Full care guide
The cardboard palm is a Mexican cycad with stiff, felty leaflets, sold as a palm and as a small sago cousin. It is Zamia furfuracea, not Arecaceae. USDA 9b to 11 outdoors. Indoors it wants bright light and a mix that drains. The seeds are toxic.

Cardboard palm, cardboard cycad. It is not Jamaican sago in the Cycas sense.
Scientific Name:
Zamia furfuracea L.f.

Usually 2 to 4 feet in a pot or small garden bed. Width is the planning number.

Cold Hardiness and Hardiness Zone:
USDA 9b to 11. Damage in the mid-20s F. Not a zone 8 landscape plant.

Cardboard palm Frequently Asked Questions:
1. Is cardboard palm a real palm?
No. It is a cycad, Zamia furfuracea, related to sago. Palms are Arecaceae.
2. Is it toxic?
Yes. Cycad seeds and stems are poisonous if chewed. Same family warning as sago.
3. Cardboard palm or sago?
Sago is Cycas revoluta, usually a stiffer, more classic cycad trunk. Cardboard is lower, with broader, feltier leaflets.
4. Can it stay indoors?
Yes, in a bright room. It will not thrive in a dark hallway.
If you want a stiff indoor cycad sold as a palm, cardboard palm is that plant. If you want a true palm, pick Arecaceae. If you have pets that chew, skip the cycads.
