About

Aristolochia fimbriata is a unique herbaceous perennial known for its sprawling growth habit, often weaving through the surrounding vegetation. The plant features rounded, heart-shaped leaves that are prominently veined in silver. During early summer, it produces elongated pale green flowers characterized by a brown throat and a bulbous opening adorned with a checkered brown pattern and long, fringed hairs. The flowers emit a strong odor to attract flies for pollination. Once pollinated, the plant develops large, pale brown seed pods that expand into lantern-like shapes as they mature and dry.
