Blue Woodruff (Asperula Orientalis Blue Surprise) - Blue Woodruff seeds are a planting favorite of many herb gardeners. Asperula Orientalis, also called Oriental Woodruff, blooms in late spring to early summer with fluffy, lavender-blue flowers. Its lance-shaped leaves are wonderfully scented, creating a lovely perfume that wafts through the garden. The Oriental Woodruff herb is a terrific companion plant for roses, shrubs and large perennials. It tolerates quite a bit of shade, does well in moist locations, and the flowers attract butterflies. A synonymous botanical name is Asperula azurea.
