I dropped by Tucson Botanical Gardens for lunch today and took a few pictures. Lots of flowers blooming. Tucson springtime (and pollen counts, sneeze) is here. I was intrigued by this flower in particular, very complex. Any of you plant people out there know what this is?
Update: After a little research tonight, this appears to be a Passiflora caerulea, also known as the blue passionflower.
