Giant Window Palm

Giant Window Palm (*Beccariophoenix fenestralis*) is a solitary Madagascar palm whose young leaves show open “window” areas between leaflets that become more fully divided as the fronds mature. The [International Palm Society’s taxonomic description](https://palms.org/wp-content/uploads/2016/05/VOL58N2p57-64.pdf) documents this feature, and [Kew’s Plants of the World Online](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:77140441-1) recognizes the species. ## Landscape use Plant it as a dramatic specimen where a large palm can develop without crowding buildings or paths. A nursery listing gives a range of mature dimensions, so allow generous space for the crown. Published sources do not establish a precise hardiness threshold; provide warmth and protection from cold. ## Siting and soil Choose a warm position in full sun or partial shade with well-drained soil. Plantmark’s [nursery profile](https://www.plantmark.com.au/beccariophoenix-fenestralis) lists full sun to semi-shade and multiple well-drained soil textures. The species is native to Madagascar, but local humidity, wind and cold exposure can affect performance; avoid relying on an unverified single temperature threshold. ## Maintenance Water regularly during establishment and keep the root zone from drying severely while the palm is young. Maintain drainage, shelter young plants from drying winds, and avoid cutting healthy green fronds. Remove only dead leaves, using care around the crown and trunk.
