It seems there might be a bit of confusion. Sempervivum calcareum is a specific species of succulent commonly known as "Houseleek" or "Hen and Chicks," but it is not typically referred to as "Laxmi Kamal." The term "Laxmi Kamal" is more commonly associated with Haworthiopsis attenuata, also known as "Zebra Haworthia," which has a distinct zebra-like pattern on its leaves.

However, if you are specifically looking for information about Sempervivum calcareum, here are some general care guidelines:

Sempervivum calcareum (Houseleek) Care:

1. Light: Sempervivum prefers full sun to partial shade. It thrives in bright light conditions, but some protection from intense afternoon sun may be necessary, especially in hot climates.

2. Watering: Allow the soil to dry out between waterings. Sempervivum is drought-tolerant and prefers being on the drier side. Water thoroughly, and ensure good drainage to prevent waterlogging.

3. Soil: Plant in well-draining soil, preferably a succulent or cactus mix. Adding perlite or sand can improve drainage.

4. Temperature: Sempervivum is cold-hardy and can withstand freezing temperatures. However, it's essential to protect it from excessive heat in warmer climates.

5. Container: If growing in a container, ensure it has drainage holes to prevent water accumulation.

6. Fertilization: Sempervivum is not a heavy feeder. Fertilize sparingly with a balanced, diluted fertilizer during the growing season.

7. Propagation: Sempervivum propagates through offsets (chicks) that emerge around the base of the mature rosette. Allow offsets to develop before separating them and planting them in their location.

8. Pruning: Trim off any dead or dried-up leaves as needed to maintain the plant's appearance.

If you indeed meant a different succulent with the name "Laxmi Kamal," and it's not Sempervivum calcareum, please provide more details or a photo for accurate identification and care information.
