and delay blooming in the following season.
Propagation
Coreopsis schlechteri (Sherff) Burtt Davy can be propagated through various methods including seed and division.
Seed Propagation
Seeds can be collected from the plant after the flowers have bloomed and dried. The seeds should be planted in a well-draining soil mix, covered with a thin layer of soil, and watered regularly. It is also recommended to stratify the seeds, which involves storing them in a damp, cool environment for a period of time to mimic winter conditions. This encourages germination in the spring. After germination, the seedlings should be transplanted into individual containers until they are ready to be planted in a garden bed.
Division
The plant can also be propagated through division. This involves digging up the plant and separating the rhizomes or crown into smaller sections, each with a healthy root system. The sections can then be replanted in a well-draining soil mix and watered regularly. Division works best in early spring or fall when the plant is dormant.
Disease and Pest Management for Coreopsis schlechteri
Coreopsis schlechteri, also known as Schlechter’s tickseed, is a hardy perennial plant that is generally easy to grow and maintain. However, like all plants, it is susceptible to certain diseases and pests. Here are some common issues that may affect Coreopsis schlechteri and ways to manage them:
Common Diseases
Fungal leaf spot: This is a common disease that affects many plants, including Coreopsis schlechteri. It presents as circular, brown spots on the leaves. To manage fungal leaf spot, remove the infected leaves, and destroy them. Make sure to water the plant at the base and avoid getting water on the foliage. If the situation persists, use a fungicide that is labeled safe for use on Coreopsis schlechteri.
Root rot: Root rot is caused by overly wet soil and leads to discolored, mushy roots. To manage root rot, make sure the plant is not overwatered and allow the soil to dry between watering. If the soil is not well-draining, repot the plant in fresh soil.
Common Pests
Aphids: Aphids are small, pear-shaped insects that feed on the plant sap. They can be easily removed by washing the plant with a strong hose spray or by rubbing them off with a cotton swab dipped in alcohol. For severe infestations, use insecticidal soap or neem oil, following the instructions.
Spider Mites: Spider mites are tiny pests that cause yellowing leaves and fine webbing on the foliage. Natural predators like ladybugs and lacewings can control the population of spider mites. Alternatively, wash the plant with a strong hose spray or use acaricides, following the instructions.
By being vigilant with your Coreopsis schlechteri plant and monitoring for any symptoms of disease or pests, you can take action early, reducing potential damage and preserving the health and growth of your plant.
