Additional comments: In the landscape, this is a MASSIVE palm that is not for the faint of heart and is too large for most residental landscape spaces. Otherwise, Canary Island date palm can be maintained in large tub containers for years as small accent palm that looks like the top of a pineapple. But plant it in the ground and as Keith Jackson says, "Whoa Nellie!!", there it grows (here's P. canariensis in Santa Barbara, CA).
