Overview
Lily of the valley is cherished for its dainty, nodding white bells and one of the most beloved fragrances in the plant world, appearing for a few weeks in mid to late spring. Pairs of broad, glossy leaves rise from creeping underground stems to carpet shady ground.
Native to the cool woodlands of the Northern Hemisphere, Convallaria majalis spreads steadily by rhizomes (pips) and can form dense colonies, sometimes to the point of being invasive.
It carries deep cultural symbolism, featuring in May Day traditions and royal bouquets, but gardeners must respect that the entire plant is highly toxic if ingested.
How to identify it
- Flowers: Tiny, nodding, bell-shaped white (occasionally pink) flowers on one-sided arching stalks; powerfully sweet fragrance
- Leaves: Two or three broad, elliptical, glossy green basal leaves per shoot
- Habit: Low groundcover 6-12 in. tall, spreading by rhizomes into dense colonies
- Fruit: Small red-orange berries in late summer (highly poisonous)
- Bloom time: Mid to late spring
Care & growing
Light: Partial to full shade; ideal beneath trees and shrubs.
Water: Keep soil consistently moist, especially during active growth and bloom.
Soil: Rich, humusy, moisture-retentive soil; tolerates a range of conditions in shade.
Temperature: Hardy in USDA zones 3-8; needs winter cold for dormancy.
Feeding: A spring topdressing of compost or leaf mold is sufficient.
Propagation: Easiest by dividing the rhizomes (pips) in fall or early spring. Wear gloves and wash hands, as all parts are toxic; plant where its spreading habit can be contained.
Habitat & origin
Lily of the valley is native to cool, temperate woodlands across Europe, Asia, and parts of North America, where it carpets shaded forest floors in moist, humus-rich soil.
It is widely grown as an ornamental shade groundcover, though in favorable conditions it can spread aggressively and is considered invasive in some regions.
Uses & benefits
Ornamental: A classic fragrant groundcover for shade gardens, woodland plantings, and beneath shrubs; the cut sprays are prized for bouquets, including wedding and royal arrangements.
Cultural: A symbol of spring, humility, and renewal, central to French May Day (La Fête du Muguet) traditions.
Caution: Despite its use in perfumery for scent, the plant contains cardiac glycosides and is dangerously poisonous; it has no safe home medicinal or culinary use.
Frequently asked questions
Is lily of the valley poisonous?
Yes, extremely. All parts, including the attractive red berries, contain cardiac glycosides and are highly toxic to people and pets if eaten. Handle with care and keep away from children.
Does lily of the valley spread?
Yes, it spreads vigorously by underground rhizomes and can form dense colonies. In some areas it is considered invasive, so plant it where it can be contained.
Why won't my lily of the valley bloom?
Too much sun, dry soil, or overcrowded pips can reduce flowering. Give it moist, shady, humus-rich conditions and divide crowded colonies.
Can lily of the valley grow in sun?
It prefers partial to full shade. In hot, sunny spots the foliage scorches and the plant struggles; dappled woodland shade is ideal.
