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 long been a staple in European gardens for decades.

There are many different kinds of penstemon. The leaves are lance-shaped 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.

Plant It With


Lady's mantle

Lady's mantle has foamy sprays of chartreuse flowers in late spring and is a fine companion for early penstemons in full sun.

Lamb's ears

A low carpet of fuzzy silvery lamb's ears at the feet of brightly colored penstemons presents an interesting combination. Good drainage and full sun will please both.

Catmint

Smaller catmints are fine in combination with penstemons. The gray foliage and loose spikes of lavender flowers complement each other.
