Succulents make great houseplants because they are attractive, grow slowly, and are not frequently bothered by insects. Spineless Agave, or Agave attenuata, is a particularly nice plant to grow in the home. It can be found sold as Spineless Agave, Foxtail Agave or Dragon-Tree Agave.
Spineless Agave grows in a rosette like virtually all succulents. It is an attractive shade of chartreuse, making it a lovely accent plant. As the plant ages and old leaves senesce, or die off, a sort of trunk forms giving the plant height. It can reach up to 6 feet outdoors, but expect it to grow much more slowly and stay smaller indoors.
Provide your Spineless Agave with bountiful light, but protect it from hot direct sun. It cannot handle midday sun outdoors in its native environment in zone 9. In cooler climates, especially with a window pane breaking the sun a little, bright sun all day is not likely do any damage. Make sure to provide at least a few hours of direct sun daily. If direct sun cannot be provided, bright diffuse light will do.
Keep your Spineless Agave in a pot that seems somewhat too small for it and use a medium that is designed for cacti and succulents. Depending on the temperature and amount of light your plant receives, it could need to be watered every couple of days or only every couple of weeks. You should allow the potting mix to dry out almost completely before watering again.
Spineless Agave is best propagated by division. You can separate the rhizomes into individual plants and pot them up separately or in groups, with or without other succulents or cacti. Strawberry planters can also be used to create some interest, as they are available in every color imaginable.
