Old man cactus takes its name from the long, white hair-like strands which grow out of the spiked column that makes up the plant. The greater the intensity of the light the longer and thicker the hairs become.
Care:
- Light: Old Man Cactus love being close to bright, sunny windows. Place it less than 1ft from a south-facing window to maximize the potential for growth.
- Water: Allow the soil to dry out completely before watering
