You have my curiosity and interest up on this on this subject, and knowing nothing about it gives me something new to learn. I'm sure this information would be helpful to someone else like me who knows little or nothing about it. I had previously cut out the spent flowers, but took some pictures of the leaves just below where the flowers used to be. These would be easier to illustrate something unusual like the one you have circled above. Here are three pictures where I used my macro setting.
Appreciate all your help- Thanks!
