Ctenanthe burle-marxii

Botanical identity and natural origin of Ctenanthe burle-marxii

Ctenanthe burle-marxii is native to Espírito Santo in southeastern Brazil, where it grows in seasonally dry tropical habitats.

Care for a spreading Ctenanthe burle-marxii

• Watering: Keep the potting mix evenly moist while the plant is producing leaves. Water when the upper surface feels lightly dry, soaking the mix fully and letting surplus water drain.
• Light: Bright filtered light keeps the fishbone pattern clear and supports compact, leafy growth. If you add direct sun, begin with brief morning or evening exposure and increase it slowly.
• Pot and mix: A broad pot gives the spreading stems at the base room to extend. Use an airy organic mix with moisture-holding material, fine bark and pumice or perlite.
• Humidity and warmth: Moderate-to-high humidity helps the leaves stay flexible and supports healthy new growth. Keep this plant in a warm room with fairly even temperatures.
• Water quality: If your tap water is very hard, use rainwater or filtered water.
• Feeding: Feed lightly with a balanced fertiliser while the plant is actively growing. When growth slows, wait longer between feeds.
• Repotting and propagation: Repot when the rhizomes and roots have filled the available space. For propagation, divide along the rhizome, the horizontal stem at the base, so each section has healthy roots and several shoots.

What Ctenanthe burle-marxii symptoms can mean

• Leaves curling inward: Dry potting mix, very dry air, heat or root problems can curl the leaves. Check pot weight and moisture in the mix. A dry root ball needs a thorough watering. If the mix is still moist, check temperature, humidity, light and root health.
• Crisp tips or narrow brown margins: Repeated moisture swings, dry air and minerals or salts in the water can all contribute. Stabilise moisture and humidity, and flush visible mineral deposits with rainwater or filtered water.
• Yellowing while the mix stays wet: Excess moisture and root decay are likely when yellowing continues while the mix stays wet. Check that excess water can drain freely and let the mix lose some moisture. Inspect the roots if yellowing continues. Remove soft brown tissue with a clean disinfected tool back to firm healthy tissue, discard the decay and repot in fresh airy mix.
• Tiny grey speckles or fine webbing: Spider mites commonly settle on the lower leaf surface. Isolate the plant, rinse or wipe the foliage and use a treatment labelled for spider mites. Follow the repeat interval on the label.
• Cottony clusters at leaf joints: Mealybugs often hide where the leaf stalks meet the stems. Check these sheltered places. Remove visible insects and apply a treatment labelled for mealybugs. Use the label’s repeat interval for further applications.

When symptoms overlap, Foliage Factory support can suggest which check to start with.

Ctenanthe burle-marxii is non-toxic to cats and dogs

• This plant is non-toxic to cats and dogs.
• Its effects on people are unclear, so keep it away from young children who may chew it.
• Eating a large amount can still cause an upset stomach. Seek medical or veterinary advice if symptoms continue.

August Wilhelm Eichler established the genus Ctenanthe in 1884 in Abhandlungen der Königlichen Akademie der Wissenschaften zu Berlin, volume 1884, page 81.

Helen Kennedy first described Ctenanthe burle-marxii in 1982 in Canadian Journal of Botany, volume 60, page 2367.
