Swamp leather-flower (Clematis crispa)
Click on terms for botanical definitions.
Swamp leather-flower is a climbing or trailing perennialvine. Its distinct nodding flowers are pinkish-purple and mildly fragrant. No petals are present, but the four petal-like sepals are fused at the base, giving the bloom a bell- or urn-like shape. The sepals separate and become revolute as the flower opens. Sepal margins are thin and undulate. Flowers are solitary and born on naked, angled stems. Leaves are pinnatelycompound, oppositely arranged, and usually have 3 to 5 leaflets. Fruits are achenes with long conspicuous awns.
Swamp leather-flower occurs naturally in floodplain forests, wet hammocks and riverine swamps. Flowers typically bloom in spring and summer, attracting a variety of pollinators. The seeds provide food for many birds and small wildlife.
The genus name Clematis is from the Greek clématis, or “climbing plant.” The common name leather-flower refers to the flower’s fleshy sepals. Clematis crispa is also known by the common names Curly Clematis, Curlflower, Curly virgin’s bower, (all referring to the curled-back sepals), and Marsh Clematis.
