How to keep Pentstemon X Hybridus.
Water
Beardtongue flowers are relatively hardy and tolerate drought well. During the summer, it is best to provide them with about an inch of water every week for vigorous growth and profuse blooming.
Temperature
These flowers are best grown in USDA hardiness zones 3 through 9, although some varieties are only hardy in zones 4 or 5. They adapt well in a wide range of conditions in these zones and thrive in various humidity levels.
Pruning
These plants rarely need pruning. However, your beardtongue plant may benefit from deadheading faded blooms until the stem to stimulate blooming.
