Every year in spring I receive a few hushed phone calls which usually begin “My “friend” has this strange plant blooming in her garden and she doesn't remember planting it.” I respond “You've got a case of Dragon Lily.” Emerging from a giant bulb like a mottled spear, the plant produces an upright, three foot stalk holding a few (often silver speckled) leaves. The stalk is topped with a lurid 18 inch burgundy spathe with a columnar purple-black spadix. It has an unpleasant “aroma” for a few days so don't plant near your front door. Goes dormant after flowering.

Open sunny fields, waste places, hill sides often in dry rocky soils.
