Yesterday, I was at Sutro Baths in San Francisco. I checked out the Land’s End Visitors Center, a treasure trove of temptation, especially books.

From How To Read Nature by Tristan Gooley:

Plants react to colors. For example, if we are dressed in blue we can change the way a plant grows, while if we wear red we will influence its timekeeping. The process by which plants grow toward light is called phototropism and is only influenced by blue light. Red light, on the other hand, influences photoperiodism, which governs the plant’s sensitivity to the time of year. The changes in a plant that result from our choice of clothing color may be imperceptible to us, but the knowledge that they are reacting can change the way we think about them.
