Lithops, also known as “pebble plants” or “living stones,” are a type of small, succulent plant native to the arid regions of southern Africa. These fascinating plants are known for their unique, stone-like appearance and ability to blend in with their surroundings, which helps them survive in their harsh, desert environment. They (also known as “living stones”) are a type of mesemb, or a member of the family Aizoaceae. In this guide, we will discuss the unique features of lithops plants and provide tips for caring for and propagating these interesting succulent plants.
What is a Mesemb?
Mesembs, also known as “mesembs” or “mesembryanthemums,” are a group of flowering plants that are native to the arid regions of southern Africa. They are members of the family Aizoaceae, which includes more than 2,000 species of succulent plants.
Mesembs are known for their colorful, daisy-like flowers and thick, succulent leaves, which are often arranged in a rosette pattern. They are adapted to survive in arid environments, and are able to store water in their leaves and stems, allowing them to tolerate prolonged periods of drought.

Mesembs are popular as ornamental plants, and are often grown as indoor or outdoor plants in warm, sunny locations. They are relatively low-maintenance and can be grown in a variety of soils, as long as they are well-draining. Mesembs are also popular with collectors, as many species are rare and have unique, attractive characteristics.
There are many different species of mesembs, including ice plants, vygies, lampranthus, delosperma, and aizoas. Some common species of mesembs include Aptenia cordifolia (heart-leaved ice plant), Carpobrotus edulis (Hottentot fig), and Delosperma cooperi (ice plant).

Unique Features
Lithops plants are small, slow-growing succulents that are native to the arid regions of southern Africa. They are known for their unique, stone-like appearance and ability to blend in with their surroundings, which helps them survive in their harsh, desert environment.
They have a compact, fleshy growth habit and typically produce just a single pair of leaves. These plants have thick, fleshy leaves that are fused together, forming a single, rounded body that resembles a stone or pebble. The leaves are often a mottled or striped pattern, with shades of green, brown, red, or yellow, which helps the plant blend in with its surroundings.

In addition to their unique appearance, they are also known for their ability to survive in extreme conditions. They are able to store water in their leaves and stems, which allows them to survive prolonged periods of drought. They are also able to tolerate extreme temperatures, making them a popular choice for indoor and outdoor gardens in a variety of climates.

Caring for Lithops Plants
Lithops plants are relatively low-maintenance and can thrive with minimal care. However, there are a few key factors to consider when caring for these unique succulent plants:
- Light: They prefer bright, indirect light, but they can tolerate partial shade. Avoid placing them in direct sun, as this can cause the leaves to become sunburnt.
- Water: They do not require frequent watering, and in fact, overwatering can be a common problem for these plants. It is generally recommended to water them once every two to four weeks, depending on the humidity and temperature of the environment.
- Soil: As with all succulent plants, it is important to use a well-draining soil mix for living stones plants. A mix of cactus soil and perlite or pumice works well, or you can make your own mix by combining equal parts potting soil, perlite, and sand. Avoid using soil mixes that retain moisture, as this can lead to overwatering.

- Fertilizer: They are generally not heavy feeders and do not require a lot of fertilization. A light application of a balanced, all-purpose fertilizer once a month during the growing season is sufficient. Avoid overfertilizing, as this can lead to leaf burn and other problems.
- Repotting: Living stones are slow-growing and do not require frequent repotting. Repot the plant only when it becomes overcrowded or the pot becomes too small for the plant. Choose a pot that is slightly larger than the current pot and use a well-draining soil mix.
Propagating Lithops Plants
Lithops plants are generally propagated from seeds or offsets. To propagate from seeds, follow these steps:
- Sow the seeds in a well-draining soil mix and cover with a thin layer of sand.
- Water the soil lightly, being careful not to wash away the seeds.
- Place the pot in a location with bright, indirect light and a temperature between 70-75°F.
- Keep the soil moist but not soggy, and water the plant every few days or as needed.
- Once the seeds have germinated and the seedlings have developed their first set of leaves, gradually reduce watering and allow the soil to dry out between waterings.
To propagate from offsets, follow these steps:
- Carefully remove the offsets from the parent plant, being sure to leave a small portion of the root attached.
- Plant the offsets in a well-draining soil mix and water lightly.
- Place the pot in a location with bright, indirect light and a temperature between 70-75°F.
- Keep the soil moist but not soggy, and water the offsets every few days or as needed.
- Once the offsets have rooted and established themselves, gradually reduce watering and allow the soil to dry out between waterings.
How do you tell when lithops going into dormancy?
Lithops, also known as “living stones,” naturally go through a dormant period during the summer months. During this time, the plant will reduce its water consumption and slow down its growth. Here are some signs that your lithops is going into dormancy:
- The leaves become less plump: As the plant reduces its water intake, the leaves will become less plump and more shriveled in appearance.
- The plant stops growing: Lithops typically grow during the cooler months and slow down or stop growing during the summer.
- The old leaves start to dry up: During dormancy, the plant will start to reabsorb the nutrients from its older leaves, causing them to dry up and wither away.
- The plant may change color: Some lithops varieties may change color during dormancy, with some becoming more red or brown in color.
It’s important to avoid watering your lithops during its dormant period, as this can cause the plant to rot. Instead, wait until the new growth starts to appear in the fall before resuming regular watering.
Conclusion
Lithops plants are unique, stone-like succulent plants that are native to the arid regions of southern Africa. They are known for their ability to blend in with their surroundings and tolerate extreme conditions, making them a popular choice for indoor and outdoor gardens. When caring for them, it is important to provide bright, indirect light, use a well-draining soil mix, water infrequently, and avoid overfertilizing. Living stones can be propagated from seeds or offsets, and with proper care, they can thrive and make an interesting and attractive addition to your garden.
