In my previous post I asked if you could identify what was in the Palo Verde Tree. There were actually two things. A growing Saguaro (on the left) and the spinney remains of a Saguaro (on the right). The Saguaro spines are very interesting and I never had a clue that was what made a Saguaro stand tall until I moved to Arizona. Here are the free standing remains. People turn them into walking sticks, fencing, and home decor.
If you notice the Saguaro's are fat and happy filled with water right now. (above) You can see this if you look closely and see how far apart the "V" indents are.
When there isn't enough water the "V" is closer together. (above)
