Tiarella cordifolia, commonly known as Foamflower, Heartleaf Foamflower, Heart-leaved Foamflower, False Miterwort, Coolwort, or Allegheny Foamflower, belongs to the Saxifragaceae family of plants. This herbaceous perennial is native to the cool woodlands of North America, where it thrives in the dappled shade and moist environments of its natural habitat.
The name Tiarella comes from Greek, referring to a crown-like structure resembling the effect of the seed capsules, while cordifolia, derived from Latin, describes the characteristic heart-shaped leaves of the plant. Tiarella cordifolia possesses horizontal rhizomes, which aid in its spread and colonization within suitable growing conditions.
The leaves of Tiarella cordifolia are a prominent feature of this plant. They are heart-shaped, adorned with fine hairs, and possess shallow lobes, giving them an intricate and delicate appearance. During the autumn season, these leaves transition to a captivating bronze color, providing a splendid display of fall foliage and adding visual interest to the landscape.
The flowers of Tiarella cordifolia grow on erect racemes, reaching heights of approximately 30cm or 12 inches. Each raceme bears numerous small, white blossoms consisting of five petals and approximately ten stamens. These charming flowers grace the plant from spring, typically from April to July, bringing a touch of elegance and allure to shaded garden areas.
After the flowering period, Tiarella cordifolia forms seed capsules. Each flower produces two seed capsules, varying in size, and encapsulating several seeds within them. This reproductive strategy ensures the potential for the plant’s expansion and the continuation of its lineage.
