Additional comments: Windmill palm is rarely seen in Phoenix, even though it is a good palm choice for use around pools, water features or as a taller accent plant for smaller, protected landscape spots (it is a Phoenix landscape wimp). The only caveat to its use is that our local low relative humidities and intense sunlight facilitates an unsightly tattering (dessication) of the frond pinna tips.
