Mountain goldenrod has an average height of 2 to 5 feet and a spread one and a half times its height. It has lance-shaped leaves that are roughly 6 inches long with serrated edges. The leaves are green, hairless, and arranged alternately on the stem. The plant bears yellow flowers that grow in dense clusters toward the top of the stem. These flowers are 1/8 inch wide and attract butterflies and bees.
Uses
Oreostemma elatum has many medicinal properties and has been used for ages by Native Americans to treat various ailments such as sore throats, cold, coughs, and other respiratory problems. The plant is rich in anti-inflammatory, antioxidant, and antibacterial properties, which make it ideal for treating infections and inflammations. Additionally, the plant is an excellent food source for bees, butterflies, and other pollinators, making it an essential habitat plant for them.
Mountain goldenrod also has ornamental value and is widely grown in gardens and landscapes as an accent plant or for mass planting. It adds color and structure to the garden, making it more attractive.
In conclusion, Oreostemma elatum is a versatile and valuable plant that has many uses. Its medicinal properties, ornamental value, and role as a habitat plant make it an excellent choice for gardeners and nature lovers alike.Light Requirements
The Oreostemma elatum requires full sunlight or partial shade for optimal growth. It can tolerate shade, but the plant may not bloom as well. Therefore, it is best to grow the plant in a location where it will get plenty of sunlight.
Temperature Requirements
The Oreostemma elatum is a perennial plant that is native to mountainous regions, which means that it can tolerate cold temperatures. The plant can survive in USDA hardiness zones 5 through 8. However, it prefers cool nighttime temperatures. During the day, the plant can tolerate temperatures up to 85°F.
Soil Requirements
The Oreostemma elatum prefers well-drained soil that is rich in organic matter. The soil should have a pH level between 5.5 and 7.5. It is best to plant the Oreostemma elatum in soil that has been amended with compost or other organic materials. The plant can tolerate sandy or rocky soil, but it will not grow well in heavy clay soil.
Cultivation
Oreostemma elatum, commonly known as tall mountain aster, flourishes in full sun or partial shade with well-draining soil. The plant is native to rocky, mountainous regions and prefers soil with adequate drainage.
The plant is best grown through seeds in the late fall or early spring and typically takes between seven to 14 days to germinate in optimal soil and moisture conditions. Once sprouted, it is best to transplant young plants in groups of two or three to ensure ample growth, but also provide enough space for the roots to spread.
Watering Needs
Oreostemma elatum needs regular watering, especially during the first growth stages. The plant does not tolerate overwatering or waterlogged soil and could die if exposed to excess moisture. One should aim to provide the plant with adequate moisture based on the surrounding humidity and weather conditions.
It is always best to water the plants deeply a few times a week rather than watering lightly every day to ensure that the roots are getting enough moisture and going deeper into the soil.
Fertilization
Oreostemma elatum requires very little to no fertilizer when grown in optimal conditions. The native soils of the plant are typically low in nutrients, and the plant has adapted to these conditions. Applying a balanced organic fertilizer during initial planting could be useful for faster growth.
However, it is best to avoid fertilizing the plant too often, as it could promote excessive foliage growth, reduce bloom production and reduce the overall vigor of the plant.
Pruning
Oreostemma elatum does not require regular pruning. However, it is best to prune the plant annually, usually in late fall or early spring, to remove any dead, damaged, or diseased parts. This helps maintain the plant's health and growth and improves the chances of better blooms in the coming year.
One could also prune tall mountain aster to control the plant's height, reduce the need for staking, or to improve the overall shape of the plant. However, it is critical to be cautious when pruning, as excessive cutting could reduce the number of blooms in the coming year.
Propagation of Oreostemma elatum
Oreostemma elatum is a beautiful perennial plant that grows in the mountain meadows, rocky slopes, and dry hillsides of North America. The plant has a distinct appearance with its compact clusters of pink-purple flowers and hairy foliage.
The following are the two primary methods of propagating Oreostemma elatum:
Seeds
Oreostemma elatum can be grown from seeds. The propagation is best done in late spring or early fall when the temperature is cool. Collect mature seeds from the plant when the seed head is brown and dry. Spread the seeds in a tray with fine-textured soil, lightly cover them with soil, and keep it moist. The seedlings will germinate within three to four weeks.
The seedlings should be grown under light shade with good air circulation. Once they have grown to a reasonable size, you can transplant them into a permanent position in your garden. The young plants should be spaced about 30 cm apart.
Division
Dividing the plant from the root ball is an alternative means of propagation. It is a handy method to grow many new plants in a short time. The ideal time for dividing is early spring when growth is starting after winter dormancy.
Carefully dig up the plant and separate the root ball into smaller sections, each with some roots and leaves attached to it. Plant the divided sections in your garden, preferably in a nutrient-rich, well-draining soil that is exposed to full sun. Make sure the divided sections are spaced at least 30 cm apart. Water them well and keep the soil consistently moist until they're well established.
Propagation of Oreostemma elatum is relatively straightforward and simple. However, if you need further clarification about any aspect of growing this beautiful plant, contact your local horticulturist or plant specialist.
Disease Management
The Oreostemma elatum (Greene) Greene plant is susceptible to various fungal and bacterial diseases. Some of the most common diseases that affect the plant include:
- Leaf spot: Caused by the fungus Cercospora, this disease causes circular brown spots on leaves. To manage this disease, remove and destroy infected plant material and avoid overhead watering.
- Anthracnose: A fungal disease that causes dark spots on foliage. To manage this disease, prune infected parts of the plant, and avoid overhead irrigation. Applying fungicides can also help.
- Root rot: Caused by fungi or waterlogging, this disease causes the roots to rot. To manage this disease, improve soil drainage and avoid overwatering.
Pest Management
Several pests can attack the Oreostemma elatum (Greene) Greene plant, causing damage to the foliage and compromising plant health. Some of the common pests that affect the plant include:
- Aphids: Tiny insects that suck the sap from leaves, causing damage. To manage aphids, remove them manually with a strong stream of water, or apply insecticidal soap.
- Spider mites: These pests cause leaf yellowing and webbing. To manage spider mites, keep the environment humid, prune infected foliage, and apply insecticidal soap.
- Thrips: These pests feed on leaves, flowers, and fruits. To manage thrips, remove and destroy infected parts of the plant, and apply insecticidal soap.
Regular inspection, pruning, and general plant care can significantly reduce the incidence of pests and diseases on the Oreostemma elatum (Greene) Greene plant. Also, the use of organic control measures such as neem oil and insecticidal soaps is preferred over conventional pesticides.
