Caladium

Caladiums are heat-loving tropical perennials that have almost unparalleled foliage and make showy houseplants. The plant's large, heart- or arrow-shaped, paper-thin leaves come in a striking array of colors and patterns. A mass of caladium is an explosion of whites, greens, reds, and pinks that are mottled, veined, and striped. They can easily offer the visual impact of having planted flowers while only being foliage plants. Though they are grown mainly for their foliage, they do produce some flowers, which start in the form of spathes, or spikes.
