Sweet Woodruff (Galium odoratum) is a shade garden delight, and the perfect groundcover for adding fragrance to your outside space while reducing lawn areas. Easily grown in average, medium to wet, well-drained soils, it’s fast growing, insect repellent, low maintainance, quick to establish and it isn’t prone to invasiveness — though you definitely do need to keep it in check. Sweet Woodruff has white spring flowers and an attractive eye-catching foilage. The foliage’s scent intensifies when the flowers are dried, which makes them a popular choice for those making potpourri.
