Also known by its scientific name, hypoestes, the plants grow best in filtered sun, which helps maintain the bright leaf colors. The Splash varieties contain plants with white, pink and red leaf coloration. Give the polka-dot plants normal annual flower care to be successful. Moisten the soil when it begins to dry, and feed monthly with a general garden fertilizer. Plantings produce a small white flower, but it's not their attractive feature.
Day lilies are divided and replanted year-round.
Most growers like to divide them shortly after the plants bloom, but anytime during spring appears to be fine. Entire clumps of day lilies are usually lifted from the soil and the individual plants or small clusters of plants separated to start new collections. All but the lower 6 inches of foliage is removed at transplant time. The plants then are set in the ground and kept moist to begin growth.
