Tropicaleque without fear of frost
We're awfully spoiled here in northern California by the bay, where it seldom freezes, as even if it does, seldom drops below 25F at the worst. As a result, it is all too easy to create garden settings with lush subtropicals that can get huge over time. This side garden contains a 10 foot tall Tetrapanax papyrifera along with the foreground Asparagus retrofractus, as well as other more obscure South African tender shrubs such as Mackaya bella and Streptocarpella ground cover. Check out the other photos in the Flickr set for the rest of the garden, lots more tropicalesque plantings in a zone 8b/10a setting here in northern California across the bay from San Francisco.
