The idea is that the milk can has tipped over and spilled out the “milk”; in this case, plants. In keeping with the theme, I also have my “Ice Cream Sundae” totem in front of the Planter Bench made from an old metal bed frame.
For the milk, I planted some Nettle, which is a perennial, but because they won’t fill in for a couple of years, so I filled in with Dusty Miller, which is an annual in my area. The Dusty Miller is much whiter than the Nettle.
I had a milk can that I was no longer using as a plant holder, so it came to this garden bed. In the inspiration photo, they used a much smaller can, so I can see where they could get away with less cost on the flowers. I left the can as well as the bench rusty and peeling paint.
