Fun Facts
- 🌱 Tricyrtis means 'three-humped' in Greek, referring to the three bumpy protrusions at the base of the flower's lip, which give these flowers an exotic, almost orchid-like appearance.
- 🌱 Toad lilies are called 'Tojen' or similar names in Japan because their spotted flowers resemble toad skin, and they naturally grow in cool, moist woodland habitats.
- 🌱 This plant is a favorite of late-season butterflies and bees because it blooms when few other shade plants are flowering, making it invaluable for supporting pollinators into fall.
