what a strange plant.... Symplocarpus renifolius is a PERENNIAL growing to 0.5 m (1ft 8in). . It is in flower from Feb to April, and the seeds ripen from Aug to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects. Poisonous.
Pelican Flower (Aristolochia grandiflora) These flowers are almost beautiful in their strangeness, with big inflated chambers instead of petals and intricate, colorful patterns of veins. But don’t get too close, or you won’t be able to get the dead mouse smell out of your nose for hours. No, this plant isn’t a carnivorous rat-eater like the Nepenthes attenboroughii – it just uses a decaying rodent smell to attract pollinators.
