Tiarella cordifolia

Tiarella cordifolia (Foam Flower)

Tiarella cordifolia, or Foamflower, is a native perennial valued for its delicate beauty and versatility. This clump-forming plant features semi-glossy, heart-shaped leaves, accented by reddish veins. These details offer year-round interest, making it a charming choice for gardens. In spring, it produces tiny white flowers arranged in airy racemes, creating a frothy texture. The blossoms, held high on slender stems, add elegance to shaded spaces. Foamflower spreads efficiently by runners, forming dense colonies that work well as a groundcover for woodland settings or naturalized landscapes.

Thriving in USDA zones 4–9, Foamflower prefers part shade to full shade and humus-rich, moisture-retentive soils. It tolerates acidic conditions and adapts to heavy shade, which makes it suitable for challenging spots. Moreover, it is resistant to deer and rabbits, requiring little maintenance. Its blooms attract pollinators, adding ecological value to gardens. While it can endure brief droughts, consistent moisture is preferred for healthy growth. In colder months, the foliage often develops reddish-bronze tones, offering seasonal interest even in winter.

Care Instructions

• Light Requirements: Performs best in part shade to full shade, though morning sun is acceptable.
• Soil Needs: Prefers humus-rich, moisture-retentive soil and tolerates acidic conditions.
• Watering: Ensure the soil remains evenly moist but avoid overwatering.
• Spacing: Space plants 12–18 inches apart to encourage air circulation and healthy growth.
• Pruning: Remove spent blooms for neatness and cut back foliage in late winter if needed.
• Winter Care: Protect from overly wet conditions to prevent rot during colder months.

Foamflower combines charm, resilience, and ecological benefits, making it a perfect fit for shaded gardens. Its ability to thrive in tough areas, paired with its delicate blooms and attractive foliage, ensures it enhances landscapes with minimal effort. Whether used as a groundcover, border plant, or woodland accent, Foamflower provides year-round interest and functionality.
