Convallaria majuscula

Also known as:

American lily of the valley


Scientific Synonyms:

Convallaria montana


Convallaria majuscula is similar to, but should not be confused with the commonly found Eurasian species Convallaria majalis. Visually the only distinguishing characteristic, is that the flowering stems of C. majuscula are short, hence the flowers tend to buried within the leaves. The sweetly fragrant, bell-shaped flowers are usually ivory-white, sometimes tinged with pink. These give way to showy, reddish berry-like fruit.


American lily-of-the-valley is native to rich woodlands and margins, within a limited range of the central Appalachians. It enjoys moist, well-drained soils, and filtered light. It can be positioned in a location with more sun, but this will lead to premature deterioration of the foliage in summer. A cool spot in the garden is best. It is far less aggressive than its European counterpart, and can be grown in a perennial flower bed or rock garden, without risk of it becoming invasive. Flowering time is in May or June. Zones: 6-7


Propagate by clump division. Can be propagated from seed, but plants will be slow to mature.

Additional Notes

There are disagreements as to whether Convallaria majuscula is a separate species rather than an escaped variety. The remoteness of native populations, its rarity within its natural range, and its non-aggressive growing habit, all would seem to indicate that it is in fact a distinct species. Due to its scarcity, it should be considered endangered and not collected in the wild.
