When to plant Foamflower 'Iron Butterfly'?

Tiarella 'Iron Butterfly' thrives in partial to full shade, making it ideal for woodland gardens, shaded borders, or beneath deciduous trees and shrubs. It dislikes hot, dry conditions and direct sun, which can scorch its attractive foliage. Choose a spot that remains cool and sheltered, particularly during summer. The soil should be moisture-retentive but well-drained, rich in organic matter. Loam or peat-based soils are ideal. Before planting, dig over the area and incorporate plenty of well-rotted compost or leaf mould to improve structure and fertility. If your soil is heavy clay, add grit or sharp sand to improve drainage; if it's sandy, work in extra organic matter to help retain moisture. Plant in March, April, September, or October when the soil is workable and temperatures are mild. Dig a hole slightly larger than the root ball, ensuring the crown of the plant sits level with the surrounding soil surface—planting too deep can lead to rot. Space plants 30 cm apart to allow for their eventual spread of 25–35 cm. After planting, water thoroughly to settle the soil around the roots and eliminate air pockets. Apply a 5 cm layer of organic mulch such as leaf mould, composted bark, or well-rotted compost around the base, keeping it clear of the crown itself. This mulch conserves moisture, suppresses weeds, and mimics the plant's natural woodland habitat. Keep the soil consistently moist during the first growing season to help the plant establish a strong root system.
