Cyphosperma balansae

Cyphosperma balansae is a solitary pinnate palm native to central and northeastern New Caledonia, where it grows in wet forest at roughly 400–1,000 m. It can reach about 15 m and is notable for its upright crown and very long, arching inflorescences ([The Palms of New Caledonia](https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers21-02/010018798.pdf); [Kew POWO](https://powo.science.kew.org/taxon/666392-1)). ## Growing Conditions The species occurs on schist-derived and ultramafic soils in humid forest. Its natural setting suggests a warm, moist position with reliable drainage; retain moisture through active growth and avoid prolonged dry conditions ([The Palms of New Caledonia](https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers21-02/010018798.pdf)). Its upright leaves and extended inflorescences need open space as the palm matures. ## Landscape Use This is an uncommon palm in cultivation, valued for its unusual crown and long, arching flower clusters. It can serve as a specimen in a spacious tropical or subtropical garden where its form and inflorescences have room to show ([The Palms of New Caledonia](https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers21-02/010018798.pdf)). The reference notes that seeds germinate readily and seedlings are manageable, which can support propagation in cultivation rather than reliance on wild plants. ## Maintenance Keep the root zone moist but not waterlogged and protect the palm from cold. Give the crown room and remove only dead or damaged leaves. Because the species is uncommon in cultivation, source propagated plants from reputable growers and allow time for establishment ([The Palms of New Caledonia](https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers21-02/010018798.pdf)).
