This is the only fragrant native lily east of the Rocky Mountains. The Carolina lily occurs in well-drained soils, while the three closely related congeners with which it is sympatric, Lilium superbum, L. iridollae, and L. pyrophilum, occur in either wetlands or moist woods. Where it occurs with L. superbum, as it often does along roadsides, L. superbum grows in the adjacent depressions and L. michauxii on the bank. Among its close relatives, its small stature, broad petals, and consistently oblanceolate leaves with undulate margins and acuminate tips are diagnostic. In these features it rather resembles several of the western taxa, especially smaller plants of L. rubescens; vegetative or fruiting herbarium material of the two can be confused. In L. michauxii the leaves are noticeably fleshy and pale abaxially, relatively few in number, and, perhaps because whorls are also few (commonly 2–4), the leaves seem concentrated near the middle of the stem. This species is less common in the southwestern portion of its range, where it is sometimes encountered in vegetative form in shaded settings that preclude rapid growth and flowering. Like the other southeastern pendent-flowered lilies, the Carolina lily is pollinated by large swallowtail butterflies including the eastern tiger (Papilio glaucus Linnaeus, family Papilionidae).
