Description

Native to the southeastern US, this spider lily is a herbaceous perennial that is grown from a bulb. It is the most cold hardy plant of the spider lilies.  The name is derived from the Greek words hymen (membrane) and kallos that translates to beauty.  These words allude to the membrane uniting the stamens.  

Resembling a daffodil with long, thin filaments, these showy, fragrant flowers sit at the top of the stems.  They can be found growing in moist fields, swamps and bottomlands.  

Each bulb can multiply to form a dense clump.

A low maintenance plant, removing the foliage after it turns yellow will aid in the appearance of the garden.  

It is sometimes used as a houseplant or interiorscape, but in its natural habitat it can be found in forest or natural area in marshes, shallow streams, and ditches. This plant was once found wild in NC but is now found only in the lower Mississippi Basin.

Insects, Diseases, and Other Plant Problems:  No serious issues, however mealy bugs, snails and caterpillars can damage the plant.  It can be poisonous to many animals.
