While there’s a difference between cacti and succulents, they’re also closely related. “Cactus” denotes a botanical family. Succulents are a broader group referring to a type of plant included in several botanical families. While all cacti are considered to be succulents, there are succulents that are not cacti. Cacti are well known, even to those who have little interest in horticulture. Succulents have increased in popularity due to their low-maintenance care, making them an ideal choice for first-time plant owners.
