Sorry, but the picture didn't show up for me, Melinda.

I've only had Midnight Blue for one year now, and the first time it bloomed I, too, was disappointed. The next batches of blooms (the first had only one bloom) were much more purple and I was quite happy with the result. I had a mild summer last year, so I don't know how different the blooms look in different tempuratures. Either way, it's healthy and vigorous for me with lots of lovely blooms!
I hope yours will make you as happy as mine has made me.

There is no such thing as a blue rose. Not even the transgenic roses with delphinidin are blue because the cellular pH of the rose genus isn't acidic enough to express blue. As for purple roses most start out a deep saturated crimson red that progressively "blues" until shades of purple and violet are achieved. The color is extremely unstable and rarely lasts more than a day or two as the bloom fades out to grayish mauve.
