In the islands we have our own traditional Christmas trees. A dried century plant blossom has long been a favorite.
You can see pictures of it here, including one that has been decorated.
Some people spray paint the blossom white or silver or gold. I remember one year at our guest house at Lille Maho my grandmother cut down paper cups and attached them to a century plant blossom she set up at one end of the large porch of the main house. She filled the cups with sugar, attracting a small bird called the bananaquit. Bananaquits LOVE sugar.
They came by the hundreds (or seemed to) bringing with them their noisy, gregarious natures. Never before or since have I seen a Christmas tree with living ornaments.
If you scroll down here, you can see a large number of them clustered around a bird feeder, which will give you an idea of how pretty they looked as Christmas tree ornaments.
