Red Spider Lily

The red spider lily is a perennial bulb that blooms in late August or September. A single stem emerges out of the ground unexpectedly and within days reaches a foot tall. The bloom opens a spidery look with long filaments that leave the center of the bloom, dip a little, and come up again with distinctive anthers and surrounded by modified petals.
