Tiarellas have added a whole new dimension of striking foliage to the shade garden. ‘Iron Butterfly’ is a particularly good Tiarella with large, bold contrasting foliage in inky slate edged with bright green. Stunning as a mass planting, ideal to mix and match with hostas or combine it with new Heucheras such as Obsidian for the effective use of black to highlight and complement the foliage of this Tiarella. Ideal also for cut flower foliage for bringing interest indoors. Tiarella ‘Iron Butterfly’ has the bonus of large fragrant flower heads in spring.  Water and feed occasionally with slow release fertiliser. Allow to dry out slightly between waterings. Likes rich soils with good organic matter content
