I am slowly converting my mixed perennial garden into a dedicated tropical garden. I find it challenging to use only (or mostly) tropicalesk plants and still have a visually appealing design. Bananas make it easy as they are a nice (and fast) anchor, but I don't want a banana in every bed...I also have used eucalyptus for this purpose. Any suggestions of combination plantings for some of my other beds that won't look like a reproduction of this bed? I've used banana, eucyalyptus, miscanthus, alocasia, phormuium, bamboo, and cannas, with a palm in the foreground.
