Is this a flower competition?

All of the following pictures were taken on the esplanade in Yokohama harbor.  As you can see the plots all have descriptive titles, plus perhaps information on the person or firm that created each plot.  In addition, there was a tent set up selling plants, which I did not photograph.  There really isn't anything to say, so I will only provide the captions.
