Begonia longiciliata (syn. Begonia sizemoreae) is a rhizomatous, subtropical “eyelash begonia” known for its dramatic leaf texture, long marginal hairs, and velvety, asymmetrical foliage. The short version: it’s a humidity‑loving understory plant from China, Laos, and Vietnam that thrives in bright filtered light, excellent airflow, and evenly moist—but never wet—soil.
