Apple Blossom penstemon has soft to bright pink tubular flowers with white throats. Flowers form along tall spike early summer until frost. It is drought tolerant. Attracts hummingbirds and butterflies; is deer and rabbit resistant. The penstemon hybrids are generally not as cold hardy as other penstemons, (listed as Zone 7, though some sources list it as 5) but they make fine annuals for filling in a perennial border or for containers. Grows 2 to 3 feet tall and about 12 to 15 inches wide.
Hybrid penstemon can be less cold-hardy than other penstemons. They make great annuals for containers and filler in perennial borders as they have a long bloom season. Grow in full sun and well-drained soil. Like other penstemon, they prefer a gravel mulch, but if you use bark, pull it back from the crown of the plant so as to not cause crown rot.
