Zinnia are enviable. They seem to perform exemplarily for everyone else and everywhere else. They have never done well for me though. I can not explain why. I stopped trying to grow them many years ago, but I encounter them at work, where the other horticulturist grows some as warm season annuals. This year here, some performed reasonably well as bedding plants, and a few more bloomed impressively within a pair of half wine barrels. They are done now that the weather is cool, but I got a few pictures of them as they were removed and replaced with pansies for winter.
1. Yellow is a primary color, but the scarcest among the few prolific zinnia that grew in a pair of half wine barrels through summer. Only one of the ten zinnia here bloom yellow.

2. Orange is a secondary color between yellow and red, but is a bit more abundant in our barrels than either yellow or red. Maybe three or so of the ten zinnia here bloom orange.

3. Red is another primary color, which is beyond orange from yellow. Perhaps two or so zinnia bloom red, but they are less profuse than those that bloom pink, orange or white.

4. Pink is not really a color, but is merely a tint of red, or red mixed with white. Only two of the ten zinnia here bloom pink, but they are bigger and more profuse than the others.

5. White should be my favorite, but to me, seems to be mundane relative to other colors. Two of the ten zinnia bloom white, but they are neither prominent nor prolific in bloom.

6. Rhody is as unimpressed with our unusually florific zinnia as he is uncooperative with my attempts for a good picture of him. Fortunately, even a bad picture of Rhody is good.
