Agave plants are native to South America. Often referred to as a cactus, it is in fact not technically a member of the cacti family. It likes to dry up between waterings and is completely okay in a dry climate. And yes, this is the same tyoe of plant used to make tequila.
Care:
Water: You can water this as little as every 28 days in the winter, and increase frequency to about every 14 days in the summer. Make sure the soil dries up completely between watering.
Light: Make sure to put this in the brightest spot in your home. It won't do well in north-facing or obstructed windows.
Humidity: It doesn't require any humidity to thrive.
