Valerian has been used for centuries as a sedative and an aid to sleep. In the garden, its scented flowers draw butterflies, bees, and pollinators of all kinds. Herbalists prescribe it for agitation, pain, and insomnia. The lovely honey-scented flowers bloom in summer, appearing on tall stalks that shoot up from the low mat of green foliage. The roots are dug for use at the end of the 2nd year. Cats often have a strong reaction to valerian, sometimes using it like catnip. The seed should be planted as soon as possible, and will need a period of moist cold before sprouting, so pots are a good idea. You do not need to put it in a greenhouse or inside--just leave the pots out in the weather, and they will sprout as the days warm. 40 seeds.
