Origin
Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz, commonly known as the Silver Lotus or Silvery Deervetch, is a species of legume native to California, Nevada, and Oregon in the United States.
Common Names
The Silver Lotus is also known as Silvery Deervetch, Silver Vetch, and Many-stemmed Deervetch.
Uses
The Silver Lotus plant is used in rangeland restoration, erosion control, and as a forage crop for livestock. It also provides important cover for wildlife in its native range.
The plant roots improve soil structure and help fix nitrogen, improving soil fertility. The plant's seeds and leaves were used by Native Americans and early settlers for food and medicinal purposes.
General Appearance
The Silver Lotus plant is a deciduous perennial that grows up to 3 feet tall. Its leaves are pinnately compound, consisting of numerous leaflets, and are silvery-green in color. The plant produces upright, elongated clusters of small, pink to purple pea-like flowers. The flowers are followed by seed pods that are covered in fine hairs.
The Silver Lotus plant has a deep, woody taproot and many stems arising from the base. It is drought-tolerant and prefers full sun to partial shade. The plant blooms from March to July and is a favorite of pollinators such as bees and butterflies.
Light requirements
Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz typically requires full sun exposure. It grows best in areas that receive at least six hours of direct sunlight per day. If the plant does not receive sufficient sunlight, it may not flower or produce as many seeds as it would under ideal conditions.
Temperature requirements
The plant can tolerate a wide range of temperatures. However, it thrives in areas with a Mediterranean climate, which is characterized by mild, wet winters and hot, dry summers. The ideal temperature range for this plant is between 65-75 degrees Fahrenheit (18-24 Celsius) during the day and 45-55 degrees Fahrenheit (7-13 Celsius) at night. Extreme temperature changes or frost can damage the plant and inhibit its growth.
Soil requirements
Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz thrives in well-drained soils. It can tolerate a wide range of soil pH from acidic to alkaline. However, the soil must be fertile and provide enough nutrients to support the plant's growth. The plant can grow in sandy loam, clay loam, or loam soils that are deep enough to hold moisture and allow for root growth.
Cultivation Methods
Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz is a perennial plant that grows well in a variety of soil types such as sandy, clay, acidic, and alkaline soils. It is easy to cultivate, and it requires full sun to grow. The plant thrives in areas with mild temperatures, and it is not frost resistant. It is best propagated from seeds or cuttings.
When planting from seeds, the seeds should be soaked in water for 12-24 hours to help break dormancy before planting. The seeds should be planted in well-draining soil and kept moist until they germinate. When planting from cuttings, the cuttings should be taken during the growing season and planted in a mixture of sand and perlite. The cuttings should be kept moist until they develop roots.
Watering Needs
The Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz requires regular watering during the growing season. The plant should be watered deeply, allowing the water to penetrate the soil to a depth of 6-8 inches. The plant should not be watered again until the top inch of soil is dry to the touch. Overwatering should be avoided as it can lead to root rot.
During the winter season, the plant should be given less water, but the soil should not be allowed to dry out completely. It is essential to check the soil moisture regularly to ensure that the plant is receiving the appropriate amount of water.
Fertilization
The Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz requires periodic fertilization to thrive. A slow-release fertilizer should be applied to the plant in the spring when new growth begins. The fertilizer should be applied again in mid-summer to support continued growth and development. Care must be taken not to overdose on fertilizer as it can cause damage to the plant.
Additionally, mulching with organic matter such as leaves or grass clippings can help provide nutrients to the plant as it decomposes.
Pruning
Pruning is an essential aspect of caring for the Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz. The plant should be pruned regularly to remove dead, diseased, or damaged branches. This helps to promote growth and development and prevent the spread of diseases. Pruning should be done during the dormant season to avoid damaging the new growth.
In addition to removing dead branches, pruning should also be done to control the size and shape of the plant. Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz can become leggy, and regular pruning can help to maintain a full and compact shape. Pruning should be done using sharp and clean pruning shears to avoid damaging the plant.
Propagation of Lotus argyraeus
Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz, commonly known as silver lotus or steamboat clover, is a member of the pea family. It is a low-growing perennial herbaceous plant that is native to California, USA. It has silver-green leaves and bright yellow flowers that bloom in spring and summer. The plant can be propagated through the following methods:
Seed Propagation
The easiest and most common method of propagating Lotus argyraeus is through seed. Collect the seeds from mature fruits, which are globular pods that turn brownish-black when mature. Soak the seeds overnight in water before planting in well-draining soil. You can either plant them directly into the ground or in a pot. Place the pot in a sunny spot and keep the soil moist. The seeds should germinate within 10 to 14 days.
Cutting Propagation
Another method of propagating Lotus argyraeus is through stem cuttings. Take a stem cutting in spring or early summer, before the plant starts to flower. Make sure the cutting is about 6 inches long and has at least two or three nodes. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in well-draining soil and water it. Cover the pot with a plastic bag and place it in a shaded area. After three to four weeks, check for roots. Once the roots are visible, remove the plastic bag and move the pot to a sunny spot.
Division Propagation
Lotus argyraeus can also be propagated through division. Divide the plant in early spring before it starts to grow. Dig up the plant and use a sharp knife or spade to cut the plant into sections. Make sure each section has at least one stem and some roots. Plant each section in well-draining soil and water it. Place the pot in a shaded area and keep the soil moist until new growth appears. Once the new growth has emerged, move the pot to a sunny spot.
Disease Management for Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz
Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz is not known to be susceptible to any particular diseases. However, environmental conditions such as excess humidity or prolonged wet periods can lead to the occurrence of fungal diseases including blights, rots, and powdery mildew.
The best course of action is to prevent these diseases by managing environmental factors. Here are some tips:
- Ensure proper drainage to avoid waterlogged soil.
- Avoid overhead watering.
- Allow for adequate air circulation between plants.

Pest Management for Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz
While not commonly affected by pests, Lotus argyraeus (Greene) Greene ssp. multicaulis (Ottley) Munz can attract some occasional pests such as aphids, spider mites, and thrips. These pests can cause stunted growth, discoloration, and deformation of leaves or flowers.
Here are some suggested ways to manage pests:
- Encourage the presence of natural predators such as ladybugs and lacewings by planting companion plants or providing suitable habitats.
- Handpick and discard any visible pests.
- Treat with insecticidal soap or horticultural oils if infestation is severe.
