Just when we think we understand how things work, Nature scrambles our expectations!
Chlorophyll has Colleagues! – IV
Although chlorophyll is widely known as a plant pigment, it is not alone in giving us colorful trees.

HOW it all began
I wasn’t always an avid reader. I remember being in first grade and being taught from the Dick and Jane series how to read. For the life of me, even at six years old, I could not fathom how anyone could rouse any interest in “Watch Dick run” or “Look at Spot.” Apparently I did grasp the process because I never need any further help with the subject but reading was definitely not a priority.
Writing is work!
Reading eventually became a source of great pleasure for me. Writing, however, was an altogether different matter. Elementary school was full of compositions and book reports. In high school and beyond, no semester was complete without at least one research paper. And I cannot say that I ever enjoyed it!
New Post: what is that tree!!!
We moved into our present home almost forty years ago. While the property had lawns front and back, there was little evidence that the previous owners were interested in gardening or landscaping. There were, however, lovely trees, some of which were quite large. In the front, close to the public walkway, there was a spindly tree with very large leaves which I could not identify.
