Equisetum hyemale L. var. elatum (Engelm.) Morton is commonly known as scouring rush, rough horsetail, and giant horsetail. The plant gets its name from its rough texture, which was used by ancient people for scouring pots and pans.
Uses of Equisetum hyemale L. var. elatum (Engelm.) Morton
Equisetum hyemale L. var. elatum (Engelm.) Morton has a long history of use in traditional medicine. It was used by Native American tribes to treat kidney problems, wounds, and respiratory infections. Today, it is used in herbal medicine as a diuretic and for its anti-inflammatory properties.

General appearance of Equisetum hyemale L. var. elatum (Engelm.) Morton
Equisetum hyemale L. var. elatum (Engelm.) Morton is a perennial plant that grows up to 6 feet tall and has jointed stems that are hollow and cylindrical. It has no leaves but instead has whorls of thin, blackish-green branches that grow from the stem joints. The plant produces spores in cone-like structures at the tips of the stems. The stem is rough to the touch due to the presence of silicates in its tissue. The plant grows in clumps and spreads by underground rhizomes.
Light Requirements
Equisetum hyemale L. var. elatum prefers partial to full shade. It can tolerate some direct sunlight, but excessive exposure to the sun can cause leaf scorching and stunted growth. This plant can thrive in areas with low light conditions, making it an excellent choice for indoor gardening.
Temperature Requirements
The plant grows well in temperate regions with a temperature range between 20°C to 25°C. Equisetum hyemale L. var. elatum can tolerate some frost but doesn't fare well in extremely cold environments. It is recommended to keep the plant indoors during winter in areas experiencing frost or snow.
Soil Requirements
The plant can grow in a wide range of soils, but it prefers moist, well-draining soils. The soil should be rich in organic matter and slightly acidic, with a pH range of 5.0 to 6.5. Equisetum hyemale L. var. elatum has shallow root systems and can benefit from a layer of mulch to keep the soil moist. Additionally, the plant can grow well in aquatic environments and can be submerged in water as long as water quality remains high.
Cultivation methods
Equisetum hyemale L. var. elatum (Engelm.) Morton, commonly known as giant horsetail or scouring rush, is a perennial plant native to North America. It is a hardy and low maintenance plant that is commonly cultivated for its ornamental value. When planting, choose a location that receives partial to full shade and has moist, well-drained soil. Prepare the planting area by removing any rocks or debris and loosen the soil to ensure good root penetration. Plant the rhizomes at a depth no more than two inches below the soil surface, with a spacing of at least two to three feet between each plant.
Watering needs
Equisetum hyemale L. var. elatum (Engelm.) Morton requires consistent moisture to maintain its growth, making it a good choice for water gardens or boggy areas. The soil should be kept consistently moist but not oversaturated, as standing water may damage the rhizomes. During dry periods, water weekly to maintain the soil's moisture level. However, be careful not to overwater, as this may lead to root rot.
Fertilization
Equisetum hyemale L. var. elatum (Engelm.) Morton does not require heavy fertilization, but a small amount of nitrogen-rich fertilizer can promote healthy growth. Apply a balanced fertilizer, such as a 10-10-10 blend, during the spring or summer months. Avoid excessive fertilization, as it may produce rapid growth that can lead to weaker stems.
Pruning
Equisetum hyemale L. var. elatum (Engelm.) Morton is a relatively low maintenance plant that does not require much pruning. However, to maintain a tidy appearance, remove any yellowed or dead stems at the base of the plant. Additionally, cut back any diseased or damaged stems to prevent the spread of infection. During the winter months, the plant typically goes dormant, and the stems may appear brown or withered. Cut back these stems to the base of the plant in the spring just before new growth begins.
Propagation of Equisetum hyemale L. var. elatum (Engelm.) Morton
Equisetum hyemale L. var. elatum (Engelm.) Morton, commonly known as giant horsetail, is a hardy plant that can thrive in wet soil conditions. It is a popular ornamental plant that adds a touch of elegance to any landscape. Propagation of Equisetum hyemale L. var. elatum (Engelm.) Morton can be achieved through different methods, such as:
Division
One of the easiest ways to propagate Equisetum hyemale L. var. elatum (Engelm.) Morton is through division. The best time to divide the plant is in spring or fall. First, select a healthy mature plant with sufficient rhizomes. Next, lift the plant from the soil and gently separate the rhizomes using a sharp, sterilized tool. Ensure that each section has at least one growing point. Then, replant the sections in a prepared bed by digging a hole and covering the rhizomes with soil. Make sure that the plant is watered well and kept in a moist area until it gets established.
Cuttings
Another effective way of propagating Equisetum hyemale L. var. elatum (Engelm.) Morton is through cuttings. Take cuttings from a healthy parent plant in late spring or early summer when the plant is actively growing. Cut a section of the stem that is about 3-5 inches long with a sharp, sterilized tool. Ensure that the cutting has at least two nodes. Remove any leaves from the lower half of the cutting and place it in a container filled with moist soil. Keep the container in a shaded area and mist the cutting regularly to keep it moist. After a few weeks, the cutting will begin to grow roots, and it can be transplanted into the ground.
Spores
Equisetum hyemale L. var. elatum (Engelm.) Morton can also be propagated through spores. However, this method takes a long time and requires patience. Collect the spores from a mature plant in early spring when they are ripe and brown. Mix the spores with sand and sprinkle them on the surface of a moist seed-starting mix. Cover the container with a plastic bag to increase humidity and place it in a warm, bright location. Keep the soil moist by misting it regularly. After a few weeks to months, the spores will germinate, and small plants will start to grow. These can be transplanted into individual pots or a prepared bed when they are big enough to handle.
Disease Management
Equisetum hyemale L. var. elatum (Engelm.) Morton, commonly known as scouring rush, is known to be resistant to many diseases. However, it can still be affected by certain fungal and bacterial diseases, such as:
- Anthracnose: This fungal disease causes brown or black spots on the leaves and stems, which can eventually lead to defoliation. To manage anthracnose, remove infected plant debris, prune affected branches, and apply a fungicide according to the manufacturer's instructions.
- Rust: Rust is a fungal disease that can cause yellow or orange spots on the leaves, which eventually turn brown and fall off. To manage rust, remove infected plant debris, prune affected branches, and apply a fungicide according to the manufacturer's instructions.
- Botrytis blight: This fungal disease causes grayish-brown mold on the leaves, stems, and flowers, which can result in plant death. To manage botrytis blight, prune affected branches, improve air circulation around the plant, and apply a fungicide according to the manufacturer's instructions.
Pest Management
Scouring rush can also be affected by certain pests, such as:
- Spider mites: These tiny pests suck the sap from the plant, which can cause stunted growth, wilting, and yellowing of the leaves. To manage spider mites, spray the plant with a jet of water to dislodge them, or apply an insecticidal soap according to the manufacturer's instructions.
- Slugs and snails: These pests can cause holes in the leaves, and can even eat the entire plant. To manage slugs and snails, remove any hiding places near the plant, such as piles of leaves or weeds. You can also use traps or a barrier of copper tape around the plant.
- Caterpillars: Certain species of caterpillars can feed on the leaves of the plant, which can cause significant damage. To manage caterpillars, inspect the plant regularly and remove any caterpillars by hand. You can also use a biological control, such as Bacillus thuringiensis.
