Fun Facts
- 🌱 The common name 'Toad Lily' comes from the spotted flowers resembling a toad's skin, though the nickname is somewhat misleading—the plant has no connection to actual toads and is entirely harmless.
- 🌱 Tricyrtis are sometimes called 'Japanese gems' and have been cultivated in Japanese gardens for centuries, valued for their late-season blooms when few other shade plants flower.
- 🌱 The 'x' in the cultivar name indicates this is a hybrid, created through deliberate cross-breeding to combine desirable traits from different Tricyrtis species into a single superior plant.
