Common Names
Aside from New England Blazing Star, the Liatris novae-angliae also goes by other names such as Meadow Blazing Star and Tall Gayfeather. The name Gayfeather comes from its unique appearance, with flowers that appear to be like feathery plumes extending from the stem.
Uses
The Liatris novae-angliae is commonly used for landscaping in gardens and parks due to its beautiful and unique appearance. It is also a popular choice for pollinator gardens, attracting a variety of bees and butterflies. In traditional medicine, the roots of Liatris novae-angliae have been used to treat several ailments such as coughs, colds, and kidney stones.
Light Requirements
Liatris novae-angliae (Lunell) Shinners requires full sunlight to grow and thrive. It is not recommended to keep it in shaded or partially shaded areas as it can lead to stunted growth and poor bloom development. Therefore, it is highly recommended to plant this species in areas where it can receive at least six to eight hours of direct sunlight each day.
Temperature Requirements
The typical temperature range for Liatris novae-angliae (Lunell) Shinners is between 60-80°F (15-27°C). This species can tolerate higher temperatures but tends to prefer cooler temperatures, especially during the summer season. Additionally, it is frost-tolerant and can survive in temperatures as low as -40°F (-40°C). However, It is advisable to keep the plant in an area with a consistent temperature range for optimal growth.
Soil Requirements
Liatris novae-angliae (Lunell) Shinners prefers well-draining and moderately fertile soil that is slightly acidic to neutral in pH between 5.5 - 7.0. A soil mixture containing sand, clay, and loam in equal parts is ideal for planting this species. This plant can tolerate occasional drought, but consistent moisture is necessary to stimulate growth and bloom development during the growing season; therefore, soil with good water-holding capacity is preferable.
Cultivation of Liatris novae-angliae
Liatris novae-angliae is relatively easy to grow and can thrive in most soil types, as long as they are well-draining. Plant it in an area with full sun exposure, as the plant requires at least six hours of direct sunlight daily to develop properly. The ideal time to plant the bulbs is in late spring when the soil has warmed up.
Watering Needs
Liatris novae-angliae can tolerate droughts, but it is essential to water it regularly during the growing season, especially in dry spells. When watering, ensure that the soil is moist but not waterlogged. Overwatering the plant can cause root rot or other fungal diseases.
Fertilization
Liatris novae-angliae does not require a lot of fertilizer, but a little boost during planting and once in the middle of the growing season can enhance the plant's growth. Apply a balanced slow-release fertilizer when planting, and a second application at half the recommended rate when the plant is halfway through its growing season.
Pruning
Pruning is unnecessary for Liatris novae-angliae plants, but if you wish to maintain a neat appearance or encourage more significant blooms, deadhead spent flowers and stem tips after flower production stops. Cut back the plants to a few inches off the ground in the late fall after the first frost. You can also divide the bulbs every three to four years in the early spring to promote healthy growth and propagation.
Propagation of Liatris novae-angliae (Lunell) Shinners
Liatris novae-angliae (Lunell) Shinners, also known as New England blazing star, is propagated through various methods, including seeds, division, and stem cuttings.
Propagation by Seeds
Propagation through seeds is the easiest way to reproduce Liatris novae-angliae. The seeds can either be purchased or collected from the plant itself. The ideal time to collect the seeds is in the fall when the blooms start to fade. Once collected, the seeds require stratification, which involves storing them in a damp, cool environment for several weeks before sowing.
After stratification, the seeds can be sown in trays filled with a mixture of compost and sand. Keep the soil consistently moist and place the tray in a partially shaded area. The seeds will germinate in two to three weeks, and once the seedlings have grown strong enough, they can be transplanted into individual containers or directly into the garden soil.
Propagation by Division
Liatris novae-angliae can be propagated through division during the early spring or fall. Divide the plant using a sharp knife or spade, ensuring that each section has a good root system. The divided plants can then be planted into individual containers or directly into the ground.
Propagation by Stem Cuttings
Propagation through stem cuttings is also possible but is more challenging than the other two methods. Select a healthy stem, free of diseases or damage, and cut it at a 45-degree angle. Remove the lower leaves from the stem, leaving only two to three at the tip. Dip the end of the stem in a rooting hormone and plant it in a pot filled with a mixture of compost and sand.
The cutting should be kept moist, and the pot should be covered with a plastic bag to create a humid environment. Place the pot in a partially shaded area and monitor the cutting's growth. Once the cutting has developed roots, it can be transplanted into the garden soil.
Disease and Pest Management for Liatris Novae-Angliae
Liatris Novae-Angliae, also known as New England Blazing Star, is a hardy and long-living perennial plant that is relatively pest resistant. However, like all plants, it is susceptible to certain diseases and pests that may affect its growth and development. Below are some common diseases and pests that may affect Liatris Novae-Angliae and how to manage them.
Common Diseases
1. Leaf spot: Leaf spot is a fungal disease that causes brown or black spots on the leaves of the plant. The spots may be circular or irregular in shape and may merge together, causing the leaf to wilt and die. To manage leaf spot, prune affected leaves immediately and dispose of them. Apply a fungicide to the plant to prevent the disease from spreading.
2. Rust: Rust is a fungal disease that causes orange or brown rust-colored spots on the leaves of the plant. The disease is most common in humid conditions and can spread quickly if not managed. To manage rust, prune and dispose of affected leaves immediately. Apply a fungicide to the plant and practice good garden hygiene to prevent the disease from spreading.
Common Pests
1. Aphids: Aphids are small, soft-bodied insects that feed on the sap of the plant. They are common pests of Liatris Novae-Angliae and can cause stunted growth and reduced flower production. To manage aphids, spray the plant with a strong stream of water to remove them. Apply an insecticidal soap or neem oil to the plant to prevent the pests from returning.
2. Spider Mites: Spider mites are tiny insects that suck the sap from the plant, causing leaves to turn yellow and fall off. A heavy infestation can cause the plant to die. To manage spider mites, remove and dispose of affected leaves immediately. Apply a miticide to the plant and increase the humidity levels around the plant to prevent the pests from spreading.
By practicing good garden hygiene and being vigilant for signs of disease and pest infestations, you can keep your Liatris Novae-Angliae healthy and thriving. If you are unsure about how to manage a particular disease or pest, consult with a local gardening expert or extension office for advice.
