Zamia — 25 species

Zamia is a genus of ancient cycads native to the Americas, including Florida Arrowroot (Zamia integrifolia) and several Central American species. They prefer bright, indirect to direct light and well-draining soil, allowing the mix to dry out between waterings — overwatering is the most common cause of decline. Growth is slow and architectural, making them striking container or landscape specimens in USDA zones 8b–11. All Zamia species are toxic to cats, dogs, and horses: they contain cycasin and related neurotoxins that can cause severe vomiting, liver failure, and death. Keep them entirely out of reach of pets and children.
