Asperula ( Blue Woodruff ) Seed

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 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.

Useful gardening information

How To Grow Blue Woodruff: Start seeds indoors in the late winter for transplanting out in the spring. Or, many gardeners recommend sowing the herbs seeds directly outdoors in prepared seedbeds several weeks before the end of frost season. The seeds germinate better in cooler temperatures. The plant does not perform well in extremely hot weather, so it may not survive the hottest weeks of summer. In cooler regions, the plant continues to look and smell fresh right up until frost. Blue Woodruff is one herb plant that reliably re-seeds itself for another year of blooming.
