Cardboard palm

Sun

Full sun to partial shade outdoors; bright light indoors. Acclimatise indoor-grown plants gradually before exposing them to direct sun.

Water

Water thoroughly, then let the upper few inches of soil dry before watering again. Water much less in cool weather; never leave the pot standing in water.

Soil

Sharply drained sandy or gritty soil. For containers, use a free-draining potting mix amended with pumice, perlite or coarse grit.

Height

2-4 ft (0.6-1.2 m)

Spread

4-6 ft (1.2-1.8 m)

Foliage

Evergreen. Arching, pinnate leaves with broad, leathery, dull-green leaflets. Young leaflets have rusty-brown hairs and feel stiff and rough, rather like cardboard.

Growth

Slow; established plants produce leaves in occasional flushes rather than continuously.

Care needed

Low

• Drought tolerant
• Heat tolerant

Northern hemisphere months. In Australia, shift them by six.

Growth rate

Slow

• Plant with the crown at its original soil level, in a position where water drains away quickly.
• Water deeply during active growth, allowing the upper soil to dry between waterings.
• Apply a slow-release fertiliser containing micronutrients in spring, following the label rate.
• Keep mulch clear of the crown and exposed stem.
• Move containers under cover before frost and keep them bright, relatively dry and frost-free over winter.

Pruning. Remove fully brown or damaged leaves at their bases with clean secateurs whenever needed. Leave healthy green leaves intact and never cut through the central growing point.

Spring

Check drainage and apply a slow-release fertiliser with micronutrients as growth resumes.

Late spring

Move overwintered containers outdoors once frost risk has passed, gradually increasing their exposure to sunlight.

Summer

Water when the upper soil has dried and inspect leaf undersides for scale insects and mealybugs.

Autumn

Reduce watering as temperatures fall and bring pots under cover before frost.

Winter

Keep sheltered plants in bright light and water sparingly, without allowing the root ball to remain wet.

• Use a single specimen in a broad, heavy container as a focal point on a sunny terrace.
• Repeat plants along a warm courtyard edge for a low, sculptural rhythm.
• Pair with agaves and aloes in a sharply drained gravel bed for contrasting leaf shapes.
• Place beneath taller palms in an open, lightly shaded tropical planting, allowing room for its spreading leaves.

Garden styles it suits: Architectural minimal, Modern tropical, Modern courtyard, Luxury resort, Dry gravel garden and Coastal.

Plant it with: Foxtail agave, Blue chalk sticks, Coral aloe and Ponytail palm.

Wildlife: In its native habitat, specialised beetles pollinate the cones. It offers little nectar or pollen value for typical garden pollinators; keep its poisonous seeds away from animals.

• Root or crown rot: usually follows waterlogged soil or excessive winter watering; improve drainage, reduce watering and repot affected container plants into fresh, free-draining mix.
• Scale insects and mealybugs: inspect leaf undersides and leaflet bases; remove small infestations by hand and use a labelled horticultural oil if needed.
• Frost damage: leaves may brown after freezing weather; move containers to shelter and wait until frost danger has passed before removing dead foliage.
• Sun scorch: sudden exposure to strong sun can bleach or brown leaves; introduce plants to outdoor sun gradually.

Highly toxic to people, cats, dogs and horses if eaten. All parts contain cycad toxins, with the seeds especially dangerous; ingestion can cause severe gastrointestinal illness, liver failure and death. Keep plants and fallen seeds away from children and animals, and seek urgent medical or veterinary advice after any suspected ingestion.

• Coontie (Zamia integrifolia)

  Coontie has much narrower, smoother leaflets, giving its leaves a finer texture than the broad, rough leaflets of cardboard palm.

• Sago palm (Cycas revoluta)

  Sago palm has numerous narrow, pointed leaflets with rolled-under edges, rather than broad, paddle-shaped leaflets.

• ZZ plant (Zamioculcas zamiifolia)

  ZZ plant has glossy, smooth leaflets on fleshy, upright leaf stalks; cardboard palm has matte, stiff, rough-textured leaflets and a woody cycad stem.

The common name describes the stiff, cardboard-like leaflets, while furfuracea means scurfy or bran-like, referring to their surface covering.

Propagation. Usually grown from fresh seed, which germinates slowly and needs warmth and a free-draining medium. Mature plants sometimes produce offsets that can be separated carefully, but establishment is slow and rot is a risk. Wear gloves when handling seeds and keep them away from children and pets.
