Caldwell Nursery in TX sends some of the nicest and biggest plants that I've ever received through the mail. They have mostly tropicals and bamboo. Plants marked as 1 gallon are the size of plants I've bought locally in 3 gallon containers. You have to call and make sure that they can ship a particular plant and many more are available than are listed on their website. Their customer service is great.
