Genus guide
Ceratozamia — 12 species
Part of the Cycads family (Cycadophyta)
Ceratozamia is a genus of Mexican and Central American cycads — ancient, slow-growing plants with arching, pinnate fronds that give them an unmistakable prehistoric look. Indoors or in containers they do best in bright, filtered light and should be shielded from intense direct sun, which can scorch leaves. Water deeply when the top inch of the substrate dries out, then allow the mix to drain fully; reduce to roughly monthly in winter. All Ceratozamia species contain cycasin and are toxic to cats and dogs — ingestion can cause liver failure and is potentially fatal.

Ceratozamia — frequently asked questions
Are Ceratozamia plants toxic to cats and dogs?
Most Ceratozamia are not pet-safe. Of the 12 Ceratozamia species in the Growli library, 12 (100%) carry a toxic or mildly-toxic ASPCA classification and 0 are pet-safe. Always confirm the exact species on its pet-safety page before trusting it around cats or dogs.
How much light do Ceratozamia plants need?
Most Ceratozamia do best in bright indirect light. If yours stretches toward the window or loses its variegation it wants more light; scorched or bleached leaves mean it is getting too much direct sun.
Are Ceratozamia easy to care for?
Ceratozamia are moderate to grow: the main requirement is a genuinely bright spot out of harsh midday sun. Get the light right and the rest of their care follows.
How many Ceratozamia varieties are there?
