This wonderfully weird watermelon-patterned plan can also be found under its botanical name of Peperomia argyreia.
Water: Wait until soil is dry to touch before watering. Bottom watering is recommended, but ensure plant doesn't sit in water too long as this may lead to rot.
Light: Like most peperomia, the watermelon loves bright, indirect light, although is can handle partial shade. Not enough light will lead to slow growth and loss of variegation.
Soil: Well draining soil is recommended.
Humidity: Mist occasionally.
Fertilizer: Fertilize with a water soluble houseplant fertilizer once a month during growing season. Do not fertilize during winter months,
