Meadow-rue has beautiful, lacy foliage a little bit like a Columbine or Maidenhair Fern in effect. This species produces rather tall clumps, with deep purple stems that bear big clusters of bright lavender-mauve flowers in midsummer. Both the leaves and flowers are excellent for cutting. Terrific in the woodland garden, or in a moist sunny border.  This might need to be staked to prevent the plants from flopping over.  Zone 4-9.  Part Shade.  5-8' tall (8' in very rich soil!), 18-24" spread.  Quart Size pot
