The stem of Amorphophallus konjac is very big. It blooms first and leaves will grow after the flowers wither. Huge inflorescences grow directly from tubers, many times higher than leaves. Amorphophallus konjac does not bloom every year. A leaf grows when it doesn't bloom. The leaves are so big that they can grow to six meters high and five meters wide. They are shaped like tree trunks, and each branch has some leaflets, so a leaf of the konjac corpse looks like a tree.
Amorphophallus konjac flower is famous all over the world, not only because of its peculiar appearance, but also because of its distinctive smell. Amorphophallus konjac will give off a strange smell of rotting corpses after it blooms, and it will aggravate the odor with the opening degree of the flowers. So some people think that the smell released by konjac flowers is toxic. However, studies have shown that the odor released by konjac flowers is not toxic, but only releases odor to attract flies and beetles that eat carrion to spread pollination.
Amorphophallus konjac flowers are nontoxic, and wild Amorphophallus konjac is on the verge of extinction. Although it is now partially cultivated artificially, it grows rapidly. Its flowering period is only 2 to 3 days, and it only blooms once every 7 years. Most people can't reach its flowering period. It stinks, just to attract some insects to spread pollen for themselves.
