Penstemon eatonii (Firecracker Beardtongue) - An evergreen perennial/ subshrub to 2 feet tall by about the same width when in flower with large paired lanceolate leathery leaves and vivid scarlet-red tubular flowers that rise above the foliage in late winter through spring. Plant in full sun in a very well-drained soil or raised mound and avoid summer irrigation. A very hardy plant tolerates temperatures well below 0 F and is useful in USDA zones 4 and above. This is a nice plant for naturalizing in a unirrigated hot area where its bight flowers can be enjoyed and attract hummingbirds yet it is not browsed by deer or rabbit. To tidy up the plant removed spent flower spike but be sure to leave some seed capsules to allow this plant to reseed. Penstemon eatonii is a widespread species native to the western U.S. from eastern Southern California to the Rocky Mountains where it can be found growing in desert mountains in the Pinyon-Juniper Woodland and Creosote Bush Scrub plant communities. The entomology for the genus name is a reference to the stamens of the flower but the precise meaning has been in debate. It is often written that it come from the Greek words 'penta' meaing "five" and 'stemon' meaning "thread" or "stamen" in reference to it having five stamens when the one staminode is included, but others offer another meaning since it was Linnaeus who first spelled the name for the genus incorrectly as Pentstemon, which would have corresponded with the root word 'penta'. When John Mitchell originally published the name for the genus in 1748 he spelled it in the manner we currently do, as Penstemon. This leads to the idea that the "pen" in Penstemon is not a reference to "five" but to the unusual combination of Latin and Greek words with the Latin word 'paene', meaning "nearly" or "almost" and the Greek word 'stemon' meaning "thread" or stamen in reference to the staminode, which is almost a functional stamen. The specific epithet honor American botanist Daniel Cady Eaton (1834-1895) who studied under Asa Gray and became one of America's first professors of botany and Curator of the Yale Herbarium. Another common name for this plant is Eaton's Penstemon.
