I saw a planter like this once when I was on a trip inVancouver WA. They were stunning and their pots of flowers everywhere were mind blowing. So this planted the seed to make one of my own. I looked on the internet and they do sell containers that you can mount on a steel pole for about 75 bucks. I was determined to figure it out by myself and make one cheaper.
I am thrilled with the result and my cost was well under 35 dollars. Of course that doesn't include the flowers!
