Yucca elephantipes Syn. Yucca guatemalensis is a large succulent with green leaves that are long, look like swords, and stick out from the tops of multi-stemmed trunks.
The plant can grow either indoors (where it will grow to be about 10 feet (3 m) tall) or outdoors in USDA zones 9 to 10.

The plant belongs to the Asparagaceae family, and is native to the regions between Mexico and Guatemala.
People like to grow them because of their bold and striking appearance in modern homes and gardens.
Yucca elephantipes needs to be planted in an area where it can access at least eight hours of full sun every day.

Because the roots can grow up to 20 feet (6 m) deep, they need to be planted away from any buildings.
Plant your Spineless yucca in well-draining soil, which can be created with the addition of sand. This will help to avoid potential root rot and fungal problems.
Do not overwater. Water the soil rather than the plant, and the soil should completely dry before watering again. Avoid watering in the winter.
The Yucca needs to be fertilized during the growing season, which is typically during the months of April to September where it is native.
Do not over-fertilize, and keep an eye out for pests, especially scale. If scale does occur, scrape off the brown spots with a toothbrush and pat with an insecticidal soap.
If this type of Yucca plant is grown indoors, contain in a pot no larger than 17 inches (43 cm) in diameter to prevent its growth.
Plants can be moved outdoors in warm climates where it will do well in the summer season.
