Our work in the Panhandle yesterday centered on a thicket of trees, and with the help of McClintock's book, I identify them as pittosporum, a.k.a. cheesewoods. These trees aren't instantly all that impressive, but on closer inspection, their flowers are unique and beautiful. And they are one of the more common trees in the Panhandle - I spotted them all over today once I knew what to look for.
Different species of cheesewood produce different color flowers. Here are two of the different flowers in bloom today. Watch for thicker blooms on the cheesewoods in the Panhandle this spring and summer. And search Flickr for Cheesewood or Pittosporum for better pictures, including shots of the gooey seeds that erupt from pittosporum fruits in the summer.
