The Tower is mostly a Mary Jane Stacking unit I've had for many years. Don't think they sell this large of one anymore. Since it's in the driveway, I used a big black pot as the base instead of the one that came with it. That way I could fill it 1/2 way full of gravel and then ran a piece of rebar down the center of the whole thing so it won't get blown over by the wind. It has no water source. Water that goes in the top drips down through the system, but I usually also water each hole separately to be sure all get really wet. Interested I the one Dave is testing but this seems to work fine for me.
The zinnias are growing in Earthboxes. The cannas too. I didn't have much luck with vegetables in them. Growing some Black Eyed Susan vines in a couple other ones and chocolate mint in one too. Expensive pots for annuals, but I've given up on vegetables.
Julia that coleus is Ruby Dreams. Really nice. I used to have Golden Dreams too but the cuttings didn't make it through the winter.
