This red-veined dock is a conversation starter! Easily grown in average, medium moisture, well-drained soil in full sun. Best performance is with consistently moist soils. Soils must not be allowed to dry out. Self-seeds and can be invasive in the garden. Some gardeners prefer to remove the flower stalks immediately both to prevent self-seeding and to promote bushy leaf growth. Leaves often lose sharp leaf and stem coloration as they age and may be trimmed off to promote growth on new leaves. Plants are reportedly winter hardy to USDA Zone 6, but have survived winters in Zones 4 and 5. Plants may be directly seeded in the garden in spring. May be grown as an annual. Propagate by seed or division.
