Fairy Castle Cactus 3.25" Pot
This small, slow-growing variety has dark five-sided green stems studded with white spines. In time, and in ideal growing conditions, it can reach about 36 inches tall.
Light: The best place for most cactus houseplants is a warm, bright spot. These sun-lovers do best when they get lots of direct light.
Water: Wondering how much to water cacti? In general, you can water most types once every two or three weeks or so. If in doubt, it's usually best to water too little; cacti can rot if they stay too moist.
