Below is a weeping Colorado Blue Spruce which, unless staked, will want to grow downwards. There are two horizontal stakes forcing the branches to grow horizontally. The upper most stake is holding the former central leader which is the habit of most pines causing the typical pyramidal form of the plant.

This plant is 10 years old or so and 5’ tall:
