Comments: This is a tall stately growing palm that produces huge stiff fronds that leave stubs along the trunk after they fall. Cotton like threads are present along the edges of the leaflets. The leaf stems produce heavy stiff thorns along the stems. Palms can withstand the shock of being transplanted in very large sizes. Provide full sunlight and well drained soils for palms.
