Last week, I noticed several of these plants growing along a creek that I often walk by. I believe that this is called a Canada thistle. I'm told that it is considered to be a noxious, invasive species in 43 states. Basically, it's a weed!
In any event, I found the subject to be interesting. So, I removed this one small section of the plant and brought it home with me to photograph it.
I quickly set up a miniature "studio" on my kitchen table. The studio included a small piece of white foam board as my background. I lit the background with a tiny flash (the Nikon SB R-200):
I then lit the plant with a somewhat larger flash (the Nikon SB-900). I handheld the SB-900 and aimed it through a diffuser. Both flashes were triggered remotely by the Nikon SU-800. The light output of each flash can be set directly through the SU-800--which is positioned on the hotshoe of the camera (Nikon D850). The lens was the Nikon 200mm f/4 Micro.
Here is the final result:
