Genus guide

Cycas — 17 species

Cycas are ancient, slow-growing cycads that evoke a prehistoric grandeur — species such as Sago Palm (Cycas revoluta), Siamese Sago Palm, and Australian Cycad make striking architectural specimens indoors or in sheltered outdoor positions. They demand very bright light, ideally within a foot of a south-facing window, and should be watered sparingly every one to two weeks, allowing the soil to dry between waterings to prevent root rot. Every part of every Cycas species is severely toxic to cats and dogs — even one or two seeds can be fatal — so this genus must be kept completely out of reach of pets.

Cycas — frequently asked questions

Are Cycas plants toxic to cats and dogs?

Most Cycas are not pet-safe. Of the 17 Cycas species in the Growli library, 17 (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 Cycas plants need?

Most Cycas 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 Cycas easy to care for?

Cycas 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 Cycas varieties are there?

Growli's care library covers 17 Cycas species and varieties — browse them all above. They share a similar light, water and soil pattern, so once you learn one Cycas, the rest follow closely.
