Ladyfinger Cactus (Mammillaria Elongata)
Hardiness Level: The Ladyfinger Cactus is best suited for USDA Hardiness Zones 9-11. It can tolerate temperatures as low as 20°F (-6°C) for short periods but thrives in warmer, dry climates. This cactus prefers full sun to partial shade and requires well-draining soil to prevent root rot. Watering should be done sparingly, allowing the soil to dry out completely between waterings, especially during its winter dormancy.
