RECOMMENDED USDA GROWING ZONES: 3–7
1. Choose a cool, shaded location
Plant Lily of the Valley in partial to full shade with moist, well-drained soil. A location beneath deciduous trees or shrubs can work especially well, providing filtered light while protecting the plants from intense sun.
Lily of the Valley spreads underground by rhizomes and can gradually form a dense colony. Choose a location where this spreading habit is desirable and where the plants can remain relatively undisturbed.
2. Prepare your pips
Lily of the Valley is commonly sold as dormant pips attached to roots or rhizomes. Don't be concerned if they look small or dormant when they arrive.
If the roots appear dry, soak them in lukewarm water before planting to rehydrate them. Avoid leaving them submerged for an unnecessarily long period; they simply need enough time to rehydrate before going into the soil. Extension guidance specifically supports soaking dormant underground stems before planting.
3. Plant your pips
Arrange each pip with its roots spreading downward and outward. Plant shallowly so that the pointed top of the pip sits at or barely above the soil surface, then gently firm the soil around the roots.
For a permanent garden planting, space the pips approximately 4–6 inches apart. They will gradually spread and fill the spaces between plants. Water generously immediately after planting to settle the soil around the roots.
Under warm spring conditions, newly planted pips can begin producing top growth relatively quickly. Cooler soil temperatures may result in a slower start.
4. Keep the soil consistently moist
During active spring growth, provide enough water to keep the soil evenly moist but not waterlogged. Approximately 1 inch of total water per week from rainfall and irrigation is a useful general target when conditions are dry, although actual needs will vary with soil, temperature, and rainfall.
Continue providing supplemental water during dry periods in spring, summer, and fall, particularly while new plantings are becoming established. Established Lily of the Valley can tolerate some seasonal dryness, but performs especially well in moist, organically rich soil.
5. Let the foliage replenish the plants
After the fragrant, bell-shaped flowers finish blooming, leave the green foliage in place. The leaves continue photosynthesizing and replenishing the underground rhizomes for future growth.
Allow the foliage to yellow and decline naturally later in the season before removing it. Established Lily of the Valley spreads through its underground rhizomes and can eventually form a substantial groundcover, so monitor its spread if you are growing it beside less vigorous plants.
Safety Note:
All parts of Lily of the Valley are poisonous if ingested, including the flowers, leaves, roots, and berries. The plant contains cardiac glycosides that can cause potentially serious poisoning in people and animals. Keep plant material away from children and pets, and do not confuse Lily of the Valley with edible plants.
