Origin:
Lampranthus variabilis (Haw.) N.E.Br. is an evergreen succulent plant that belongs to the family Aizoaceae. The plant is native to South Africa, particularly in the Western and Eastern Cape provinces.
Common Names:
The plant is also known as:
- Trailing ice plant
- Variable ice plant
- Trailing vygie
- Variable vygie
Uses:
Lampranthus variabilis is commonly used as an ornamental plant due to its bright and showy flowers. The plant is also loved for its sprawling nature, which creates a beautiful groundcover for gardens and landscapes. It can also be grown in containers as a trailing plant for balconies and patios. In addition, the plant has medicinal properties and is used to treat ailments such as stomach issues and coughs.
General Appearance:
Lampranthus variabilis grows up to 20cm tall and spreads up to 45cm wide. The plant has fleshy, mid-green leaves that are cylindrical in shape and pointed at the tips. The leaves are arranged in opposite pairs along the fleshy stems. The flowers of the plant appear in clusters and are usually pink to reddish-purple in color. They bloom from late winter to early spring and attract bees and butterflies.
Light Requirements
Lampranthus variabilis requires full sun exposure for optimal growth. This plant species prefers to receive at least six hours of direct sunlight each day. It is important to note that this plant will not bloom without adequate sunlight exposure.
Temperature Requirements
Lampranthus variabilis thrives in warm temperatures, and is ideally suited to hot, dry climates. The plant can tolerate average temperatures of around 80°F (27°C), but it is known to grow optimally at temperatures above 90°F (32°C).
Soil Requirements
Lampranthus variabilis requires well-draining soil with a low to moderate nutrient content. This plant is not particularly fussy as to soil pH but prefers sandy or loamy soil to clay or heavy soil. It is recommended that you amend your soil with sand and organic matter to provide optimal growing conditions for this species.
Cultivation Methods
Lampranthus variabilis can be grown in well-draining, sandy soil that is enriched with organic matter. The plant prefers full sun and can be grown in both containers and in-ground settings. It is recommended to start the plant from seeds or cuttings in the spring or fall.
Watering Needs
Lampranthus variabilis is a drought-tolerant plant that can survive long periods without water. However, regular watering can help the plant to bloom and grow faster. Watering once a week during the growing season and reducing the frequency during the dormant winter months is recommended. The soil should be allowed to dry out between watering sessions.
Fertilization
A Balanced, slow-release fertilizer can be applied to the soil once or twice a year during the growing season. Avoid over-fertilizing, as it can lead to excessive foliage growth and fewer blooms. An organic fertilizer that is rich in phosphorus can be an excellent option to boost flowering.
Pruning
Lampranthus variabilis does not require extensive pruning to maintain its shape and size. However, regular deadheading of spent flowers can encourage new growth and prolong flowering. The plant can become leggy over time, and pruning the tips of branches can encourage bushy growth. It is recommended to prune in the late fall or early spring before the growing season begins.
Propagation of Lampranthus Variabilis
Lampranthus variabilis can be propagated through several methods including seed, stem cuttings, and division.
Seeds Propagation
Seeds of Lampranthus variabilis can be sown in a seedling mix in late winter or early spring, and they typically germinate within two to four weeks. The seeds should be sown on the surface of the soil mix and covered lightly with a fine layer of sand or vermiculite. The tray can be placed at a temperature of 70°F (21°C) for best results.
Stem Cuttings Propagation
Propagation of Lampranthus variabilis can also be done through stem cuttings. Cuttings of six inches in length can be taken from the parent plant in the spring or early summer and allowed to dry for a day or two before being planted in a well-draining soil mix. The cuttings should be planted at a depth of one inch, and the soil should be kept moist until they root, which may take up to four weeks.
Division
Dividing established plants is a quick way to propagate Lampranthus variabilis. Established plants can be divided in the spring when the new growth begins to emerge. Dig up the plant and gently separate the root-ball into several sections, each with a shoot or two. Replant the divisions immediately in well-draining soil and keep them moist until they establish new roots.
Disease Management
Lampranthus variabilis is relatively disease-resistant but can still be susceptible to certain diseases.
One common disease that can affect this plant is root rot. This is caused by overwatering or poor drainage. To prevent this, make sure the plant is growing in well-draining soil and avoid overwatering. If root rot is already present, improve drainage and reduce watering frequency.
Another disease that may affect Lampranthus variabilis is powdery mildew. This can be identified by a white powdery substance that appears on the leaves and stems. To manage powdery mildew, remove infected plant material and improve air circulation around the plant. Applying fungicides may also be necessary.
Pest Management
Just like with diseases, Lampranthus variabilis is generally resistant to pests, but some pests may still pose a threat to the plant.
One pest that may infest this plant is the spider mite. Spider mites are tiny insects that can cause discoloration and distortion on the leaves. To prevent spider mites, keep the plant well-hydrated and mist the leaves regularly to improve humidity. If spider mites are present, use insecticidal soaps or neem oil to control them.
Another pest that can affect Lampranthus variabilis is thrips. Thrips are tiny, slender insects that pierce the leaves and suck out the sap. This can cause bronzing or silvering of the foliage and can lead to stunted growth. To prevent thrips, remove all dead plant material and provide adequate ventilation. Applying insecticidal soaps or neem oil can also help control thrips.
Overall, the key to disease and pest management is prevention. By providing proper growing conditions and preventing stress on the plant, the likelihood of diseases and pests infesting Lampranthus variabilis is greatly reduced.
