Toad lilies (tricyrtis hirta) are perennial plants with low-growing foliage and speckled blooms that resemble toad skin. The flowers of the toad lily plant develop close to the stems and add a touch of color to shady parts of the garden during late summer and early fall. Toad lilies prefer partial to full shade and soil that is well-drained, but moist. They are available in various colors and are hardy in USDA zones 4 through 9.
Prepare the planting site by removing all weeds and large rocks. Loosen the soil to a depth of 6 inches. Add a 3- to 4-inch layer of organic compost and mix well with the loosened soil.
Dig a hole that is 6-inches deep and slightly larger than the toad lily bulb. Place the bulb on its side in the planting hole and cover with the loosened soil. Water until the soil is very moist, but not soggy.
Water whenever the soil is dry to the touch. Add a 2-inch layer of organic mulch once the new toad lily plants have emerged.
Examine the toad lilies regularly for signs of slug or snail infestation. If you notice a problem, promptly destroy any pests that you find on or around the plant and place slug baits around the lilies.
