People often ask for plants that attract hummingbirds. Because of their tubular flowers, Penstemons are a great choice. I’ve been watching hummers return to this planting of Rocky Mountain Penstemons in my backyard every morning and evening for a couple weeks now. Before that, the birds were busy visiting my nearby Snowberries. Red flowers are especially good at attracting hummingbirds, but Penstemons of any color work! They are also an excellent food source for different types of bees and an occasional butterfly.
