Tricyrtis lasiocarpa stretches the toad lily range from the Himalayas east through China, Korea, and Japan all the way to the Philippines, finding its niche in moist, shaded groves, forest edges, and the banks of streams and trails. The genus name telegraphs the flower's most distinctive feature: three swollen, sac-like nectaries at the base of the tepals, the humped architecture that gives Tricyrtis its Greek name. In this species, slightly twisted white tepals carry heavy reddish-purple spotting and a vivid yellow throat, creating a bloom that reads almost tropical in the autumn shade garden.

Growing 2 to 3 feet tall, this perennial performs best in semi-shaded spots with rich, slightly moist soil and good drainage. It is worth noting that each stem lives only a single season, with the next year's growth bud forming underground, so divisions must include that bud to succeed. Place it at the woodland edge, along a lightly shaded drainage channel, or wherever a late-season focal point is welcome. Deer leave it alone, bees are reliably drawn to the nectaries, and the blooms make surprisingly good cut flowers when brought inside.
