Amorphophallus rivieri ‘Konjac’


Amorphophallus 'Konjac' forms an incredible red inflorescence with unmistakable "aroma" followed by gorgeous stems and foliage.

Amorphophallus 'Konjac' is a weird and wonderful plant from the Arum family grown from Indonesia to Japan for its edible tuber. Ornamentally, it is grown for the incredible 4-5” tall deep red, jack-in-the-pulpit-type inflorescence in spring, followed by the attractive and intriguing spotted stem and single large umbrella-like dissected leaf for the whole of summer. Sounds great, right? Here’s the clincher: you just have to make it through the few days in spring when the flower smells like rotting meat! It’s certainly FRAGRANT!
