Light: Morning sun with afternoon shade is best in Phoenix; avoid intense reflected heat and unfiltered afternoon sun.
Water: Water deeply, then let the upper several inches of soil dry before watering again. Established plants tolerate some drought but benefit from regular summer irrigation; reduce watering substantially in winter.
Soil: Well-drained sandy or loamy soil; avoid compacted soil, standing water, and planting the crown too deeply. Use a freely draining mix in containers.
Mature size: Typically 6–10 feet tall and 6–8 feet wide over many years; very old specimens can grow taller. #25 and 24-inch box refer to nursery stock sizes, not mature dimensions.
Bloom: Does not flower. Mature plants periodically produce reproductive structures, with male and female structures on separate plants.
Evergreen / deciduous: Evergreen.
Growth rate: Very slow; often produces only one flush of new fronds annually.
