1: Add some rocks to the bottom of the vase. This will help with drainage when you water them. 2: Add soil. I filled mine to about an inch from the top, but it wasn't densely packed so there was still plenty of room for plants. 3: Plant a group of small plants in the soil. Be sure to space out any colorful cacti. 4: Cover the top of the soil with a thin layer of rocks. It's just for looks! So cute... done!

Someone else has commented that this is a Mexican Fence Post cactus. See the comments below.
