Native to arid regions, waltheria has evolved to thrive with minimal moisture, showcasing a high drought tolerance. Its water habits are balanced towards less frequent hydration needs, aligning with its ability to conserve water internally. For optimal care, watering should occur once every 2-3 weeks, ensuring the soil dries out between sessions. Typically grown outdoors due to its resilience and low-maintenance nature, waltheria is well-suited for xeriscaping—a landscaping method that reduces or eliminates the need for supplemental water from irrigation.
