Mesembryanthemum semicylindricum Haw., also known as Half-cylinder-containing Mesembryanthemum, is a species of succulent plant in the Aizoaceae family. The plant is native to South Africa and can be found growing in sandy soil and rock crevices in the dry desert areas of the country.
General appearance
Mesembryanthemum semicylindricum Haw. is a low-growing succulent with a highly branched and spreading growth habit. The plant's leaves are cylindrical, fleshy, and green, with a slightly concave upper surface and a convex bottom surface. The leaves are arranged alternately along the stems and can grow up to 4 cm long.
The flowers of Mesembryanthemum semicylindricum Haw. grow in clusters at the tip of the stems. The flowers have a diameter of up to 3 cm and are made up of a large number of petals that vary in color from pink to purple. The flower buds are cylindrical and resemble the shape of the plant's leaves.
Common names
In addition to Half-cylinder-containing Mesembryanthemum, Mesembryanthemum semicylindricum Haw. is also known by the common names of Club-leaved Mesembryanthemum, Bontebokvygie, and Bakingstonevygie in South Africa.
Uses
In South Africa, Mesembryanthemum semicylindricum Haw. is used for medicinal purposes. The plant is believed to have anti-inflammatory properties and is used to treat stomach ailments, headaches, and insect bites. The plant is also used in traditional medicine to treat burns and skin conditions.
In cultivation, Mesembryanthemum semicylindricum Haw. is grown as an ornamental plant. The plant is drought-tolerant and can be grown in rock gardens, container gardens, or as a groundcover.
Light Requirements
Mesembryanthemum semicylindricum Haw. is an extremely sun-loving plant. It requires at least 6 hours of bright sunlight daily. It grows best in a location with full sun exposure. If grown indoors, it should be placed near a window that provides maximum natural light.
Temperature Requirements
The plant can tolerate a wide range of temperatures, with an optimum temperature between 18°C to 24°C. It is sensitive to frost and cannot survive extreme cold temperatures. The plant should be protected from frost, and the temperature should not drop below 0°C.
Soil Requirements
Mesembryanthemum semicylindricum Haw. is not very picky when it comes to soil type, but it requires well-draining soil. The soil should be nutrient-rich, with a pH level that ranges from 6.0 to 7.0. It grows well in sandy or loamy soil that is enriched with organic matter. It should be grown in a container with proper drainage to prevent waterlogging.
Cultivation
Mesembryanthemum semicylindricum Haw. is a relatively easy plant to cultivate in the home garden and requires minimal care. However, to ensure optimal growth, it's important to provide the right conditions.
The plant thrives in well-drained soil, so it's important to ensure that the soil is not too compact. Loamy soil mixed with perlite or sand will allow water to drain through the soil and prevent root rot.
It's also important to make sure the plants receive plenty of sunlight, as they grow best in full-sun conditions. Plant them in a location where they'll receive 6 to 8 hours of sunlight each day.
Watering Needs
Although relatively drought-tolerant, Mesembryanthemum semicylindricum Haw. requires regular watering during the growing season. Water the plant deeply once a week, allowing water to soak through the soil and reach the roots. Avoid overwatering, as this can lead to root rot.
During the winter months, reduce watering to once every two weeks, as the plant's growth slows down during this time.
Fertilization
Mesembryanthemum semicylindricum Haw. doesn't require a lot of fertilization, but some additional nutrients during the growing season can help improve growth and blooming. Use a water-soluble, balanced fertilizer every two to three weeks during the growing season.
During the winter months, reduce fertilization to once a month, as the plant's growth slows down during this time.
Pruning
Pruning is not necessary for Mesembryanthemum semicylindricum Haw. However, deadheading spent flowers and pinching back leggy stems can help promote bushier growth and encourage the plant to produce more blooms.
Pinch back the tips of stems that have become overly long, and remove any flowers that have wilted or died. This will help the plant conserve energy and produce more flowers.
Propagation of Mesembryanthemum semicylindricum Haw.
Mesembryanthemum semicylindricum Haw. is commonly known as the "intermediate ice plant" or "pigface." The plant is native to South Africa, where it thrives in dry, coastal regions. Propagation of Mesembryanthemum semicylindricum Haw. can be achieved in several ways, including seed propagation, stem, and leaf cuttings.
Seed Propagation
Mesembryanthemum semicylindricum Haw. is primarily propagated through seeds. The seeds of the plant are incredibly small, and it is essential to handle them with care during sowing. Sow the seeds in early spring, as soon as temperatures start to rise. The seeds should be planted in well-draining soil and kept moist but not waterlogged. It can take up to two weeks for the seeds to germinate. Once the seedlings are established, they can be transplanted outdoors.
Stem Cuttings
Mesembryanthemum semicylindricum Haw. can also be propagated through stem cuttings. Take 3-4 inch cuttings from the plant in the spring or summer. Remove the leaves from the bottom half of the stem and allow the cuttings to dry for several hours. Dip the cut end of the stem in rooting hormone and plant it in well-draining soil. Keep the soil moist and position the cutting in a spot with bright but indirect light. After a few weeks, the cutting should start to develop roots, and it can be planted outdoors.
Leaf Cuttings
Mesembryanthemum semicylindricum Haw. can also be propagated through leaf cuttings. Take a healthy leaf from the plant and make a clean cut across the leaf blade. Choose a spot on the leaf that has no visible damage or blemishes. Plant the leaf cutting in a well-draining soil mix and keep it moist. The leaf should develop roots and a small rosette of leaves over time.
In conclusion, Mesembryanthemum semicylindricum Haw. is a relatively easy plant to propagate. Whether you choose to start seeds, stem or leaf cuttings, the key is to keep the soil moist and ensure that the plant gets bright but indirect light.
Disease Management
Mesembryanthemum semicylindricum Haw. is generally a hardy plant and is not prone to many diseases. However, in certain conditions, the following diseases might attack the plant:
- Root rot: This occurs due to overwatering, and it affects the root system, causing the leaves to wilt and the plant to die. To manage this, it is best to ensure that the soil is well-draining and to avoid overwatering.
- Fungal infections: Mesembryanthemum semicylindricum Haw. is susceptible to fungal infections such as powdery mildew and botrytis. These infections may cause the leaves to wither, discolor, and die. The best way to manage this is by ensuring that the plant has good ventilation and by using a fungicide on the affected plants.
Pest Management
This succulent plant is also susceptible to infestations by pests such as:
- Mealybugs: These pests look like white cotton and tend to congregate in the leaf axils or on the stem. To control them, use a cotton swab dipped in rubbing alcohol to wipe them off.
- Aphids: These pests are small, soft-bodied insects that may colonize on the leaves and stems of the plant. To control aphids, use a stream of water to blast them from the plant or use insecticidal soap.
- Spider mites: These pests are tiny and barely visible, but their feeding damage causes yellowing and stippling of the leaves. To control spider mites, use a stream of water to blast them from the plant and use insecticidal soap.
Regularly inspecting the Mesembryanthemum semicylindricum Haw. and maintaining good plant hygiene can help prevent major pest and disease issues in this plant.
