• Indoor and Patio Planting: When young, this palm can be grown in large containers and used for indoor decoration or on patios. Its attractive fronds and symmetrical growth make it popular for large indoor spaces such as atriums and lobbies.
• Shade Provider: Due to its height and large fronds, the Alexandra Palm provides shade in gardens, parks, and along walkways. Its broad canopy offers relief from the sun and enhances the aesthetic appeal of outdoor spaces.
• Wind Resistance: This palm is relatively wind-resistant, making it suitable for planting in areas prone to tropical storms or in coastal regions where wind can be a challenge for other plants.
• Wildlife Habitat: The Alexandra Palm produces small fruits that are attractive to birds and other wildlife, providing food and habitat for various species. Its presence in gardens helps support local biodiversity.
• Erosion Control: The palm’s root system helps to stabilize soil, making it a good choice for erosion control in areas with slopes or where soil movement is a concern.
• Urban and Commercial Landscaping: Its elegant form and fast growth make it a popular choice for urban landscaping projects, such as in shopping centers, resorts, and public spaces, where a tropical feel is desired.

These uses make Archontophoenix alexandrae a versatile and popular choice for landscaping, particularly in areas where a tropical, lush aesthetic is needed, along with functional benefits like shade, wind resistance, and wildlife support.
