Why grow agave? Well, these low-maintenance plants can add beauty with their stunning foliage in both your indoor houseplant collection and your outdoor landscaping. Plus, most varieties will flower at least once in their lifetime. Growing both indoors and outdoors has its pros and cons.
For growing indoors, you’ll want to choose small, compact varieties that do well in containers. You won’t need to give any consideration to your growing zone or climate because indoors, you can create the perfect conditions. Indoors, they prefer a bright, sunny window and need to dry out completely between waterings.
For growing agave outdoors, mature size does not matter as much. Since you don’t have to contain the plants in a pot, you can choose varieties with a wide range of mature sizes. Some can reach up to 10 feet tall and wide when grown outdoors. For outdoor plants, you’ll need to consider your USDA growing zone and whether or not it will get too cold for these outdoor plants to survive.
Indoor Varieties
As mentioned above, agave varieties that do well indoors consist of small and compact varieties. These varieties may be pint-sized, but they aren’t short on beauty. Each variety has its own unique foliage, and they’re perfectly suited for life on a windowsill.
Agaves do not require much in terms of care for a houseplant. Watering them too often or fertilizing them can cause them to die. If you often find yourself forgetting to water your houseplants, then agave might be the plant for you!
When growing indoors, you want to choose a container with a drainage hole, but ditch the saucer as you don’t want to create any standing water. Overly moist soil can be detrimental. And while these varieties are perfect for indoors, you can grow most of them outdoors, too!

Outdoor Varieties
When selecting an agave variety to grow outdoors, you’ll need to consider your USDA growing zone. Here, we’ll include that information with each variety so that you can decide if it will grow outdoors in your area. The growing zone indicates the average low temperature in your area. This is important to know for multi-annual plants like agave since they will be spending the winter outside.
Agaves are native to the Southern United States, Central Mexico, the Caribbean, and parts of South America. For this reason, they grow best in Southwest and Mediterranean climates, but some are quite cold and hardy. To survive the winter, like most agaves, they will need well-drained soil. Standing water in colder months can cause damage and plant death.
