flower garden ideas

While I was at the botanical gardens They had a cute idea that might be great for someones garden
They took very large planters and in each one planted a different color. They took a rebarb pole ( you can get them at any hardware store) they are used for cement and building things. Took 3 paint cans and dripped whatever color the flowers are over the edge of the paint cans like the paint was dripping into the flower bed. Drill holes in different directions coming up threw the paint cans. It was a cute idea.
