Silver Thatch Palm

Silver Thatch Palm in this record is Clinostigma warburgii, an accepted palm species native to Samoa and especially associated with ‘Upolu’s wet tropical biome. The name and scientific identity stay tied to this species; Kew places it in Arecaceae, while a palm-grower reference describes its solitary trunk, green crownshaft and arching pinnate leaves. [Kew Plants of the World Online](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:666015-1) and [Palmpedia’s Clinostigma warburgii profile](https://www.palmpedia.net/wiki/Clinostigma_warburgii) provide the taxonomic and horticultural details. ## Landscape Use This is a tall, tropical foliage palm suited to spacious warm-climate landscapes or specialist tropical collections. Its upright trunk and broad, arching crown give it a strong vertical presence; allow room around the crown and mature trunk rather than treating it as a small understory palm. The grower profile describes humid-tropical cultivation and fast growth, and reports USDA hardiness from zone 11 upward. Those details apply to Clinostigma warburgii and should not be generalized to other palms sold under similar common names. ## Growing Conditions Choose a humid, frost-free setting that reflects its wet-tropical origin. Kew records the species as native to Samoa and growing primarily in a wet tropical biome. Protect it from cold exposure and provide space for its eventual palm form; the available sources do not establish a compact mature width for this species. ## Maintenance Keep the growing site warm and humid, and monitor the root zone so it does not dry sharply between waterings. Remove only dead or damaged foliage, using appropriate palm-care practices for the plant’s size. [Palmpedia](https://www.palmpedia.net/wiki/Clinostigma_warburgii) describes the species as fast-growing in humid tropical cultivation.
