Native to Europe and parts of temperate Asia, Convallaria majalis grows in woodland settings where soil stays cool, humus-rich, and evenly moist. Those conditions explain why the best soil for lily of the valley feels soft and moisture-retentive, yet still drains well after rain.
Its spreading rhizomes sit close to the surface and move through loose, loamy or silty ground more easily than through dense, compacted soil. Organic-rich structure supports steady moisture and airflow around the roots, which helps the plant remain healthy without sitting in stagnant, soggy conditions.
