Chrysalidocarpus lutescens, also known by its synonym Dypsis lutescens[1] and as golden cane palm, areca palm, yellow palm, butterfly palm, or bamboo palm,[2] is a species of flowering plant in the family Arecaceae, native to Madagascar and naturalized in the Andaman Islands, Thailand, Vietnam, Réunion, El Salvador, Cuba, Puerto Rico, the Canary Islands, southern Florida, Haiti, the Dominican Republic, Jamaica, the Leeward Islands and the Leeward Antilles.[1] Its native names are rehazo and lafahazo (from Malagasy hazo 'tree' with reha 'pride' and lafa 'fibre' respectively).[3] [4]
Chrysalidocarpus lutescens is a perennial tropical plant that grows to 6- in height and spreads from 3-5 m (8-15ft). Multiple cane-like stems emerge from the base, creating a vase-like shape. The leaves are upward-arching, 2- long, pinnate, with a yellow mid-rib. The petiole is yellow-green in colour and waxy in texture, with a maculate base. The leaves have 40-60 pairs of leaflets. Leaflet arrangement is opposite and their shape is linear to lanceolate. It bears 2-ft-long panicles of yellow flowers in summer. Offsets can be cut off when mature enough, as a propagation method. It bears oblong fruit that is 0.5 in long and ripens from yellow/gold to dark purple/black. [5]
It is grown as an ornamental plant in gardens in tropical and subtropical regions, and elsewhere indoors as a houseplant, one of the most important commercially. It has gained the Royal Horticultural Society's Award of Garden Merit.[6] [7]
One of several common names, "butterfly palm", refers to the leaves, which curve upwards in multiple stems to create a butterfly look.[8]
In its introduced range, this plant acts as a supplier of fruit to some bird species that feed on it opportunistically, such as Pitangus sulphuratus, Coereba flaveola, and Thraupis sayaca species in Brazil.[9]
In its native habitat of Madagascar, C. lutescens grows in moist forested areas.[10] It grows best in rich, moist, and well-drained soils and in bright, partly shaded areas. It tolerates full sun, but long periods of direct sunlight may burn the foliage. Overfertilization results in yellowing of the leaves. It is a low-maintenance tropical plant.
It is winter hardy to USDA zones 10-11, and does well outdoors in warm climates with medium to high humidity. The plant is highly sensitive to cold temperatures.
C. lutescens has no serious insect or disease problems. It is susceptible to scale, whiteflies, and spider mites. Plants grown outdoors may be subject to phytoplasma disease of palms, which is spread by planthoppers and can cause severe yellowing.
In its native climate, the plant may be massed and used as a landscape specimen, privacy screen, or informal hedge. It can be grown as a tree or shrub. In areas of eastern Madagascar, this plant also has environmental and medicinal uses.[11] It is once used as a source of fibre to make fishing nets.
Chrysalidocarpus lutescens is a popular, low-maintenance houseplant. If grown indoors, plant in a well-drained potting soil in a pot that has adequate drainage holes. The size of the pot should be twice the size of the root ball. Repotting may be necessary every 2-3 years, and size of the pot should only increase 3-4 inches compared to the size of the old pot.[12] Ensure the plant is placed in an area with bright, indirect sunlight. It will thrive near a window where light is filtered, but will struggle if placed in the path of direct sun, which may cause scorching or yellowing of the foliage. If grown in areas with extreme temperatures, note that the plant will struggle in temperatures that drop below 60°F/15°C.[13]
This plant prefers moist soil, but cannot tolerate soggy conditions. To prevent overwatering, check the moisture level regularly and allow soil to dry out between waterings. The plant will benefit from fertilization in the summer months when it is experiencing the most growth. C. lutescens prefers medium to high humidity, if the air indoors is too dry, the foliage may exhibit browning at the tips. This can be remedied with manual misting or adding a humidifier to the room.
This plant does not require pruning. Pruning may be done based on owner preference.
