Astelia comprises a family of monocotyledonous flowering plants typically found in Australasian and Pacific regions. They often exhibit broad, sword-like leaves, which may be adaptations to their frequently moist or shady habitats. These plants frequently develop striking flower spikes that rise above the foliage, aiding in their pollination strategies. Astelia thrives under forest canopies, suggesting a resilience and adaptability to lower light conditions.
