Why do Lily of the Valley and daffodils not grow together?

Lily of the Valley and daffodils do not typically grow together due to their differing environmental preferences and growth habits. Lily of the Valley thrives in shaded, moist areas, while daffodils prefer well-drained soil and full sun to partial shade. Additionally, the aggressive growth of Lily of the Valley can overshadow and compete with the daffodils for nutrients and light, making it challenging for them to coexist.
