Overview
Lacinaria cylindracea (Michx.) Kuntze, also known as Cylindrical Blazing Star, is a species of flowering plant that belongs to the Asteraceae family. It is native to eastern North America, particularly in the United States and Canada.
Common Names
Cylindrical Blazing Star is also commonly known as Button Snakeroot or Button Blazing Star. It may also be referred to as Gayfeather, a common name shared by other plants in the genus Lacinaria.
Description
Lacinaria cylindracea has a long and narrow stem that can reach up to 6 feet tall. The stem is unbranched and rigid, with multiple narrow leaves that are grayish-green in color, ranging from 6 to 12 inches long. The plant blooms in mid-to-late summer, producing cylindrical heads that are pinkish-purple in color and approximately 6 inches long and 1 inch in diameter. The flower heads are made up of numerous tiny flowers that bloom from the top down, creating a fuzzy, bottlebrush-like appearance.
Uses
Historically, Indigenous peoples made medicinal use of the roots of Lacinaria cylindracea for various ailments, including fevers, venereal diseases, and pain relief. The plant is also a favorite of pollinators such as bees, butterflies, and hummingbirds, and is often grown as an ornamental plant in gardens and naturalized areas.
The plant is hardy and adaptable to a wide range of growing conditions, including full sun and well-drained soil. It is easy to grow from seed or clump division and requires minimal maintenance, making it an attractive choice for gardeners looking to incorporate native plants.
Light Requirements
Lacinaria cylindracea thrives in full sun and requires at least six hours of direct sunlight daily. The plant can tolerate partial shade, but excessive shade may cause stunted growth and reduced flower production.
Temperature Requirements
The ideal temperature range for Lacinaria cylindracea growth is between 60 and 85 degrees Fahrenheit. The plant is tolerant of heat and drought conditions but does not tolerate frost or freezing temperatures.
Soil Requirements
The plant prefers well-draining soils with a neutral pH between 6 and 7.5. It is adaptable to various soil types, including clay, loam, and sand. The soil must be moist but not waterlogged, as the plant may suffer root rot in overly saturated soils.
Cultivation methods
Lacinaria cylindracea, also known as button blazing star, is a herbaceous perennial plant that is native to North America. The plant prefers full sun to partial shade and moist, well-drained soil. It can grow up to 5 feet tall and 2 feet wide and has a clumping habit. Propagation can be done by seeds and division of the clumps.
Plant the button blazing star plant in the spring or fall, at a depth of about 1-2 inches and at a distance of 1-2 feet apart. Ensure the soil is well loosened and free of weeds before planting.
Watering needs
Lacinaria cylindracea requires regular watering, especially during the growing season. The plant prefers well-drained soil, and so over-watering should be avoided. Water the plants once a week, providing enough water to moisten the root zone without letting the soil become waterlogged.
During periods of drought, increase the frequency of watering, ensuring the soil is kept moist. Over-watering can lead to root rot, which can be harmful to the plant.
Fertilization
The button blazing star plant requires fertilization for healthy growth and development. Use a balanced fertilizer, applying it in the spring before the growing season begins. Follow the directions on the package for accurate application rates.
If the plant is not growing as expected, a second dose of fertilizer can be applied during mid-summer at half the rate of the spring application. Over-fertilization can cause excessive growth, which can weaken the plant.
Pruning
Lacinaria cylindracea does not require pruning, but occasional maintenance is beneficial. In the fall, after the plant has finished blooming, remove any dead or damaged leaves and stems. This will prevent pests and diseases from spreading.
During the growing season, remove any spent flowers to encourage continuous blooming. If the plant becomes too leggy, pinching back the growing tips will help promote bushier growth and increase flowering.
Propagation of Lacinaria cylindracea
Lacinaria cylindracea, commonly known as cylinder or button blazing star, is a perennial plant that belongs to the Asteraceae family. The plant is native to North America and is widely grown for its striking flowers that bloom in summer, attracting bees, butterflies, and other pollinators. Propagation is the process of producing new plants from existing ones, and various methods can be used to propagate Lacinaria cylindracea.
Seed Propagation
One of the most common methods of propagating Lacinaria cylindracea is through seeds. The seeds of the plant are small, and they should be sown in a well-draining seed mix in early spring. The seeds need a cold stratification period before planting, meaning they should be stored in the refrigerator for at least four weeks to simulate winter conditions. After this period, the seeds can be sown in a shallow furrow and covered lightly with soil. The soil should be kept moist, and the seeds will germinate in 10-14 days.
Division Propagation
Lacinaria cylindracea can also be propagated through division, which involves separating the plant's root ball into smaller sections and replanting them. This method is best carried out in early spring when the plant is beginning to grow again, making it easier to identify the sections to divide. The root ball should be carefully dug up and separated into sections using a sharp knife or spade. Each section should have its own set of healthy roots and leaves, and the sections can be replanted in well-draining soil with good organic matter.
Cuttings Propagation
Cuttings propagation involves taking a portion of a plant and using it to produce a new one. For Lacinaria cylindracea, the best time to take cuttings is in mid to late summer when the plant is mature and healthy. Select a healthy stem with several leaves and make a clean cut just below a node. Remove the lower leaves from the cutting and dip the cut end in rooting hormone before planting it in a well-draining soil mix. Cover the cutting with a plastic bag to retain moisture and place it in a bright but indirect light location. After several weeks, the cutting should start producing roots, and it can be transplanted into a larger pot or planted in the ground.
Disease and Pest Management for Lacinaria cylindracea
Lacinaria cylindracea, commonly known as the button snakeroot plant, is a native perennial that is highly valued in landscaping. This plant is known for its incredible ornamental value, abundant blooms, and low maintenance. However, it is vulnerable to various diseases and pests that can affect its growth and aesthetic value. We will highlight some of the common pests and diseases that affect the Lacinaria cylindracea and suggest ways to manage them.
Pests
Aphids: These small insects suck sap from the plant and cause deformation, yellowing of leaves, and wilting. The affected plant may also show stunted growth. To manage Aphids, you can apply insecticidal soap or neem oil.
Spider Mites: Spider mites are common during hot and dry weather. They feed on the underside of the leaves, causing yellowing or bronzing of the foliage. They can be managed by washing the plant with high-pressure water regularly or by applying insecticidal soap solution.
Leafhoppers: Leafhoppers are common pests with piercing mouthparts that cause yellow spotting, stunted growth, and deformed leaves. They can be managed through the use of pyrethrin-based insecticides or neem oil.
Diseases
Root Rot: Root rot is a fungal disease that affects the Lacinaria cylindracea. It thrives in wet and poorly drained soils. The affected plant may show wilted foliage even after watering. To manage root rot, ensure proper drainage and avoid overwatering.
Rust: Rust appears as yellow or orange spores on the underside of the leaves. It is a fungal disease that thrives in moist environmental conditions. A seriously rust-infested plant may lose its leaves and vigor. To manage rust, prune infected parts of the plant and apply fungicide.
Leaf Spots: This is a fungal disease caused by Alternaria or Cercospora species. It affects the leaves, causing spots or blotches that can grow larger, eventually causing defoliation. To manage leaf spots, ensure proper air circulation, and remove infected leaves.
Early identification and management of any pest or disease is essential to keep the plant healthy and attractive. Always ensure to follow the suggested management techniques and use responsibly any pesticide or fungicide.
