little old ant rubber tree plant Hydnophytum papuanum "Ant Plant"Hydnophytum papuanum "Ant Plant", commonly referred to as "Maze Plant" after its corridor system inside the caudex (swollen trunk). In its native habitat they live in symbiosis with ants, providing them with a home in exchange for nutrients from their excrement and in turn the ants defend the plant against any threats from pests and predators! [As a Note, that doesn't mean they attract ants! That is just how they live in the wild.] Hydnophytum

Hydnophytum papuanum "Ant Plant", commonly referred to as "Maze Plant" after its corridor system inside the caudex (swollen trunk). In its native habitat they live in symbiosis with ants, providing them with a home in exchange for nutrients from their excrement and in turn the ants defend the plant against any threats from pests and predators! [As a Note, that doesn't mean they attract ants! That is just how they live in the wild.]

Hydnophytum papuanum as a species has been combined with and is now technically known as Hydnophytum moseleyanum. 

Loves high humidity, where it can draw moisture from the air. Grows best when watered regularly, soil should be kept slightly damp, never wet as it is susceptible to rot. Indirect bright light is preferable, will tolerate lower light levels but growth will be much slower.  Since there are no ants to deposit excrement inside the tuber, fertilize during the growing season with a liquid houseplant fertilizer.
