One of only two species in its genus, Calibanus hookeri is a member of the family Asparagaceae native to Tamaulipas in Mexico, which can easily be mistaken in the wild for a boulder overgrown with grass tufts.

Calibanus hookeri forms a large caudex which has been known to reach diameters and heights of up to 2.6 feet.

Atop the caudex sprouts extremely narrow greyish-green leaves that look like grass.

Each leaf rosette grown from the caudex is believed to be a vegetatively produced independent plant which dies after fruiting to be replaced by a new one.

Calibanus hookeri likes full sunlight and well drained and fertilized soils.
