Fairy Castle Cactus
This very cool cactus is a great way to introduce kids to the joy of plants.
The name comes from the numerous vertical stems of different heights that resemble spires and turrets.
Place indoors where it will get early morning sun, or on the patio with filtered shade (and protected from freezing temperatures), water occasionally, (when completely dry) and watch the “castle” grow.
Rotate the pot every few months to keep it from growing crookedly toward the light.
