1. Lithops (Living Stones)

Plant description and origin

Lithops, also known as “Living Stones”, are a genus of succulents belonging to the Aizoaceae family. Originally from the arid regions of southern Africa, these plants have developed in rocky and desert areas, where they camouflage themselves between rocks to avoid predators. Their peculiar appearance and adaptability to extreme conditions make them one of the most fascinating and sought-after groups of succulents for collectors.

Unique characteristics

Lithops ‘ most distinctive feature is their striking resemblance to small stones or pebbles. This natural camouflage helps the plant protect itself from herbivores and survive in difficult habitats. Each plant consists of two thick, fleshy lobes, which store water to sustain the plant during periods of drought. In autumn, Lithops produce colorful, showy flowers that emerge from between the lobes, usually yellow or white, adding a vibrant touch to their usually discreet appearance.

Care Tips

Caring for Lithops can seem challenging, but with a few basic tips, you can ensure that these rare succulents thrive in your home:

• Light: Lithops need plenty of direct sunlight. Place them in a spot where they receive at least 4-5 hours of direct sunlight a day, such as a south or west-facing window.
• Watering: The main rule for watering Lithops is to avoid overwatering. During the summer, water moderately, only when the soil is completely dry. In winter, when the plant goes into dormancy, drastically reduce watering or stop watering altogether. Overwatering can lead to root rot.
• Soil: Use a well-drained substrate, such as a specific mix for cacti and succulents. Add coarse sand or perlite to improve drainage. Avoid soils that retain too much moisture.
• Pot: Choose shallow pots with drainage holes. Lithops have a shallow root system and do not require deep pots.
• Temperature: Although they tolerate high temperatures, lithops prefer moderate temperatures. Protect them from frost and extremely low temperatures.

With proper care, Lithops can become a long-lasting and fascinating addition to your plant collection. Their unique appearance and beautiful flowers are a rewarding treat for any succulent lover.

2. Euphorbia obesa (Baseball Plant)

Description and Origin

Euphorbia obesa, popularly known as “Baseball Plant”, is a succulent belonging to the Euphorbiaceae family. This plant originates from the arid regions of the Cape Province in South Africa. Due to its unique shape and robust appearance, it has become a favorite among collectors of rare succulents.

Distinctive features

Euphorbia obesa stands out for its spherical shape, reminiscent of a baseball, hence its popular name. When young, the plant is almost perfectly round, but as it gets older, it can become more cylindrical. Its surface is covered in vertical grooves that give the plant a segmented texture. In addition, Euphorbia obesa has fine marks or lines along its furrows, which can be green, grayish or reddish, depending on exposure to sunlight and the stage of growth.

How to Care for Rare Succulents

The Importance of Knowing the Specific Needs of Each Species

Caring for rare succulents can be a rewarding experience, but it requires careful attention to the specific needs of each species. Rare suc culents often have particular requirements in terms of light, water, soil and temperature, different from more common succulents. Understanding these needs is crucial to ensuring that your plants thrive and maintain their unique appearance. Before adding a rare succulent to your collection, research its native growing conditions and adapt your growing environment to mimic these conditions as best you can.

General Growing Recommendations

Although each species has its own particularities, some general growing practices can help keep rare succulents healthy:

• Watering: Most succulents prefer a watering regime that allows the soil to dry out completely between waterings. Overwatering is one of the most common causes of problems with succulents, leading to root rot. During the period of active growth (usually spring and summer), water moderately. In the dormant period (fall and winter), reduce the frequency of watering.
• Choice of pot: Use pots with good drainage systems. Clay or ceramic pots are recommended because they allow moisture to evaporate better. Avoid pots without drainage holes, as the accumulation of water can be fatal for succulents.
• Ideal substrate: Use a well-drained substrate specifically for cacti and succulents. Mixtures that include coarse sand, perlite or pumice will help improve drainage and prevent moisture build-up. An unsuitable substrate can retain too much water, damaging the roots.

How to identify and treat common problems

Even with the best care, rare succulents can face problems. Identifying and treating these problems quickly is essential to keeping your plants healthy.

• Overwatering: Signs of overwatering include soft, translucent and falling leaves. To treat, remove the plant from the soil, let the roots dry out completely and replant in a dry, well-drained substrate. Adjust your watering regime to avoid future problems.
• Pests: Common in succulents, pests such as mealybugs and spider mites can be identified by white spots, fine webs or damaged leaves. Treat pests by cleaning the plant with a mild soap and water solution or by using a suitable insecticide. For prevention, inspect your plants regularly and maintain good air circulation.
• Diseases: Fungi and root rot are common problems caused by excess humidity. Dark spots and soft areas on the stem or leaves can indicate a fungal infection. Treat by removing the affected parts and applying a fungicide. Make sure to adjust watering and improve drainage to prevent recurrences.

Keeping rare succulents healthy requires a balance between providing the necessary care and avoiding excess. By following these general recommendations and paying attention to the specific needs of each species, you can ensure that your rare succulents thrive and remain a vibrant and unique part of your collection.
