Origin
Nummularia radicans, also known as creeping marsh pennywort, is native to the wetlands and marshes of North America, including Canada and the United States.
Common Names
Creeping marsh pennywort, dollarweed, dollarleaf, Navelwort, and Trailing marshpennywort.
Uses
Nummularia radicans is a valued ornamental plant used in landscaping for its attractive green foliage and small yellow flowers. It is found in gardens and landscaping projects because of its ability to adapt to a wide range of growing conditions, including partial shade, damp soil, and even standing water.
Nummularia radicans has also been used for medicinal purposes by Indigenous peoples. Native American tribes have used it as a remedy for sore throats, colds, and other respiratory ailments. It has also been used as a tea for fevers, upset stomachs, and liver dysfunctions in traditional medicine practice.
General Appearance
Nummularia radicans grows into a mat-like groundcover, reaching only a few inches in height. It is a herbaceous plant with glossy, round leaves that are bright green and scalloped in appearance. The flowers of the plant appear in the summer, and they are small, yellow, and grow in clusters at the base of the leaves.
The plant grows by extending runners above the ground that develop roots at various points along their lengths. This root system allows the plant to spread rapidly and create a dense mat of foliage where it is established.
Growth Conditions for Nummularia radicans
Nummularia radicans, commonly known as creeping pennywort, is a perennial herbaceous plant that is native to Europe and western Asia. It has a prostrate growth pattern and tends to form dense mats.
Light Requirements
Nummularia radicans prefers areas with partial shade or filtered sunlight. It can also tolerate full sun in cooler regions or if the soil is kept moist.
Temperature Requirements
This plant can tolerate a wide range of temperatures but prefers average to cool conditions. It is suitable for growing in USDA hardiness zones 7 through 11.
Soil Requirements
Nummularia radicans is adaptable to a variety of soil types, but prefers moist and well-drained soils that are rich in organic matter. It can also tolerate wet soils and occasional flooding.
Cultivation Methods:
Nummularia radicans, commonly known as creeping pennywort, is a low-growing perennial plant that is easy to cultivate. This plant can be propagated from cuttings or through division. To propagate through division, it's best to wait until the plant has grown to a clump size of about six inches in diameter. Then, gently dig out the roots, taking care not to damage them. Divide the plant into smaller pieces with roots attached and replant in a suitable location.
Watering Needs:
Nummularia radicans prefers evenly moist soil that is well-drained. Water the plant when the top inch of soil feels dry to the touch. Be careful not to overwater the plant as this can lead to root rot.
Fertilization:
Provide Nummularia radicans with a balanced fertilizer during the growing season. Apply the fertilizer once every 4-6 weeks to encourage healthy growth and flowering.
Pruning:
Nummularia radicans requires minimal pruning. However, it's best to trim any dead or damaged leaves or stems as soon as you notice them. This will encourage new growth and keep the plant looking tidy.
Propagation of Nummularia radicans
Nummularia radicans, commonly known as creeping buttonweed or dollarweed, is a low-growing perennial plant that is often grown as a ground cover. Propagation of this plant is relatively easy, and can be done by several different methods, including:
Division
The easiest and most common way to propagate Nummularia radicans is through division. This method is best done in the spring or fall when the plant is actively growing. To divide the plant, simply dig up the entire plant and carefully separate the root system into smaller sections, each with its own set of leaves and stems. Replant the sections immediately and water well.
Cuttings
Another way to propagate Nummularia radicans is by taking stem cuttings. Choose healthy stems that are at least 4 inches long, and cut them just below a node (the area on the stem where leaves emerge). Remove the leaves from the lower half of the stem, and dip the cut end in rooting hormone. Plant the cutting in a well-draining soil mixture, and keep it moist until it begins to root.
Seeds
Although less common, Nummularia radicans can be propagated from seed. The seeds are small and should be sown in a shallow container filled with seed-starting mix. Keep the soil moist, and place the container in a warm, bright location. The seeds should germinate in about 2 weeks. Once the seedlings have developed their first true leaves, they can be transplanted into individual pots or directly into the ground.
Disease and Pest Management for Nummularia radicans (Hook.) Kuntze
Nummularia radicans (Hook.) Kuntze, commonly known as creeping marshwort, is a small prostrate plant that belongs to the family Crassulaceae. Like other plants, it is susceptible to various pests and diseases that can cause damage to the plant. Here are some of the common pests and diseases that might affect Nummularia radicans, as well as ways to manage them.
Common Diseases
1. Fungal diseases: Fungal diseases like leaf spot and root rot can be a problem for Nummularia radicans. These diseases are caused by various fungi that thrive in moist conditions. To manage fungal diseases, avoid overwatering the plant and ensure good drainage. Remove any infected leaves and stems and dispose of them away from the plant.
2. Powdery mildew: Powdery mildew is a fungal disease that causes a powdery white coating on the leaves of the plant. To manage powdery mildew, avoid overhead watering and maintain good air circulation around the plant. Use fungicides if necessary, following the manufacturer's instructions.
Common Pests
1. Aphids: Aphids are small insects that feed on the sap of the plant, causing wilting and stunted growth. To manage aphids, spray the plant with a strong jet of water to dislodge the insects. Alternatively, use insecticidal soap or neem oil to control the infestation.
2. Spider mites: Spider mites are tiny pests that feed on the plant's juices, causing leaves to turn yellow and dry up. To manage spider mites, spray the plant with water to remove the pests. Use insecticidal soap or neem oil to control the infestation if necessary.
3. Mealybugs: Mealybugs are small, soft-bodied insects that secrete a powdery white substance on the plant's leaves and stems. To manage mealybugs, use a cotton swab dipped in alcohol or insecticidal soap to remove the insects. Repeat the treatment as necessary.
By monitoring your Nummularia radicans regularly and taking quick action against diseases and pests, you can keep your plant healthy and beautiful.
