Here's a fun photo. I thought I was seeing things when I noticed these colored needles on some of the saguaro at Tohono Chul Park in Tucson. No! Each year, they've marked the growth as part of a botanical experiment. (The docents couldn't give me any more detail than that.) One of the interesting things I noticed is the growth on each saguaro seemed to be different, leaving you to wonder if the saguaros all grow at their own pace.
