Appearance
The plant can grow to be between 30 and 60 cm tall, and it has an upright and branching growth habit. The leaves are narrow, lance-shaped, and serrated with a length of 2.5 to 10 cm and a width of 2 to 10 mm. The flowers are small, yellow, and clustered at the top of the smooth stem. The blooms appear in late summer or early autumn and can last for several weeks.

Additionally, the plant is often used for ornamental purposes in gardens and is a favorite of pollinators like bees and butterflies.
Light Requirements
Solidago graminifolia var. major is a plant that thrives in full sunlight. It requires at least six hours of direct sunlight each day for optimal growth and blooming. If the plant is grown in partial shade, it may not produce as many blooms as it would in full sun.
Temperature Requirements
This particular variety of Solidago graminifolia is known to be quite hardy and can tolerate a wide range of temperatures. It can grow in USDA hardiness zones 3-8, which covers a wide range of areas across the United States.
However, the ideal temperature range for this plant is between 60-85 degrees Fahrenheit. If the temperature gets too hot, the plant may wilt and suffer damage. On the other hand, if it gets too cold, the plant may not grow as well and may have difficulty blooming.
Soil Requirements
Solidago graminifolia var. major prefers well-draining soil that is rich in organic matter. The soil should have a pH level between 5 and 7.5, which is slightly acidic to neutral. If the soil is too alkaline, the plant may have difficulty absorbing certain nutrients.
It is important to ensure that the soil does not become waterlogged or too soggy, as this can lead to root rot and other problems. Adding organic matter, such as compost or aged manure, can help improve soil quality and drainage.
Cultivation Methods for Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern.
Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern. can be propagated through seeds or cuttings. If starting from seeds, sow them in well-draining soil in the fall, and cover lightly with soil. Germination usually takes two to three weeks. For cuttings, take stem cuttings in the spring, dip the cut end in rooting hormone, and plant in well-prepared soil.
This plant prefers full sun to partial shade, and well-draining soil with a pH range of 5.5 to 6.5. It's recommended to space the plants 18 to 24 inches apart to allow for good air circulation and to prevent overcrowding.
Watering Needs for Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern.
When it comes to watering needs, Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern. prefers consistently moist soil, but not waterlogged. Water the plant deeply once a week in the absence of rain, and avoid overhead watering to prevent the spread of disease. In periods of drought, increase the frequency of watering to keep the soil moist.
Fertilization for Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern.
For optimal growth and health, it's recommended to fertilize the plant once a month during the growing season, from spring to fall. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium, and follow the package instructions for application amounts. Avoid applying fertilizer in the winter months.
Pruning Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern.
Pruning Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern. is not necessary, but can help promote a more bushy and compact habit. If pruning is desired, do so in the spring by cutting back the stems to about half their length. This will encourage the plant to produce more lateral branches and more flowers later in the season.
Propagation of Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern.
There are several methods of propagating Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern., including:
Seed Propagation
One of the most common methods of propagation for Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern. is through seeds. The seeds can be collected from the plant during the fall, or purchased from a reputable seed supplier. The seeds should be planted in the fall or winter, as they require a period of cold stratification in order to germinate.
Division
Another method of propagation for Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern. is through division. This method involves dividing an established plant into smaller sections, each of which can be planted to create a new plant. Division should be done in the spring or fall, when the plant is not actively growing.
Cuttings
Propagation of Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern. can also be done through cuttings. This method involves taking a cutting from an established plant, typically from a stem that is not flowering, and then planting the cutting in a well-draining soil mix. This method is best done in the spring or early summer, when the plant is actively growing.
No matter the propagation method chosen, it is important to ensure that the new plants are placed in an appropriate environment for their growth and that they are given sufficient water and nutrients to thrive.
Disease Management
Like other plants, Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern. is susceptible to certain diseases that may affect its growth and productivity. Some of the common diseases that can affect this plant include:
- Rust disease: This disease can cause yellow to brown lesions on the leaves of the plant, and eventually lead to leaf death. To manage rust disease, you can use a fungicide spray that contains copper or sulfur.
- Leaf spot: Leaf spot can cause small, circular spots on the leaves of the plant. Over time, the spots can combine and cause the leaves to turn yellow and die. To manage leaf spot, remove the infected leaves and apply a copper-based fungicide.
- Powdery mildew: Powdery mildew can cause a white, powdery substance to appear on the leaves, stems, and flowers of the plant. To manage powdery mildew, you can prune the plant to increase air circulation, and apply a fungicide spray that contains potassium bicarbonate.
Pest Management
Aside from diseases, Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern. can also be affected by pests. Some of the common pests that can infest this plant include:
- Aphids: Aphids are small, green insects that can suck the sap from the leaves and stems of the plant, causing them to wilt and die. To manage aphids, you can use a strong stream of water to wash them off the plant, or use insecticide soap.
- Mites: Mites are tiny, spider-like pests that can cause yellow, stippled leaves on the plant. To manage mites, you can apply insecticide soap or use a miticide spray.
- Caterpillars: Caterpillars can eat the leaves of the plant, causing holes and skeletonizing the leaves. To manage caterpillars, you can handpick them off the plant or use an insecticide spray.
It is important to monitor Solidago graminifolia (L.) Salisb. var. major (Michx.) Fern. regularly for any signs of diseases or pests, and take appropriate measures to manage them to ensure healthy and productive growth of the plant.
