Hi,

The picture is very dark, but I think they are Waffle Plants which are named for their puckered leaves. Here’s a brighter picture of what Waffle House Plants in containers look like. Does this picture resemble your houseplants?

Here are a few care tips for Waffle HousePlants.

Provide Waffle Houseplants with bright indirect lightVery few houseplants should be placed in direct sun. High light refers only to bright indirect light since direct sun often burns the leaves of indoor houseplants. An area that is too hot and dry encourages Spider Mites and causes blooms to quickly fade. A northern exposure really doesn't provide enough light for high light plants. These plants need to be placed directly in front of an east-facing window, within 1-3 feet of a west-facing window, and within 5 ft. of a south facing window. A high light area has over 300 ft. candles of light. but no direct sun. Direct sun fades and burns the leaves of Waffle Plants.

Keep the soil of Waffle Plants evenly moist but never soggy. Do not allow the Waffle Plants to sit in water.

Provide as much humidity as possible for a Waffle Plant.

Fertilize your Waffle HousePlants once a month in the spring and summer when the plant is actively growing with a 5-10-5  fertilizerPlants need fertilizer only when they are actively growing. Slow growing plants in low light require very little plant food. Too much fertilizer is worse than not enough. Most plants prefer a water soluble plant food at 1/2 the recommended strength. Plants that are in bloom or dormant should not be fertilized. Houseplant food contains nitrogen (N), phosphorus (P), and potassium (K). A fertilizer containing these elements in equal proportion is considered a balanced plant food. Nitrogen helps in photosynthesis and encourages the growth of leaves and stems. Potassium and phosphorus also help in photosynthesis and aid in root and flower development. Most fertilizers have trace elements of other minerals that are lacking in the soil but are necessary for good plant growth. Fertilizers have a high salt content. If a plant is not producing new leaves and doesn’t absorb the fertilizer, salts build up in the soil. These salts can burn the roots, discolor the leaves, and cause new growth to be small.  .
