Lily – Spider

Hymenocallis is a wonderful genus of bulbous amaryllids…native mostly to the US, Mexico, and Central America. Hymenocallis (spider lilies) are an easy-to-grow moisture-lover that are a reliable perennial wildflower in the garden. Spider lilies are a tough, low maintenance plant which makes it perfect for rain gardens.

In the wild many Hymenocallis (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. try growing your spider lily next to dahlia, buddleia, sarracenia, sabatia, or hibiscus.

Note: The bulb is enormous! You need at least a 5 gallon container.
