As of my last knowledge update in January 2022, I don't have specific information about a succulent plant named "Pachyphytum rzedowskii (Pink Sedum)." This may be a specific cultivar or variety that has been introduced or popularized after that date.

Pachyphytum is a genus of succulent plants in the Crassulaceae family, and Sedum is another genus within the same family. They are known for their diverse and attractive foliage, often forming rosettes or unique leaf shapes.

If "Pachyphytum rzedowskii (Pink Sedum)" is indeed a specific variety, here are some general care tips that you can follow based on the typical care for Pachyphytum and Sedum succulents:

General Care Tips:

1. Light: Provide bright, indirect light. Many succulents, including Pachyphytum and Sedum varieties, prefer sunlight but may need protection from intense afternoon sun.

2. Watering: Allow the soil to dry out between waterings. Water thoroughly when you do water, but avoid overwatering, as succulents are susceptible to root rot.

3. Soil: Use a well-draining succulent or cactus mix. A mix with added perlite or sand can improve drainage.

4. Temperature: Most Pachyphytum and Sedum varieties prefer mild to warm temperatures. Protect them from frost, as many succulents are not frost-tolerant.

5. Container: Plant in containers with drainage holes to prevent waterlogging.

6. Fertilization: Fertilize sparingly during the growing season (spring and summer) with a diluted, balanced fertilizer. Avoid fertilizing during the dormant winter period.

7. Propagation: These succulents can be propagated from leaves or offsets. Allow cuttings to callus before planting them in soil.

Since specific care requirements can vary among different succulent varieties, it's recommended to observe your plant closely and adjust care based on its response. If you have specific information about the needs of "Pachyphytum rzedowskii (Pink Sedum)," consider following any additional care instructions provided by the seller or nursery where you obtained the plant.
