Often referred to as radiator plants, these shrubs love the heat. This means choosing a location that boasts warm air or even humid conditions. Peperomia Argyreia plants thrive in temperatures spanning from 18°C (65°F) to 26°C (80°F).
The most celebrated indoor spot for Watermelon peperomias is in the west or east-facing room. This means the plant will be able to enjoy lots of light without becoming a victim of the intense midday sun.
If you only have a south-facing room to play with, ensure the plants are placed behind a sheer curtain or better still, away from the windowsill. These plants can also thrive in partial or complete shade as they're easily able to adapt to their surroundings.
