365Caws is now in its 16th year of publication. If I am unable to post daily, I hope readers who love the natural world and fiberarts will seize those days to read the older material. Remember that this has been my journey as well, so you may find errors in my identifications of plants. I have tried to correct them as I discover them. Likewise, I have refined fiberarts techniques and have adjusted recipes, so search by tags to find the most current information. And thank you for following me!

Xanthous
Day 2: Hmmm...I might have been lost down the rabbit hole forever, but for a detour it took into certain controlled substances. I was reading up on xanthophyll, the pigment which provides the beautiful yellows revealed in autumn when it is no longer masked by chlorophyll ("xanthous" means "yellow"). I was intrigued to learn that some herbicides target xanthophyll because it protects plants against light toxicity. By destroying the pigment, these herbicides open the plant to light-burning. As I read on, I found myself pondering the significance of xanthophyll and the seasonal reduction of chlorophyll when natural light levels diminish, and the next thing I knew, I struck a whole Google page devoted to suggested reading for commercial growers of a product I'd prefer to see made illegal. You know what they say about not being able to "unsee" something. I may never be able to look at my vining hydrangea in quite the same way again.
