Toad lilies are named for their spotted petals, squat shape, and shade-loving properties. In spite of their unusual name, they are beautiful flowers. These perennial plants grow best in partly shaded areas with moist and humus-enriched soil. Although it's important to keep your toad lilies watered, they are a delicate flower, so don't completely drench the soil. Toad lilies are small, but don't let their size fool you. They're tough and hardy plants that do well in varied climates. The flower resembles a small orchid and is speckled with various shades of purple.
