It is going to be difficult to gauge what a palm will do. The areca is a clumper and you can never tell which direction it will go. Also the rate of growth can vary depending on soil, water and fertilizer. There are a lot of other palms that will make great hedges,and can add a lot of color at the same time. Contact the Hawaii Palm Society as they have a list of nurseries that can help you.
