Penstemon whippleanus, also called Whipple's Penstemon, is a beautiful flowering plant native to the western United States. While Penstemon whippleanus may be its scientific name, there are other colloquial terms that represent this plant's beauty and characteristics. Several common synonyms include Whipple's beardtongue, Whipple's penstemon, and blue penstemon. These terms reference the plant's signature blue or purple flowers, which bloom in various shapes and sizes across the plant's tall, upright stems. Additionally, Penstemon whippleanus is a drought-tolerant species, meaning it can thrive in arid conditions with little water. As such, another fitting term for this plant could be the drought-resistant penstemon.
