Long Term:

Penstemon species establish and spread slowly via seed distribution. They are not considered "weedy" or invasive species, but can spread into adjoining vegetative communities under ideal climatic and environmental conditions.

Winter:

Leave some stems for frost protection and mulch with straw in winter, if necessary.

Spring:

Blooms heavily in late spring, reblooming in late summer if lightly trimmed after the first flush.

Summer:

Remove spent flowering racemes to prolong bloom. Plants may be cut back to basal foliage after flowering to improve appearance of the planting.

Fall:
