Hymenocallis, a genus of plants in the family Amaryllidaceae
Hymenocallis is a wonderful genus of bulbous amaryllids...native mostly to the US, Mexico, and Central America. Hymenocallis (white spider lilies) are an easy-to-grow moisture-lover that are a reliable perennial wildflower in the garden. White Spider lily bulbs are tough and low maintenance making them perfect for rain gardens.
In the wild many Hymenocallis (white spider lilies) often grow in or near water or, in a seasonally flooded woodland. However, most hymenocallis perform just as well in an average garden soil. Hymenocallis produce unusual white, spider-like, nocturnally fragrant flowers that are large enough to see from quite a distance. Hymenocallis is definitely a "gotta have it" plant.
