The Spiderwort 'Concord Grape', Tradescantia ΅Concord Grape¦, has dark bluish-green foliage with purple flowers. The flowers open for one day but new blooms appear from June to October. The contrast of the flower color and foliage make it a definite eye catcher. ΅Concord Grape¦ mixes beautifully with wild and naturalistic woodlands, in any perennial bed or as a border plant and attracts butterflies. Try ΅Concord Grape¦ with Geranium ΅Johnson¦s Blue¦ or Alchemilla ΅Lady¦s Mantle¦.
