Set amid residential neighborhoods in midtown Tucson, these gardens are an oasis of greenery and, though small, are well worth a visit if you're interested in desert plant life, landscaping, or gardening. On the 5 1/2-acre grounds, there are a dozen different gardens that not only have visual appeal, but also are educational. You can learn about creating a garden for birds or for butterflies, and then see what sort of crops the Native Americans of this region have traditionally grown. A sensory garden stimulates all five senses. A toy train layout and a tropical butterfly house (open fall through spring) make this a surprisingly good place to bring the kids.
