On the hills north of Tunis I found these tall thin plants. They look identical to ones we used to see in the Chihuahua Desert of southwest Texas. I don't think this photo will show it, but during wet seasons, the stalks are covered with yellow buds that turn white at the top.
The best part of doing this painting was having my son working beside me on a painting of his own. I cleared a space for him in my studio, prepared a piece of paper for him and let him pick a photograph he wanted to work from. Then we just worked side by side, painting and talking about things. I don't know if he'll remember it tomorrow, but I will treasure it for the rest of my life.
