Origin
Lacinaria pilosa auct. non (Ait.) Heller, commonly known as the Hairy Blazing Star, is a wildflower that is native to the eastern and central regions of North America, including the United States and Canada.
Common Names
Aside from Hairy Blazing Star, Lacinaria pilosa is also known as Piliated Gayfeather, Shaggy Blazing Star, Hairy Liatris and Hairy Button Snakeroot
Appearance
The Hairy Blazing Star is a perennial plant that grows up to 4 feet in height. It bears long, hairy stems that are topped by spiky flowers in late summer to early autumn. The flowers are arranged in a dense column and are usually purple or pink. The leaves of Lacinaria pilosa are narrow, lance-shaped, and hairy with a rough texture.
Uses
The Hairy Blazing Star is commonly grown as an ornamental plant in gardens, parks, and natural landscapes because of its attractive appearance and long blooming period. It is also known for its medicinal properties and is used in traditional Native American medicine to treat various ailments such as fever, coughs, and skin conditions. The roots of Lacinaria pilosa contain compounds that have anti-inflammatory and diuretic properties. Some Native American tribes also use it as an herbal tea for its calming and relaxing effects.
Light Requirements
The Lacinaria pilosa plant requires full sun to partial shade to grow properly. It can tolerate some shade but tends to grow better and bloom more profusely in full sun. Therefore, it's best to plant it in a location that receives at least 6 hours of direct sunlight per day.
Temperature Requirements
The Lacinaria pilosa plant is tolerant of a range of temperatures but grows best in moderate temperatures. Ideally, the plant grows best in areas with temperatures ranging from 65°F to 75°F, and it can survive winter temperatures as low as 5°F.
Soil Requirements
The Lacinaria pilosa plant prefers well-draining, fertile soils that are rich in organic matter. The soil should have a pH range of 6.0 to 7.5. The plant does not grow well in waterlogged soils and requires regular watering to maintain soil moisture during dry periods. Adding compost or other organic matter to the soil can improve soil structure, fertility, and the plant's overall health.
In conclusion, providing the Lacinaria pilosa plant with full sun to partial shade, moderate temperatures, and well-draining, fertile soils can result in a thriving and healthy plant.
Cultivation Methods
Lacinaria pilosa is a perennial plant that prefers well-drained soils with a pH range of 6.5 to 7.5. It thrives in full sunlight or partial shade, and it is relatively low maintenance. The plant can be propagated via divisions or seeds which should be sown in spring in individual pots and transplanted later, once they are large enough.
Watering Needs
Lacinaria pilosa requires moderate watering. During hot and dry spells, the plant should be watered frequently. However, overwatering should be avoided, as it may lead to root rot. It is advisable to water the plant at the base, as watering the foliage may promote fungal growth.
Fertilization
Regular fertilization is essential for the healthy growth of Lacinaria pilosa. It is recommended to fertilize the plant once in early spring and once in late summer. A balanced fertilizer with an N-P-K ratio of 10-10-10 will provide the necessary nutrients. If the plant exhibits signs of chlorosis, it may be necessary to apply iron chelates.
Pruning
Deadheading spent flowers is necessary to promote continuous blooming throughout the growing season. The plant should be cut back to the ground in the fall after it has finished flowering. Additionally, pruning may be necessary to remove damaged or diseased branches.
Propagation of Lacinaria pilosa auct. non (Ait.) Heller
Lacinaria pilosa auct. non (Ait.) Heller, also known as rough blazing star, is a perennial wildflower native to the central and eastern regions of the United States. This plant can be propagated using multiple methods, including seed and vegetative propagation.
Seed Propagation
The most common way to propagate Lacinaria pilosa is through seeds. The seeds can be sown directly into well-draining soil in the fall or spring. After sowing, the soil should be kept moist until the seeds germinate, which should occur within 2-4 weeks. However, this method can be unpredictable since seeds may take up to two years to germinate.
Vegetative Propagation
Vegetative propagation of Lacinaria pilosa can be achieved through root division or stem cuttings. Root division should be done in the fall. The plants should be lifted carefully from the soil, and the roots should be separated to create new plants. Each section should have healthy roots and at least one growing point.
Stem cuttings can be taken from actively growing stems during the summer. The cuttings should be 5-8 cm in length and should be planted in well-draining potting soil. The pots should be kept in a warm and bright location until new growth appears, which takes up to 2-3 weeks. Once new growth appears, the cutting can be transplanted to their permanent location.
Overall, Lacinaria pilosa auct. non (Ait.) Heller can be propagated using seeds or by vegetative propagation. While seed propagation is the most common method, root division and stem cuttings can also be effective ways to increase the number of plants.
Disease Management
Lacinaria pilosa, commonly known as hairy blazing star, is generally resistant to most diseases. However, some diseases that may affect this plant include:
- Leaf spots: Caused by fungi, leaf spots appear as round or irregularly shaped discolored patches on the leaves. To control leaf spots, remove and destroy the affected leaves and avoid overhead watering, which promotes fungal growth.
- Root rot: Overwatering or poorly drained soil can lead to root rot, which causes the roots to turn brown and soft. To prevent root rot, ensure that the plant is planted in well-draining soil and avoid overwatering.
Pest Management
Lacinaria pilosa is also not usually troubled by pests. However, some of the pests that may attack the plant include:
- Aphids: Aphids are small, soft-bodied insects that suck the sap from the plant, causing the leaves to curl and lose vigor. To control aphids, use insecticidal soap or neem oil.
- Spider mites: Spider mites are tiny creatures that feed on the leaves, causing them to turn yellow and fall off. To prevent spider mites, ensure that the plant is regularly watered, and use insecticidal soap or neem oil to control the insects.
