aka Arum dracunulus has survived a Winter outdoor planting in Zone 5.

The plant is variously called the Dragon Arum, Voodoo Lily, Ragons, Snake Lily, Black Arum, Black Dragon, Dragonwort, & Stink Lily. Five plants eventually grew, and one is going to bloom soon. The spike on the larger plant is the blooming structure.

Early morning pictures and the flower was only partially open and later when the sun came out full, the bloom opened up, and now has a slight odour, and the flies are congregating. The plant odour attracts flies to assure pollination.
