Ethel M Botanical Cactus Garden, Desert botanical garden in Henderson, Nevada.
Ethel M Botanical Cactus Garden is a space holding over 300 species of cacti and succulents spread across four acres with carefully designed desert plantings. The grounds sit next to the Ethel M Chocolates factory and combine both locations into one visitor experience where nature and chocolate making meet.
The garden was established in 1981 by Forrest Edward Mars Sr., who named it after his mother Ethel Mars and built it alongside the family chocolate factory. The project grew from a business venture into a place where industrial operations and environmental stewardship merged from the start.
The name honors Ethel Mars, the founder's mother, and reflects a connection between chocolate making and desert plant conservation. You notice signs throughout explaining how plants survive here, and visitors naturally learn why water is so precious in this landscape.
The garden is free to visit year-round and easy to access without advance reservations needed. You can explore the paths on your own or join guided tours for a fee that can include the neighboring chocolate factory.
The site uses a living water treatment system where bacteria, algae, snails, and fish clean wastewater from the chocolate factory before it irrigates the garden. This biological filter works invisibly behind the scenes but demonstrates an innovative recycling approach that few visitors realize exists.
