Overview
Mesembryanthemum intrusum Kensit, also known as the Ice Plant, is a succulent plant with fleshy leaves that stores water to survive long periods of drought. The plant is native to South Africa but is widely cultivated in many parts of the world for its ornamental value. The Ice Plant derives its name from the glistening, sparkling appearance of its leaves that resemble ice crystals in the sun.
Description
Mesembryanthemum intrusum Kensit is a low-growing shrub with dense foliage that forms a spreading mat across the ground. The plant has a height of up to 15 cm and can spread up to 1 meter in diameter. The leaves are succulent, cylindrical, and shiny with a green-greyish color that appears almost transparent. The plant produces large, daisy-like flowers that range in color from white to pink to bright magenta with a diameter of about 5 cm during the summer months.
Common Names
The Ice Plant is known by several common names, including Heartleaf Ice Plant, Trailing Ice Plant, and Dumuriana Ice Plant. The plant is also referred to as Highway Ice Plant because it is often used as a groundcover along highways and roadsides in many parts of the world.
Uses
The Ice Plant is widely grown as an ornamental plant in gardens and landscapes across the world for its beautiful flowers and foliage. The plant's low-growing habit and succulent leaves make it an excellent choice for groundcovers, rock gardens, and container planting. The plant also has medicinal properties and is used in traditional medicine to treat a range of ailments, including stomachaches, fever, and coughs.
The Ice Plant is also used as a food source in many parts of South Africa, where it is known as Kruipvygie, meaning creeping mesemb. The plant's foliage is edible and is often used in salads, soups, and stews. However, it is essential to note that the plant's edible parts contain oxalic acid, which can be toxic to some animals and humans in high concentrations.
Light Requirements
Mesembryanthemum intrusum Kensit is a sun-loving plant that thrives under full sunlight. It requires a minimum of six hours of direct sunlight each day and can tolerate partial shade. When exposed to insufficient sunlight, the plant's growth will slow down, and it may produce smaller flowers.
Temperature Requirements
Mesembryanthemum intrusum Kensit prefers warm temperature, with an ideal range between 20°C to 27°C (68°F to 80°F). It can tolerate high temperatures of up to 38°C (100°F), but prolonged exposure to such temperature can negatively affect its growth. The plant can survive in slightly cooler temperatures as low as 5°C (41°F), but it may not store enough energy to initiate flowering.
Soil Requirements
Mesembryanthemum intrusum Kensit requires well-draining soil that can retain moisture. The plant is susceptible to root rot; hence it is essential to avoid water-logged soils. A soil mix consisting of garden loam, coarse sand, and organic matter such as compost is an ideal medium for this plant. Its pH should be between 6.0 and 7.0, slightly acidic to neutral.
Cultivation Methods
The Mesembryanthemum intrusum Kensit plant can be cultivated either in the garden or indoors. For outdoor planting, ensure that the soil is well-drained. The plant requires full sunlight for optimal growth. In indoor cultivation, choose a pot that is well-drained and fill it with a well-balanced mix of loam and sand.
Watering Needs
The Mesembryanthemum intrusum Kensit plant has moderate water needs. It is essential to avoid overwatering the plant as it can lead to rotting of the roots. Water the plant when the soil appears dry to the touch. When watering the plant, ensure that the water drains well and does not sit in the pot or container.
Fertilization
Fertilization is crucial for the growth and development of Mesembryanthemum intrusum Kensit plant. Use a balanced liquid fertilizer once every three weeks during the growing season. Avoid using too much fertilizer as it can lead to excessive foliage growth and weak stems.
Pruning
Pruning the Mesembryanthemum intrusum Kensit plant promotes bushier growth and prevents the plant from getting leggy. Prune the plant regularly, especially during the growing season. Pinch off the tips of the stems to encourage branching. Remove dead or damaged leaves and stems to encourage healthy growth.
Propagation of Mesembryanthemum intrusum Kensit
Mesembryanthemum intrusum Kensit, commonly known as the Invasive Mesembryanthemum, is a succulent plant that belongs to the family Aizoaceae. This plant is native to South Africa and is popularly grown as a ground cover or as an ornamental plant due to its unique characteristics.
Propagation through Seeds
The most common method of propagating Mesembryanthemum intrusum Kensit is through the use of seeds. It is important to note that fresh seeds have a higher chance of germinating compared to older seeds. The propagation process involves the following steps:
- Collect seeds from the mature plants during the flowering season (spring to early summer)
- Clean the seeds by removing any debris or dead materials
- Sow the seeds in well-draining soil mix in a shallow pot or tray
- Water the seeds lightly and cover the pot or tray with a plastic sheet to create a humid environment
- Place the pot or tray in a warm and bright location, avoiding direct sunlight
- Seedlings should appear within 2-3 weeks, and they can be transplanted into individual pots or outdoor beds after 6-8 weeks
Propagation through Stem Cuttings
Mesembryanthemum intrusum Kensit can also be propagated through stem cuttings. This method is best done during the active growing season, which is in spring or summer. The propagation process involves the following steps:
- Select a healthy, non-flowering stem from the mother plant and cut a 5-8 cm section
- Leave the cutting to dry for a day or two to reduce moisture content and prevent fungal growth
- Dip the cut end of the stem in a rooting hormone powder
- Plant the cutting in a well-draining soil mix and water the soil deeply
- Place the pot in a warm, well-lit location, avoiding direct sunlight
- Roots should appear within 2-3 weeks, and the cutting can be transferred into an individual pot or outdoor bed after 4-6 weeks
With proper care and maintenance, Mesembryanthemum intrusum Kensit can grow into a beautiful and thriving plant, providing a unique addition to any garden or landscape setting.

Root Rot
Root rot is caused by overwatering or poorly-draining soil. To prevent root rot, use a well-draining soil mix, and avoid overwatering. If your plant already shows signs of root rot, remove it from the soil, remove any affected roots, and replant in fresh soil.
Powdery Mildew
Powdery mildew is a fungal disease that affects the leaves of Mesembryanthemum Intrusum Kensit, causing a white, powdery coating. To prevent powdery mildew, avoid overwatering, keep the humidity low, and provide good air circulation. If your plant already shows signs of powdery mildew, remove any infected leaves and treat with a fungicide.
Leaf Spot
Leaf spot is a bacterial infection that affects the leaves of Mesembryanthemum Intrusum Kensit, causing brown spots. To prevent leaf spot, avoid splashing water on the leaves and provide good air circulation. If your plant already shows signs of leaf spot, remove any infected leaves and treat with a bactericide.
Common Pests
The most common pests that affect Mesembryanthemum Intrusum Kensit are spider mites, thrips, and aphids.
Spider Mites
Spider mites are tiny pests that feed on the leaves of Mesembryanthemum Intrusum Kensit, causing yellow spots and webbing. To prevent spider mites, keep the humidity low and provide good air circulation. If your plant already shows signs of spider mites, treat with an insecticidal soap or neem oil.
