Cactus at gardens

Busy busy day but lots of fun. Went to a couple of botanic gardens in Tucson. The plant life is all so intereting because it is so very diferent from where I live. It is also amazing to learn and see how plant life has adjusted to this harsh climate. Taken with iPhone and adjusted with photogenie app.
Uploading with my blip iPhone app, so I don't have computer with me. There are comments iwould like to respond to but it is somewhat difficult. Will wait till get home. Wanted to say I appreciate the comments.
