Marcia Donahue is a self-described sculptor and devotee of the Roman goddess Flora. Her iconic garden is a riotous celebration of color and form. The gurgle of the monumental water feature draws you down narrow paths. Chickens run about in this jungle of lush aromatic plantings. Ceramic surprises -- oversize, overhead, everywhere -- demand attention and contemplation. A collection of bowling balls. A big pot filled with spoons, all turned inward like the petals of a silvery succulent. I could have drawn here all day.
