The golden fruit palm, also known as the areca palm ( Dypsis lutescens ), is a plant species from the palm family (Arecaceae) native to Madagascar . It is a common houseplant.
features
The golden fruit palm is multi-stemmed, the stems can reach a height of over 8 m and a diameter of 5 to 7.5 cm. The younger sections of the trunk are dark green to yellow or orange, depending on the exposure: with high light intensity the trunk turns yellow. The rings of the leaf scars are arranged relatively close together. The crown is up to four meters wide and 3.3 meters high. A fully grown trunk group can reach a height of 12 m and a width of 6.5 m. The crown shaft is around one meter long, grayish green to almost silver gray and slightly expanded at the base.
The leaves of adult specimens are 1.8 to 2.4 m long, narrowly ovate and curved sickle-shaped. The leaf stalks are 60 cm long, as are the thin and narrow-lanceolate, yellow-green to dark green leaflets. These stand at a 40 ° angle from the rachis and thus form a distinct V-shape of the leaf blade . The petiole and rhachis are light green to almost orange, also depending on the light intensity. The leaves move in the lightest wind. The crown consists of six to eight leaves.
The inflorescence stalks are pendulous, branched and arise below the crown shaft. The flowers are yellow. The fruits are egg-shaped, 2.5 cm long and yellow-orange to purple or black.
Distribution and locations
The species is endemic to eastern Madagascar. It grows on the sandy river banks and in clearings of the wet forests. Their area is small and spread over several isolated locations that are endangered by the expansion of agriculture. The species is therefore critically endangered .
use
The golden fruit palm is often planted outdoors as an ornamental plant in tropical areas . It is sensitive to the cold and only grows outdoors in USDA 10b and 11 climates without being harmed. Due to its rapid growth and multi-stemmed structure, it survives even in zone 10a with frost damage. It is insensitive to the type of soil as long as the soil is well permeable to water. It needs a lot of water and light.
It is also one of the most common houseplants , needs a lot of light and is often attacked by spider mites when it is dry .
So-called "palm leather" can be made from the bark.
Systematics
The species was first described in 1878 by the German botanist Hermann Wendland as Chrysalidocarpus lutescens . Like some other Malagasy genera, the monotypical genus Chrysalidocarpus was placed in the genus Dypsis by Henk Jaap Beentje and John Dransfield in their work Palms of Madagascar in 1995 , with the name Dypsis lutescens . In gardening circles the palm is also carried under the name Areca lutescens , which however is not a valid synonym.
