Fun Facts
- 🌱 Schizostylis gets its common name 'Kaffir Lily' from its South African origin, though the term is considered outdated; it is now often called 'Crimson Flag' or 'River Lily' to reflect its native habitat along river banks.
- 🌱 The plant's scientific name Schizostylis literally means 'split style,' referring to the distinctive divided stigma (female reproductive part) of its flowers.
- 🌱 Schizostylis is one of the last garden perennials to flower, often blooming well into November and December in temperate climates, providing valuable late-season color when most other flowers have faded.
