Seed or tuber.
don't those stink like poop??
The smell is more akin to rotting meat. However, this depends on which species of voodoo lily, your sense of smell, if it is being grown indoors or out (outdoors is recommended), & other little factors. I own 3 varieties. Mine are not so bad. You have to stick your nose directly in them & take a deep breath to know what they smell like.
Ohhh. I think they look neat!
I can get those. I grow them. I have bulbs.
