Lan Caihe (Chinese: 藍采和; pinyin: Lán Cǎihé; Wade–Giles: Lan Ts'ai-ho) is a Chinese mythological figure, and one of the Eight Immortals in the Taoist pantheon. Presence in the Eight makes this figure one of the more familiar out of hundreds of other Taoist immortals. Lan Caihe is the only one of the Eight Immortals whose gender is ambiguous. Lan isn't generally thought to be based on a historical person, but is traditionally said to have been born sometime during the Tang dynasty (618 to 907 CE), and lived as a homeless street entertainer, who wandered all over China, singing philosophical songs. Stories vary about how Lan attained immortality and became one of the Eight Immortals. Lan's emblem is a basket of flowers, and so this immortal is considered the patron of florists and gardeners.
