Outdoor verdict
Cardboard palm lives outside only in a mild winter, about 25F (USDA 9b+). A real freeze marks it. It can sit in a bright room if your winter is colder than that.
A stiff-leaf indoor cycad sold as a palm. It is not in the palm family. USDA 9b to 11 outdoors, toxic seeds, and a decent bright-room plant.
Cold hardiness
Survives about 25°F / -4°C. Outdoor range USDA 9b–11b. Hover or click a zone, state, or country. Click a state to open palms that grow there.
Highlighted USDA zones 9b–11b. Green countries can be grown outdoors.

Alaska and Hawaii are state outlines with their overall zone range. A country is painted if its mildest inhabited winter is at least one USDA step milder than this palm’s hardiness.
What it is confused with
Nurseries often mix this up with Sago palm (Cycas revoluta). Check the Latin on the tag.
Winter care
Drainage matters more than a blanket. Soil: Gritty / cactus mix. Water: Water when the top inch is dry (mesic to xeric). Wrapping does not buy an extra zone. If the winter is colder than the kill number, keep it in a pot.

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.
Growth Rate:
Slow.
Fruit and Flowering:
No fruit in the palm sense. Female cones make toxic orange-coated seeds. Keep them away from pets and kids.
Light Requirements:
Bright indirect to morning sun. Harsh inland afternoon sun can bleach indoor-grown leaves.
Water Requirements:
Even moisture in heat, then drier in winter. Do not stand it in a saucer.
Maintenance Level:
Low. Cut a ruined leaf at the base. Light feed in the growing season. Do not treat it like a thirsty majesty palm.
Common Diseases/Pests:
Scale and mealybugs, especially indoors. Rot from overwatering.
Plant Care:
Bright light, drainage, toxic-seed awareness. Outdoors in frost-mild gardens. Indoors as a stiff, slow specimen, not a parlor palm substitute.
Cardboard palm Frequently Asked Questions:
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.
