We spent some time in March hiking in the Tucson area.     There were wildflowers on the trails, but we also visited a number of gardens.    The first was the Arizona-Sonora Desert Museum.    The 98 acre facility had a zoo, an aquarium, a natural history museum, an art gallery, and a desert botanical garden.    We had hiked in Saguaro National Park in the morning, then enjoyed the Desert Museum in the afternoon.      Most of the plants in the gardens were cacti or succulents and related desert plants, but a few were also desert perennials and annuals in flower.    A sampling is provided here in a gallery.    Click a image for a lightbox view and a caption/ID:
