Loves as much bright light as you can give it. A south-facing window is ideal indoors. It will survive lower light but grows very slowly and may develop weak, leggy growth. direct sun (right in the window where sun actually hits the leaves. A strong grow light 4-6 inches away can substitute) through glass is generally fine.Light

Allow the top 2.5 cm (1 inch) of soil to dry before watering - in practice this means watering every 10-14 days in warm months and even less in winter. It is much more forgiving of underwatering than overwatering. Root rot from wet soil is by far the most common way these plants die indoors.Water

Tolerates dry indoor air without complaint. No humidity adjustments needed.Humidity

Thrives between 15-32°C (60-90°F) and handles temperature variation well. It can tolerate brief dips near freezing, but prolonged cold damages the foliage.Temperature

Spineless Yucca

Yucca gigantea

Easy

The Spineless Yucca is the yucca you can actually walk past without injury - its sword-shaped leaves are soft-tipped rather than needle-sharp, making it the sensible choice for indoor spaces with foot traffic. Mature plants develop thick, textured, elephant-leg-like trunks (which explains the now-defunct species name elephantipes) and can reach tree-like proportions over many years. It is a genuinely low-maintenance plant that tolerates drought, low humidity, and neglect better than most houseplants.

Did You Know

Fun Facts

The species name elephantipes refers to the thick, wrinkled base of mature trunks, which genuinely resembles an elephant's foot - a feature that takes years to develop indoors but becomes a striking sculptural element in large specimen plants.

Pet Safety

Toxic to pets

Toxic to cats, dogs, and horses according to the ASPCA. The toxic agent is saponins, which cause vomiting and diarrhea in cats and dogs, and dermatitis and potential liver disease in horses. Keep out of reach of pets.
