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.
