This is the Peruvian Old Man cactus, Espositoa lanata, not to be confused with The Old Man cactus, Cephalocereus senilis. The old man cactus has stiffer "hairs" that stick out and give it a more unkempt appearance in contrast to the soft whispiness that surrounds the Peruvian Old Man cactus.
I spotted this sitting on the windowsill while visiting my friend and plant-appreciator, Suzy. at her house the other day. It is growing well in its own naturally amusing way. She's had for a long time in great light and allows it to dry out thoroughly before watering it.That's the recipe for successful cacti growing!
This living wonder with its snow-white cottony hair is indigenous to Columbia and Peru. It will eventually grow to about 3 ft. (or 1 meter) high. I will have to remember remember to let Suzy know that.
- Direct sun.
- Water when dry 1" (about 2-3 cm) below the soil surface for plants in a 6" (15 cm) diameter pot.
- Water when dry about 2" (5 cm) below the soil surface in an 8" (20 cm) diameter pot.
- A moisture meter for indoor plants van be a great way to monitor when your plant will need water. The meters should be easy to find online or at your nearest garden center.
- It is tolerant of drying out more, if you should forget.
- Fertilize occasionally.
