Lily of the valley (Convallaria majalis) produces fragrant bell-shaped, white flowers in late spring. This plant grows from rhizomes, which can be planted in late winter or early spring, whenever frost danger passes for your community. Gardeners should note that lily of the valley is toxic if ingested and the the plant can become invasive, taking over a patch of the garden. This plant works well as ground cover under a tree, or other tricky planting environments, advises Fine Gardening.
Choose a planting location for your lily of the valley in early spring, when frost danger passes for your area. The plants prefer part to full shade.
Dig holes for your lily of the valley rhizomes. Space the holes 1 to 2 inches apart and make the holes 3 inches deeper than the rhizomes, advises North Carolina State University. Remove rocks and weeds from the holes so the rhizomes can grow properly.
Place one rhizome in each hole so that the pointy end faces up.
Cover over each rhizome with soil, holding the rhizome vertically straight with one hand while you firm soil into the hole with the over.
Water your newly planted lily of the valley rhizomes.
