Origin
Aster lowrieanus Porter var. incisus (Britt.) Porter, commonly known as Lowry's aster, is a perennial plant species that is a member of the Asteraceae family. This plant is native to North America, specifically found along the eastern seaboard of the United States.
Common Names
Besides Lowry's aster, this plant also goes by several other common names, such as cutleaf aster, cliff aster, and rock aster.
Uses
Aster lowrieanus Porter var. incisus is a popular plant in gardens and landscapes for its stunning appearance and versatility. It is also used to attract pollinators, such as bees and butterflies, to the garden. Some Native American tribes used the plant for medicinal purposes, including treating colds and coughs.
General Appearance
The plant has a compact and bushy growth habit, reaching a height of 1 to 3 feet. The leaves are long, narrow, and serrated, with a gray-green appearance. The flowers are daisy-like and have a bright violet-blue color, with a yellow center. They bloom from late summer to early fall, and its blooms make it a popular cut flower. The plant prefers full sun and well-drained soil and can be easily propagated using seeds or by taking stem cuttings.
Light Requirements
Aster lowrieanus Porter var. incisus (Britt.) Porter requires full sun to partial shade for ideal growth. This plant cannot tolerate heavy shade for an extended period. If grown indoors, it requires at least six to eight hours of direct sunlight through windows or artificial sources.
Temperature Requirements
This plant can withstand a wide range of temperatures but thrives in slightly cooler conditions. The ideal temperature for growth ranges between 60 to 75 degrees Fahrenheit. Temperatures above 80 degrees can cause the plant to become stressed, and it may not flower.
Soil Requirements
Aster lowrieanus Porter var. incisus (Britt.) Porter prefers a well-draining soil that is rich in organic matter. Soil pH ranges from 5.5 to 7.0. The soil must be moist and not waterlogged, as excessive water can lead to root rot and kill the plant. Adding compost or well-rotted manure to the soil before planting can improve soil fertility and water retention abilities.
Cultivation
Aster lowrieanus Porter var. incisus (Britt.) Porter is a long-lived perennial plant that requires well-drained soil. It should be planted in an area that receives full sunlight to partial shade. The plant is not tolerant of drought conditions, and therefore regular watering should be maintained. It should also be planted in an area where it can be protected from strong winds.
Watering Needs
It is essential to keep the soil moist but not overly saturated, as the plant is not tolerant to drought conditions. Regular watering should be maintained. However, it is important not to overwater the plant, as this can lead to root rot.
Fertilization
Regular fertilization is necessary for Aster lowrieanus Porter var. incisus (Britt.) Porter to maintain healthy growth and bloom. It is recommended to use a balanced fertilizer, such as 10-10-10. The fertilizer should be applied before the flowering season, and once again after the blooms have faded. Overuse of fertilizer can lead to poor growth and weak stems.
Pruning
Pruning Aster lowrieanus Porter var. incisus (Britt.) Porter after the blooming season is essential for maintaining healthy growth. The plant should be cut back to about half its height. Deadheading or removing the faded blooms during the growing season can extend the blooming period and encourage continued growth. If the plant becomes too leggy, it may be necessary to cut it back more severely to encourage new growth.
Propagation of Aster lowrieanus Porter var. incisus (Britt.) Porter
Aster lowrieanus Porter var. incisus (Britt.) Porter, commonly known as Lowrey's Aster, is a charming, herbaceous perennial plant that is native to the United States. It produces lovely, lavender-blue flowers that bloom from August through October, and can continue to bloom after the first frost in some areas. Lowrey's Aster is a great addition to any garden or landscape, and is relatively easy to propagate.
Propagation by Division
The best time to propagate Lowrey's Aster by division is in the spring, just as new growth begins to appear. To do this, dig up the plant and gently divide the root ball into several sections using a sharp, sterile knife or garden shears. Each section should have a healthy root system and several shoots or branches. Replant the divisions in well-draining soil, spacing them at least 12-18 inches apart.
Propagation by Stem Cuttings
Lowrey's Aster can also be propagated by stem cuttings, although this method can be a bit more challenging. To do this, take stem cuttings in the late spring or early summer, when the plant is actively growing. Cut a piece of stem that is about 4-6 inches long, making the cut just below a node or bud. Remove any leaves from the lower half of the stem, and dip the cut end in rooting hormone powder. Plant the cutting in a well-draining soil mixture, and keep it moist but not overly wet. It may take several weeks to several months for the cutting to take root and begin to grow.
Propagation by Seed
Finally, Lowrey's Aster can also be propagated by seed. This method is generally the easiest, but it can take longer for the plant to reach maturity. Sow the seeds in the spring, either indoors or directly in the garden. Cover the seeds lightly with soil, and keep them moist until they germinate. Transplant the seedlings once they are large enough to handle, and space them at least 12-18 inches apart.
Regardless of the propagation method you choose, be sure to provide adequate water and fertilizer to help the new plants establish themselves. With a little care, you can enjoy the lovely blooms of Lowrey's Aster for years to come.
Disease Management
Aster lowrieanus Porter var. incisus (Britt.) Porter plants may encounter several diseases that affect their leaves, stems, and roots. Below are some of the most common Aster lowrieanus diseases to watch out for, along with tips on how to manage them.
Powdery Mildew
Powdery mildew is a fungal disease that affects many plants, including Aster lowrieanus. It appears as a white, powdery coating on the leaves, stems, and flowers. To manage powdery mildew, remove and destroy any infected leaves and stems. Water your plants at the base to prevent water from getting on the foliage. Apply a fungicide spray recommended for powdery mildew.
Cercospora Leaf Spot
Cercospora leaf spot causes small, circular, brown spots on the leaves. These spots may have a yellow halo. To manage Cercospora leaf spot, remove and dispose of infected plant debris. Avoid using overhead irrigation and water plants at the base. Apply a fungicide spray recommended for Cercospora leaf spot.
Pest Management
Several pests may attack Aster lowrieanus plants, especially when grown in poor conditions. Below are some of the most common pests that may affect Aster lowrieanus plants and tips on how to manage them.
Aphids
Aphids are tiny, pear-shaped insects that may be green, black, or brown. They congregate on the undersides of leaves and stem tips, where they suck plant sap and exude honeydew, attracting ants. To manage aphids, spray the plants with a strong stream of water to wash off the insects. Apply insecticidal soap, horticultural oil, or neem oil spray recommended for aphids.
Spider Mites
Spider mites are tiny, eight-legged arachnids that may spin webbing on the leaves. They suck plant sap and cause yellowing, stippling, and browning of foliage. To manage spider mites, remove and discard heavily infested leaves and stems. Spray the plants with a strong stream of water to wash off the insects. Apply insecticidal soap or horticultural oil spray recommended for spider mites.
