Cultural Significance
Golden Chalice Vine is often called "Cup of Gold" for its massive, chalice-shaped golden flowers that resemble a golden goblet or ceremonial cup. The flowers release an intoxicating fragrance reminiscent of coconut, banana, and vanilla, especially at night. Despite its beauty and sweet scent, the plant is a member of the nightshade family (Solanaceae), related to Datura, and all parts contain toxic and potentially hallucinogenic compounds. The genus Solandra contains 8-10 species of woody vines from tropical Americas. The plant can grow to massive proportions, with some specimens reaching over 200 feet in length in ideal conditions. It symbolizes overwhelming beauty that commands respect and caution.Shop Our Floral Collection
