Stanford Cactus Garden and Eucalyptus Tree

Somehow I managed to live near Stanford University for many years now, but never got to visit the Cactus Garden there. It is also called an Arizona Garden and is quite old. There were many things to draw, but the time was limited, so I think I would call this a reconnaissance sketching - I will be back to draw an old Joshua Tree and all the textures of many interesting succulents! I quickly put this sketch together from a shade of a tree where I could observe a plant being simultaneously eaten by a hummingbird and a squirrel.  

And of course, an eucalyptus tree is always a reason to stop by and sketch!
