Penstemon

Penstemon

This North American native plant has a home in nearly every garden with flowers that hummingbirds love. Long blooming with brilliantly colored, tubular flowers, penstemons -- ironically -- have been a staple in European gardens for decades.

There are many different penstemon types. The leaves are lance-shape or oval, sometimes purple-red as in 'Husker Red'. Some Western species need outstanding drainage to dry conditions and won't thrive during wet weather. However, many, such as 'Husker Red', thrive in a wide variety of conditions. Just be sure to provide excellent drainage. Mulch in areas where a type is marginally hardy.
