I'm sure that my combination of flowers on this grow pole is probably wrong but I get a kick out of mixing different flowers in the stacked containers each year. This stack of four containers has 16 grow sites and I mixed petunia, dusty miller and and alyssum. An experienced florist could have a ball with these and some mix of thrillers, fillers, and spillers. :-) Ive got some more grow poles to plant. You can see how the plant sites arranged, 4 per pot, 16 per pole. I need ideas of what quick growing annuals I could pick up at the nursery that would look good on a pole.
