Dypsis robusta

*Chrysalidocarpus robustus* is a large, solitary palm originally described from a cultivated plant in Hawaiʻi; it was published as *Dypsis robusta*. The 2022 taxonomic treatment transferred it to *Chrysalidocarpus*, and Kew lists the earlier name as a synonym. The described nursery specimen stood about 6 m tall overall, but few mature plants have been documented, so that figure is a reference rather than a guaranteed landscape maximum. [Original species description](https://palms.org/wp-content/uploads/2020/05/v49n3.pdf) · [2022 taxonomic treatment](https://onlinelibrary.wiley.com/doi/full/10.1002/tax.12797) · [Plants of the World Online](https://powo.science.kew.org/taxon/60439796-2) ## Form and landscape use This is a substantial specimen palm with a thick trunk and very large pinnate leaves. The original authors considered it suitable for parks, public spaces, and large gardens in tropical and warm-subtropical climates. Give it generous overhead and lateral clearance; its broad crown and heavy leaf bases are out of scale for a small courtyard. ## Climate and growing conditions The published description is based on a palm grown in a Hawaiian nursery, and the paper says its suitability in Mediterranean climates is unknown. Choose a warm site and avoid assuming that it will tolerate cool winters from a general palm-zone label. Cultivation accounts describe it growing in full sun after establishment and doing well in a mulched garden, but local performance should be assessed conservatively because mature specimens remain uncommon. ## Maintenance Maintain a clear area around the trunk and remove only dead or damaged leaves. Keep mulch away from direct contact with the trunk, and watch for cold or prolonged drought stress in warm-subtropical gardens.
