Lithops pseudotruncatella aka Pet Rock

Taxonomy

Lithops pseudotruncatella, a species of succulent in the family Aizoaceae, is often mistaken for Conophytum truncatum. However, with careful observation, it can be distinguished. Its name, meaning "fake-truncatum," reflects this confusion. This unique plant has received The Royal Horticultural Society's Award of Garden Merit and is native to various regions in Southern Africa. It forms clumps of pale buff leaves with olive-brown veining and mottling on the tips. In late summer and autumn, it produces stunning yellow flowers measuring 4cm across. These flowering living stones are a remarkable sight in the African deserts, thriving under the scorching sun. When touched, the Truncate Living Stone reveals its true identity as a plant. Its distinct features include two petals in shades of brown, gray, and pink, and the upper flat part of the leaf displays a branched linear or wreathed pattern. During its flowering period, it showcases a fragrance-free, yellow flower.

How to care for Pet Rock

Difficulty

Pet Rock presents a moderate level of care, which allows plant enthusiasts with some experience to expand their skills and knowledge.

Water

Pet Rock does best in dry soil and should only be watered sparingly.

Soil

To ensure the health of your Pet Rock, it's crucial to use a potting soil that won't hold too much moisture. A soil that drains well and contains perlite or vermiculite for drainage and organic matter for nutrition is ideal. Adding a few handfuls of perlite to store-bought cactus soil is an easy way to create this type of soil mix.

Lighting

Pet Rock thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Pet Rock.

Toxicity

The toxicity level of this plant has not been officially confirmed by Ploi. If there is a possibility of ingestion of plant material with an uncertain toxicity by you, a family member, or a pet, it is advisable to seek the assistance of a medical professional.

Humidity

Pet Rock prefers dry environments, so misting the plant to provide extra humidity and allow water to linger on the leaves can create an ideal environment for fungi that can be harmful.

Fertilizer

The growth rate of Pet Rock is slow and it doesn't necessitate additional fertilizing. By changing the soil in its pot annually, the plant should be provided with adequate nutrition. It is crucial to keep in mind that plants derive their energy from the sun, not fertilizers.
