What plant takes 10 years to grow?
In cultivation, the titan arum generally requires five to ten years of vegetative growth before blooming for the first time. Titan arums don’t flower often—whether in the wild or at botanic gardens. A native of the equatorial rainforests on the island of Sumatra (in the Indonesian archipelago), Amorphophallus titanum takes its time to grow before blooming—often ten years or more.
