gloriosa

Gloriosa is a genus of flowering plants in the family Colchicaceae. It comprises several species of herbaceous, tuberous climbers native to tropical Africa and Asia. Plants grow as twining vines with simple, glossy leaves and a slender tendril at the leaf tip that helps them climb. The flowers are solitary, pendant, and highly distinctive: three petal-like tepals that are usually reflexed and curling backward, creating a flame-like silhouette.

The best known species is Gloriosa superba, commonly called flame lily or gloriosa lily. Other species include Gloriosa simplex and Gloriosa rothschildiana. Flower color ranges from red to orange to yellow, often with a contrasting yellow or greenish center; cultivars exist with various patterns.

Toxicity and uses: All parts contain toxic alkaloids, most notably colchicine; ingestion can cause severe irritation, organ injury, or death in humans and animals. Colchicine extracted from Gloriosa has been used in medicine and plant breeding, but commercial use generally relies on other sources or synthetic processes.

Cultivation: Gloriosa thrives in warm climates and is cultivated as an ornamental plant in gardens and containers; it prefers well-drained soil, regular moisture during the growing season, and bright but indirect light. It tolerates some sun depending on climate. The plant goes dormant in dry seasons; tubers can be lifted and stored in temperate regions; propagation is by seeds or division of tubers. It is often grown as an annual in cooler regions or as a perennial in frost-free areas.
