How to identify Poisonbulb (Crinum asiaticum)

Poisonbulb, also known as Giant crinum lily, Spider lily

Poisonbulb is distinguished by its robust, bulbous base and an assemblage of semi-succulent, light green, strap-shaped leaves that can reach lengths of approximately 4 feet (122 cm) and widths of 4 inches (10 cm). These leaves emerge in an elegant, semi-erect spiral rosette. The resilience of poisonbulb is exemplified by its fragrant white flower clusters, each supported on sturdy 2-foot-tall (60 cm) stalks. It exhibits a remarkable tolerance for a range of moisture conditions and can withstand cold temperatures down to around 20°F (-6°C).
