The plant known as mesen, Lampranthus spectabilis or "cat's claw", is one of the most appreciated succulents both for its resistance as well as for its ornamental capacity. Also known as Mesembryanthemum spectabilis, it belongs to the family Aizoaceae and is native to southern Africa. There are more than 250 varieties within its genus, and it stands out for its incredible flowering, drought tolerance, and adaptability to both heat and cold.
Botanical characteristics of the mesen
- Scientific name: Lampranthus spectabilis
- Synonyms: Mesembryanthemum spectabilis
- Common names: red mesem, cat's claw, sunbeam, lampranthus
- Family: Aizoaceae
- Origin: Arid and sunny areas of southern Africa
The mesen is a creeping succulent plant, with reddish stems that are little branched and rarely exceed 20-25 cm in height. triangular and fleshy leaves They have a bluish-green hue with small translucent dots reminiscent of dew. It is especially valued for its growth rate and the ability to cover areas, effectively covering both soils and slopes or massifs.
El The main attraction of the mesen plant is its flowers, which grow in clusters at the end of the stems and are characterized by their bright colors (purple, lilac, white, red, orange, and yellow). Medium-sized, they typically measure between 3 and 5 cm in diameter and have numerous fine petals, giving them a compact and attractive appearance.
Main species and varieties of Lampranthus
- Lampranthus spectabilis: The most common in gardens, it stands out for its intense lilac flowers and its carpeting appearance.
- Lampranthus aureus: Highly prized for the intense orange or yellow hue of its flowers. Its stems are more erect and can reach up to 50 cm.
- Lampranthus blandus: Pale pink flowers, especially used as ground cover both on slopes and in pots.
- Lampranthus zeyheri, multiradiatus, falcatus, amoenus: Some of the many species within the genus that share the hardiness and beauty of flowering.
Other related species, such as the so-called mesem ficoides or tricolor, produce flowers in up to three different colors on the same plant.
Flowering of the mesentery
The flowering of Lampranthus It is one of their most valued traits. It usually starts from late spring and extends, depending on the climate, well into summer. In temperate climates, some varieties can bloom as early as the second half of winter. The flowering period, generally spectacular and abundant, lasts for about 20 days, although each flower can remain open for approximately a week, unfolding only during hours of intense sunlight and closing on gray or shady days.
Flowers attract pollinators, which contributes to the garden's biodiversity. The colorfulness and abundance of flowers make the mesen perfect for bringing life and color to spaces like gardens, terraces, and balconies.
Uses in gardening and landscaping
The mesentery adapts to different styles and needs within the garden. It is ideal for:
- Rockeries and slopes: Due to its creeping growth and rapid coverage, it prevents erosion and provides color.
- Arid gardens and xeriscaping: Thanks to its tolerance to drought and sun, it is optimal for areas with low water maintenance.
- Pots and planters for terraces and balconies: Produces a very decorative hanging effect, especially in urban spaces.
- Solid and upholstered: They fill large areas with flowers, providing life during the flowering months.
- Coastal gardens: Its tolerance to salinity makes it suitable for seaside gardens.
Furthermore, the Mesen is resistant to pollution, so it withstands life well in urban environments.
Light and temperature conditions
The mesene requires full sun to develop healthily and ensure abundant flowering. A lack of direct light negatively affects flower color and quantity, as well as reducing their growth.
As for temperatures, it supports light and sporadic frosts, tolerating occasional temperatures as low as -7°C. However, it is recommended to protect it from persistent or excessive frost. Its African origin explains its excellent resistance to summer heat and coastal winds.
Soil type and substrate requirements
This plant thrives in almost any type of soil as long as it is well drainedIt adapts to both poor soils and sandy or calcareous substrates, but it is essential to avoid waterlogging, as excess moisture is its main enemy. To plant it in a pot, use a specific potting mix for cacti and succulents or a mixture of coarse sand and peat.
To ensure drainage, you can add a layer of gravel or clay to the bottom of the growing container. If your garden soil is clayey, it's a good idea to improve it with sand and organic matter to prevent water retention.
Planting and transplanting
The best time to plant or transplant the mesen is early spring. It can be transplanted into pots or into the final soil, always ensuring that the substrate is loose and drains well. In groundcover plantings, it is recommended to leave sufficient space (about 4-5 plants per square meter) for each plant to develop its full potential without excessive competition.
In the case of larger varieties such as Lampranthus aureus, a distance of 30 to 40 cm should be left between plants.
Irrigation and drought resistance
Mesem is very resistant to drought., something key to its success as an ornamental plant in warm or Mediterranean climates. Watering should be very moderate:
- In soil: Only water if the climate is very dry and there is no frequent rainfall. Once every 10-15 days in summer may be sufficient.
- In a pot or on a balcony: It will require weekly watering during warmer weather, ensuring the substrate dries completely between waterings. In the warmer months, the frequency can be increased to twice a week if the substrate is completely dry.
Es It is essential to avoid waterloggingExcess water is the main cause of fungal diseases and root rot. During the winter, reduce watering to a minimum.
Fertilization and fertilization
The mesen is not demanding in terms of nutrients, but appreciates a slight fertilized with organic compost or specific fertilizer for cacti and succulents, especially in late winter or early spring. If you prefer granulated fertilizers, choose slow-release formulas to reduce application frequency and avoid overfeeding.
During the flowering period, a monthly fertilization with diluted liquid fertilizer can prolong the abundance and duration of flowers. Avoid over-fertilizing, as this can promote leaf development and hinder flowering.
Pruning and maintenance
El Mesen maintenance is very simpleIt does not require structural pruning, but it is advisable to remove faded flowers and trim overgrown stems to control the shape and encourage plant renewal.
The ornamental life of the mesen is usually most attractive during the first 3-4 years. After this time, it is recommended to renew the plants using young cuttings obtained in early autumn. This ensures a dense and healthy cover.
Pests, diseases and common problems
The mesem is a plant very resistant to pests and diseases, but excessive humidity and waterlogging should be monitored, as they can cause the development of fungus and root rot. As for pests, it is rarely attacked by insects, but can occasionally be affected by mealybugs or aphids in poorly ventilated and humid environments.
To prevent problems, always use a well-drained substrate, reduce watering during cold weather, and promptly remove any diseased parts.
Multiplication and propagation of the mesentery
- By cuttings: The easiest and fastest way to multiply mesen. It's done in early fall or spring, using stems about 10-15 cm long with several leaves. Let the cut heal for a few hours and plant the cutting in moist, well-drained soil. Keep in a well-lit area, avoiding direct sunlight, until rooting takes place (2-3 weeks).
- By seeds: Although less common in home gardening, it can be sown in late winter or early spring, distributing the seeds over a sandy mixture and always keeping the substrate slightly moist until the sprouts emerge.
Renewing the mesin with cuttings every 3-4 years is recommended to maintain maximum density and leafiness.
Additional tips for growing and decorating
- Ideal for xeriscaping, sunny terraces and balconies.
- Perfect for coastal gardens thanks to its tolerance to salinity.
- Suitable for covering degraded or infertile areas due to its low nutritional requirements.
- Use varieties of different colors in combination to create attractive contrasts.
Thanks to its great rusticityEasy to propagate, and beautiful in bloom, the Mesen is one of the best options for those looking to bring color and life to their garden with minimal effort.
