Attracting hummingbirds is a top priority for many Tucson and Green Valley area residents, and nothing brings those tiny birds to your desert landscaping like the penstemon.
There are so many penstemons to choose from, with flowers colors ranging from red and orange to delicate pink. Many of the penstemon species are native to Arizona, but only a few to the lower elevations. But that is not a problem as long as you plant the species particular to higher elevations in either filtered shade, such as under a mesquite tree, or at minimum with afternoon shade. Only the natives to lower elevations can take all day sun.
All penstemons need good drainage or they will rot out. They also do not care about soil amendments, so stick with native soil.
These are low maintenance perennials, requiring only the removal of spent flowers. Sprinkling the seeds around your yard before the birds get them all is a great way to bring in more plants and more hummingbirds. Try the Pineleaf Penstemon, with its bright orangey-red flowers.
