The waffle plant (Hemigraphis spp.) is a warmth- and humidity-loving plant that's typically grown indoors as a houseplant. Waffle plants are easy to care for, as long as they receive enough moisture, and they can even grow in low-light conditions. Waffle plants are grown for their attractive, showy foliage. The leaves are commonly purplish-red on the undersides and grayish-green on the upper surfaces with upright or trailing stems. Waffle plants are best grown in hanging baskets so the stems can trail downward. In tropical climates, waffle plants can be grown as ground covers.
Place your waffle plant in full, direct sunlight, such as beside a bright, east-, west- or south-facing window. Maintain air temperatures around the plant of 60 to 85 degrees Fahrenheit.
Water your waffle plant thoroughly when the topmost layer of potting soil begins to dry out, providing water until it drains from the bottom of the pot. Keep the potting soil evenly moistened, and use warm water.
Feed your waffle plant once every two weeks while it's actively growing during spring and summer. Apply a water-soluble houseplant fertilizer and follow the dosage instructions on the label.
Mist your waffle plant daily or once every two to three days with warm, lime-free water. Also, to increase humidity, fill the drainage dish with pebbles and water, ensuring the pot is on top of the pebbles and not sitting in the water.
Repot your waffle plant once each year in spring, transferring it into a container that's the next size up. Pot the waffle plant into a container that has drainage holes in the bottom and is filled with a rich potting soil, such as a mix made for African violets or a mixture of equal parts leaf mold (humus) and peat moss.
