Flowering spikes with trumpets of vivid blue. Carefree and drought resistant, this Penstemon sports an interesting purple blush at the stems. Glossy green foliage is a nice complement. Flowers first year.
Penstemon are an American native with colorful tubular bell-shaped flowers. Does well in a drier climate and is drought resistant once established. Avoid too moist (wet feet).
Best in loose, gravelly soil with good drainage. Pinching back taller varieties when about 12" tall will produce more compact plants. Can be divided every 3 -4 years in spring by digging mature rhizomes and replanting. Will self sow. Foliage can be trimmed after blooming to freshen. Clean up in fall or spring. May benefit from loose winter mulch in colder zones.
