If you’re looking to add some unique cacti to your indoor collection, consider the “Bishop’s Cap” (Astrophytum myriostigma) and “Old Man Cactus” (Cephalocereus senilis). Both have fascinating appearances that stand out.
The Bishop’s Cap appreciates bright, indirect light and well-draining soil. It’s quite drought-tolerant, so let the soil dry out completely between waterings. In contrast, the Old Man Cactus has hair-like spines that give it its distinctive look. It needs bright light, mimicking a sunny windowsill, and similarly dry conditions between watering.
Both of these species can become conversation starters and add some variety to your collection. Enjoy exploring their care nuances!
