Lungwort (Pulmonaria) is a pretty flower shaped like a trumpet that comes in an array of colors like red, blue, white or violet. When the plant's stems are only 1 inch out of the ground the plant will begin blooming. Lungwort grows about one-foot tall and can spread to 20 inches. These plants have distinctive speckled leaves, and prefer moist soils.
Columbine is a perennial that does very well in the Arizona shade--especially the yellow ones. During winter, the plant will go semi-dormant.

The leaves have a scalloped-shaped appearance and are blue-green in color. The flowers are shaped like spurs. Columbine is a perennial plant that will reseed.
Wax Leaf Begonia
The wax leaf begonia is an almost constant bloomer. Wax begonia received its name because the leaves have a waxy appearance. Depending on the variety, Begonias range in growth between 6 and 18 inches tall and spread between 6 and 12 inches wide. The leaves come in red, bronze, green or even variegated. The flowers, which bloom as either single or double flowers, vary in shades of pink, white or red.
Impatiens are tender perennials, but most of the time they are considered an annual. They range in color from white, pink, red, salmon or orange. They prefer a moist soil with mulch around them.
