The Christmas tree has snow, now to dress up the palm tree. A few ornaments should brighten it up.
The nice thing about the ornaments for the palm tree is that because I just wanted the the round ball type ornaments, they were fairly easy to model. I chose to go with a basic approach in the shape since it fits better with the look of the rest of the scene. First I created a sphere to a relative size. Then I created a cylinder to act as the little metal bit that goes over the top where the hook is attached. I then chose to extrude the top interior ring of polygon faces up to make that bit of the ornament that goes in the metal bit. With that created, I scaled the cylinder to fit just over the extrusion and just around it. I had to do some scaling of the cylinder to get it just right. I applied the turbosmooth modifier to the sphere shape first and found that the definition between the extruded portion and the rest of the sphere was too soft and so I add a couple of edge loops to create a more defined corner. I applied the turbosmooth modifier to the cylinder as well and had to add a
few edge loop so that the top corner/edge was sharper as well as the bottom part.
With the ball and the topper part being two different objects it was fairly easy to apply materials to them. The trick was finding the right thing. I finally settled on a gold foil material. It was very shiny and a little washed out. But looks good so I kept it. For the 
topper I went with a basic titanium. I didn’t what it as shiny as the gold foil look and the titanium worked out nicely.
I also created a hook to hang the ornaments by. This helped immensely with making sure I got the placement right.
I created the hook from a cylinder with many more sections so I would have enough edges to properly curve the end.
Then I selected the very end and using the soft selection tool I rotated and moved the end to get the basic shape. I added another set or two of edge loops and selected the edge loops and adjusted those individually to get the shape I wanted. I put a zinc material on the hook so that it wasn’t shiny and was even a bit more dull and matte looking that the other two components. This got the first ornament created. To make the copy process easier I grouped all three items. That allowed me to select the group and move it or rotate it or whatever else I might need to do.
I copied the ornament group and then opened it so I could change the color of the material on the ball part. In setting up the material, I could see where I could change the color, so first I did that and chose a lovely red. It looked great in the preview and not quite so awesome on the actual object, it was a bit faded or washed out. I found a setting in the material that let me adjust the color saturation versus the texture so I was able to get a 
deeper red on the ball. It didn’t look quite right where I put it so I moved the red ball up higher in the leaves where it supplied some contrast to all the green.
One more ornament to add and make it green. And this should do. However, it was pointed out to me that where I had the green ornament, it got lost in all the green of the palm leaves and the cactus.
So I swapped the green and gold ornaments around to make it easier to see each of them.
That gets the palm tree decorated.
