Easily grown in average, acidic, dry to medium moisture, well-drained soils in part shade to full shade. Prefers loose, organically rich loams with consistent moisture in part shade (sun-dappled or morning sun). Foliage will usually burn in full afternoon sun. Tolerates full shade. Also tolerates drought and dry shade (rhizomes hold moisture) once established. Intolerant of alkaline soils. Clumps spread somewhat slowly but will form attractive colonies over time. E. grandiflorum is deciduous in USDA Zones 5-6. Although sometimes semi-evergreen south of Zone 6, foliage still tends to disappear on its own by spring. Any foliage that does survive winter should be cut back in late winter prior to emergence of new growth. Propagate by division in early spring or fall.
