Prefers a cool moist well-drained humus-rich soil in partial or dappled shade and protection from scorching winds. Tolerates sandstone and limestone soils but becomes chlorotic if the pH is too high. Prefers a pH between 6 and 6.5. A very variable species. It is normally an annual plant, but it is sometimes a short-lived perennial. A good bee plant. Grows well with rye but dislikes growing with wheat.
