Peperomia Caperata is a great choice for any collection! For lighting, they thrive best in bright, indirect light. Direct sunlight can be too harsh and may damage their leaves, but they also tolerate lower light conditions pretty well. Regarding watering, allow the top inch of the soil to dry out between waterings. They're quite sensitive to overwatering, which can lead to root rot, so make sure the pot has good drainage.
As for propagation, Peperomia Caperata can be propagated through leaf or stem cuttings. I've found that leaf cuttings in soil tend to be quite successful. Just take a healthy leaf with a bit of stem and plant it in a well-draining mix—keeping the soil slightly moist, but not soggy, encourages root growth. It can take a bit of patience, but the results are rewarding.
